The article is devoted to the actual problem of surface water monitoring in the zone of influence of oil and gas producing enterprises. Aims and Objectives – comprehensive pollution assessment of natural water bodies located in the zone of influence of wastewater injection landfills of the integrated gas treatment plants IGTP-1 and IGTP-2 of the Yamburg Oil and Gas Condensate Field using the water pollution index. The pollution assessment of natural waters was carried out in accordance with State Standard 17.1.3.07-82 «Nature protection. Hydrosphere. Procedures for quality control of water in reservoirs and stream flows». The average regional values of the controlled components correspond to the «Handbook on the use of average regional values of controlled Component content at monitoring Sites when assessing the state and level of environmental pollution in the Yamalo-Nenets Autonomous Okrug». It has been concluded that, on average, the water pollution index of the studied territory for the period since 2019 up to 2021 corresponds to the 2nd quality class («clean»), excluding from the calculation the concentration of iron – a typomorphic element of the natural waters of the North taiga zone.

Within well life, well treatments are carried out to increase productivity by stimulating initially unproductive zones. These measures include hydraulic fracturing, multi-stage hydraulic fracturing, matrix acid treatment, acid fracturing, etc. These processing methods allow existing wells to support hydrocarbon production without drilling new wells. During these treatments, certain specialized particles or technical devices are used for isolating an already existing perforation or for liquid flow diverting. These particles or devices are usually called flow diverters, which can prevent the use of a drilling rig to create temporary physical barriers, reducing the overhaul cost. Recent improvements in flow deflection technology allow the use of various decomposable particles that act as a temporary bridge either at the perforation entrance or inside an existing crack. The basic principles of the injected compounds flow deflection are to create filtration resistance to the advance of the acid composition in the highly permeable part of the collector and the coating of untreated cracks. This article discusses rejecting agents, their origin, types, applications, and some case studies in which the use of rejecting agents has proven to be the most effective.

In recent years, there has been a steady development of systems for the production of small-scale liquefied natural gas for gas supply to remote consumers in cases where the possibilities of pipeline construction are limited. In addition, there is a tendency to use liquefied gas to replace liquid hydrocarbon fuels (gasoline, kerosene, gasoil, fuel oil). Due to the growth and emergence of new industries for liquefied natural gas consumption, the infrastructure necessary for its production, transportation and storage is being developed. The article presents an analysis of the use of the most common polymers for the pipeline construction in the oil and gas industry. The possibility of using ultra-high molecular weight polyethylene for the construction of process lines for pumping cryogenic liquids was considered. The results of experimental studies on tensile strength test and Charpy impact strength test after exposure to liquid nitrogen are presented. As a result of tensile strength tests, an increase in the strength properties of the material was observed while maintaining its plasticity. The breaking stress was 37.7 MPa, the yield strength was 27.1 MPa at liquid nitrogen temperature, while at ambient temperature, the specimen failed at 26.9 MPa, the yield strength was 20.2 MPa. The specimens, tested for impact strength by the Charpy method, after exposure for 2 h in liquid nitrogen, a certain margin of plastic properties was also showed. The stress-strain state of a liquefied natural gas pipeline made of ultra-high molecular weight polyethylene in an insulating coating was simulated using the ANSYS Mechanical software package, taking into account its thermal interaction with the soil. The maximum equivalent stress in the model was 14.4 MPa, with calculated value of 12.7 MPa, which does not exceed the yield point of the material. Thus, ultra-high molecular weight polyethylene can be considered as a promising material for use at cryogenic temperatures.

The trunk oil and gas pipelines are under operational loads affecting the strength and reliability of the structure. The most significant effect of loads is manifested at pipeline crossings across rivers. The stability of underwater pipeline design position and thus its reliability is achieved by ballasting with the required intensity. The current regulatory document SP 36.13330.2012 provides for the required intensity determination, taking into account the water buoyancy force and pipeline crossing along the longitudinal profile of the transition. At the same time, it should be noted that ensuring pipeline bending along the longitudinal profile of the crossing with the use of ballasting of the required intensity also depends on the internal forces acting in the pipeline wall during operation. However, this document does not take into account operational loads when determining the required ballasting intensity. In addition, ballasting with the ensuring pipeline bending along the longitudinal profile of the crossing leads to the occurrence of bending stresses, in some cases quite high, which affect the level of total stresses, strength and reliability of the structure. In many cases, water occupies only part of the concave section of the pipeline at crossings. Taking into account the above conditions and features, studies of the ballasting of underwater crossings of trunk oil and gas pipelines were carried out. The aim of the work is to obtain analytical dependences of the ballasting intensity and bending stress in an underwater pipeline at different altitude water levels at the transition from operational loads and geometric characteristics of the crossing. The research method is a theoretical study of the stress-strain state of an underwater pipeline under the action of operational loads and weights. The dependences of ballasting intensity with weights of the underwater pipeline on the operational loads and the geometric characteristics of the transition at different elevations of the water level at the transition are obtained, and the highest bending stresses in the pipeline wall at the underwater crossing are determined. Recommendations to reduce the total longitudinal stress level in an underwater pipeline are given.

The article deals with the issues of environment purification from oil and oil products. In particular, data on the technology of re-cultivation of soils contaminated with heavy fractions of oil by reagent encapsulation method are given. The main aim of the work was to search for effective polymers in the composition of the encapsulated material based on quicklime and industrial fat, which provides a high degree of carbonization of contaminated soils. M-100 grade fuel oil was chosen as the heavy fraction. The polymers: carboxymethylcellulose, sodium alginate, xanthan gum, and polyphepan – were investigated. In the course of the studies, it was found that the most durable granules with increased water resistance and low toxicity are formed when using carboxymethylcellulose.

The problem of treatment of drilling wastewater from mechanical impurities and its reuse for technological process is unresolved. The study summarizes results of researches in drilling wastewater treatment methods. It is relevant for areas of extraction of hydrocarbon raw materials. The authors suggest applying a scheme of treating drilling wastewater from mechanical impurities consisting of two stages of purification – sedimentation and filtration through various materials for loading filters: sawdust, peat, soil (medium loam), ash, starch, household dust (a mixture microorganisms), charcoal, gauze, polyester wadding (lighat, voluminous, elastic nonwoven fabric), foam rubber (soft cellular synthetic foam with high elasticity and breathability). Soil, ash, starch, peat and coal were cleaned from impurities and ground to a fine state. Eleven individual materials and their various combinations were studied as filter loads. The tests were replicated three times. Untreated drilling wastewater served as a control background sample for calculating efficiency. The possibility of wastewater treatment by sedimentation and subsequent filtration using industrial waste as a loading material for filter was researched. It was found out that treatment efficiency increases when wastes used in filters are grinded to microparticles.

In the oil and gas industry, one of the key tasks is to assess the current state of pipelines and equipment. Most of the existing methods used to assess depreciation are narrowly focused and expensive, for example, flaw detection of downhole equipment, tubing, rod and pumping equipment, which can eventually reach the cost of the equipment itself. To date, one of the main methods for assessing the equipment state is the analysis of its operation time, which directly depends on the identification accuracy. Various technological solutions are used as an identifier, for example, barcodes, seals with technical information, however, such controls are unreliable, wear out quickly, and, as a result, it becomes difficult to correctly identify them. The paper considers the technology of radio frequency identification (RFID) – «RFID-tags», describes the operation principle and its features. The basic scheme of the tags, conditions and purposes of application in the oil and gas field industry and, in particular, in the pipeline transport. The cases of technology implementation by different foreign and domestic companies are described, and some ways of their potential development are indicated. The analysis of technical solutions is given, the advantages achieved in the implementation of RFID systems are compiled. The key and promising factors for the use of this technology in pipeline transport are the possibility of minimizing risks in case of accidents and oil spills, minimizing environmental disasters for both organizations and the environment, since the cost of equipping RFID tags and RFID reading equipment can be insignificant in comparison equivalent.

Основным видом щелевых уплотнений роторов магистральных насосов для перекачки нефти и нефтепродуктов являются плоские щелевые уплотнения. Их применение позволяет обеспечить сокращение объемных потерь перекачиваемой среды из напорной области во всасывающую через зазор между ротором и статором – перетечек, которые являются одним из факторов снижения объемного КПД насоса при эксплуатации. В качестве щелевых уплотнений для магистральных насосов типа НМ наиболее распространены плоскощелевые и плоскощелевые ступенчатые уплотнения. Однако при их использовании величина объемных потерь остается ощутимой (для насосов большой мощности – до 1 % в полном КПД насоса), что требует соответствующих технических решений. Целью настоящей работы является совершенствование узла щелевого уплотнения для сокращения перетечек и, соответственно, повышения энергоэффективности магистрального насоса. Авторами проведено исследование с оценкой технической целесообразности применения сотовых уплотнений в узлах щелевых уплотнений роторов магистральных насосов. По результатам компьютерного моделирования течения в проточных частях зазоров установлено, что сотовые уплотнения обеспечивают снижение объемных потерь расхода в проточной части магистрального насоса и превышают характеристики применяемых в настоящее время плоских щелевых уплотнений. Разработаны требования к сотовым уплотнениям рабочих колес с учетом параметров эксплуатации магистральных насосов НМ. The main type of groove rotor seals for mainline pumps for oil and oil products are flat groove seals. Their use allows for the reduction of volumetric losses of the pumped medium from the discharge area to the suction area via the clearance between the rotor and stator - overflows, which are one of the factors reducing the volumetric efficiency of the pump during operation. The most commonly used groove seals for NM mainline pumps are the flat-groove and flat-groove stepped seals. However, when they are used, the value of volumetric losses remains tangible (for high-capacity pumps – up to 1 % of overall pump efficiency), which requires appropriate technical solutions. The purpose of this work is to improve the groove seal assembly in order to reduce overflows and, as a result, improve the energy efficiency of the mainline pump. The authors conducted a study to assess the technical feasibility of using honeycomb seals in groove seal assemblies of mainline pump rotors. According to the results of computer simulation of the flow in the flow paths of clearance, honeycomb seals reduce volumetric flow losses in the flow path of the mainline pump and outperform the characteristics of the currently used flat groove seals. We have developed requirements for honeycomb seals of impellers, taking into account the operating parameters of NM mainline pumps.

However, when they are used, the value of volumetric losses remains tangible (for high-capacity pumps – up to 1 % of overall pump efficiency), which requires appropriate technical solutions. The purpose of this work is to improve the groove seal assembly in order to reduce overflows and, as a result, improve the energy efficiency of the mainline pump. The authors conducted a study to assess the technical feasibility of using honeycomb seals in groove seal assemblies of mainline pump rotors. According to the results of computer simulation of the flow in the flow paths of clearance, honeycomb seals reduce volumetric flow losses in the flow path of the mainline pump and outperform the characteristics of the currently used flat groove seals. We have developed requirements for honeycomb seals of impellers, taking into account the operating parameters of NM mainline pumps.","PeriodicalId":42555,"journal":{"name":"Nauka i Tehnologii Truboprovodnogo Transporta Nefti i Nefteproduktov-Science & Technologies-Oil and Oil Products Pipeline Transportation","volume":"292 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79398524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Рассматриваются вопросы выборочного ремонта и усиления участков трубопроводов с патрубками, вантузами, несанкционированными врезками, заплатами и другими конструкциями, ремонт которых не предусмотрен действующей нормативной документацией. Для ремонта таких участков предлагается использовать разрезные тройники, которые монтируются на трубопровод сварными угловыми швами без остановки перекачки продукта. Контролировать качество таких швов трудно, при этом в случае возникновения дефекта их ремонт сваркой нежелателен, так как повторное наложение термического цикла сварки вызовет в металле структурные изменения, рост сварочных напряжений и деформаций, что в совокупности приведет к снижению несущей способности стенки трубопровода. Проведен отбор разрезных тройников по критериям прочности, герметичности и объему сварочных работ при монтаже. Для снижения остаточных сварочных напряжений в корневой части монтажных швов предложено увеличить длину тройника по магистрали, что, по расчетам, позволяет уменьшить напряжения в сварных соединениях разрезного тройника и увеличить ресурс ремонтного узла при циклическом нагружении почти на 20 %. Предложена технология монтажной сварки при отрицательных температурах (от –2 до –10 °С) включительно, снижающая вероятность образования холодных трещин в сварном шве. Приведены результаты циклических испытаний трубных катушек разного диаметра с приваренными разрезными тройниками, имеющими увеличенную длину по магистрали. Показано, что в широком диапазоне циклических нагрузок разработанная технология ремонта дефектов на действующих трубопроводах разрезными тройниками обеспечивает высокую надежность отремонтированного узла как минимум на протяжении 30 лет эксплуатации трубопровода. The issues of selective repair and reinforcement of pipeline sections with nozzles, tapping valves, unauthorized tapping, patches and other structures, repair of which is not provided for in the current regulatory documentation are considered. To repair such sections, it is proposed to use split tees, which are mounted on the pipeline with welded corner joints without stopping the pumping of the product. It is difficult to control the quality of such welds, and in the event of a defect, their repair by welding is undesirable, because reapplying the welding thermal cycle causes structural changes in the metal, as well as the growth of welding stresses and strains, all of which contribute to a decrease in the bearing capacity of the pipeline wall. The split tees were selected based on their strength, tightness, and the amount of welding work required during installation. It is proposed to increase the length of a split tee along the mainline to reduce residual welding stresses in the root part of the mounting seams, which, according to calculations, allows to reduce stresses in the welded joints of the split tee and increase the resource of the repair assembly by almost 20 % under cyclic loading.

正在审议有抽样修复和加强管道区域的问题，其中包括巡逻、活塞、未经授权的冲刺、补丁和其他未得到现行法规规定的建筑。为了修复这些区域，建议使用切割三叉戟，这些三叉戟被焊接在管道上，不受产品泵流的影响。这种缝合线的质量很难控制，但如果有缺陷，就不需要焊接，因为重新接合焊接周期会导致金属结构变化、焊接应力增加和变形，从而导致管道壁承载能力下降。在安装过程中，根据强度、密封性和焊接工作的数量，对三叉戟进行了筛选。为了减少接缝根部的焊接电压，建议增加三通管的长度，从而减少切割三通管的焊接电压，增加循环负荷的维修资源近20%。提供技术装配焊接温度负(包括- 2至- 10°c),降低了教育在焊接冷裂纹裁缝的可能性。这是对不同直径的管线圈的循环试验的结果，有固定的三叉戟，在高速公路上的长度增加了。显示，在广泛的循环负荷范围内，现有管道上的缺陷修复技术由切割的三重管提供了高可靠性，至少30年的管道维护。《选择与诺兹》、《惊喜》、《未知山谷》、《未知山谷》、《patches》和《另一段历史》、《神秘传说》都没有受到保护。这是一段很好的时光，这是一段很好的时光，这是一段很好的时光。It is difficult to control the quality of的welds and in the event of a defect, their repair by welding is undesirable because the welding热reapplying cycle的结构性changes in the metal as well as the《of welding stresses and strains all of主演contribute to a decrease in the bearing of the管道最终wall。这首歌的歌词是一首非常棒的歌曲，是一首非常棒的歌曲，是一首非常棒的歌曲。It is proposed to increase the header length of a split tee along the mainline to reduce residual welding stresses in the root part of the seams fdmi,主演,according to calculations allows to reduce stresses in the welded joints of the split tee and increase the资源of the repair assembly by almost 20% under cyclic地震。Assembly welding at阴性temperatures (from 2 to - 10°C包容性)to reduce the概率of cold cracks in the weld has been proposed。= =历史= =在威尔德·斯派特的挑战测试中，有一种令人难以置信的联想。这是一项公开的技术，用于在30年的赛区范围内进行回放。

Представлен исторический обзор становления технологии последовательной перекачки различающихся по качеству нефтепродуктов. Приведены предпосылки появления технологии, описаны первые экспериментальные исследования в этой области на трубопроводах в России и США. Показаны противоречивые результаты опытов по определению количества смеси, образующейся при последовательной перекачке разносортных нефтепродуктов методом прямого контактирования. Указано, что неоднозначные практические данные не позволяли достоверно оценивать и прогнозировать объем смеси и ее протяженность, для решения этих задач в сложившихся условиях необходимым являлось теоретическое обоснование процесса смесеобразования на границе контакта двух сред. Показано развитие теории последовательной перекачки: от упрощенной модели механического смешения жидкостей, предложенной в 1938 году В. С. Яблонским, до конвективно-диффузионной теории смешения, сформулированной в 1954 году Тейлором и ставшей основополагающей для дальнейших исследований. Отмечено, что активное внедрение последовательной перекачки в производство началось с конца 1940-х годов. В настоящее время это широко распространенная и используемая на крупнейших трубопроводах мира технология транспортирования, совершенствование которой в части теории и учета практических аспектов эксплуатации трубопроводов активно продолжается сегодня. A historical overview of the evolvement of the technology of different quality oil products batching is presented. The prerequisites for the emergence of this technology are given, and the first experimental studies in this area on operating pipelines in Russia and the USA are described. The contradictory results of the experiments on quantification of the mixture formed during the diverse oil products batching by direct contact are shown. It is indicated that the ambiguous practical data did not allow to reliably estimate and predict the batch volume and its extent. To solve these problems in the prevailing conditions, a theoretical justification of the mixture formation process at the two-medium contact boundary was necessary. The development of the theory of batching is shown: from the simplified model of mechanical mixing of liquids, proposed in 1938 by V. S. Yablonsky, to the fundamental diffusion theory of mixing, formulated in 1954 by Taylor, which became the basis for further research. It is noted that the active introduction of batching into production began in the late 1940s. It is now a widespread and widely used transportation technology used on the world’s largest pipelines, the improvement of which in terms of the theory and consideration of practical aspects of the pipeline operation is actively continuing today.
