In the structure of potential oil reserves in Western Siberia, the share of hard-to-recover reserves (HRR) is growing. At the same time, a significant share of these reserves is concentrated in low-permeability reservoirs. Horizontal wells using multi-stage hydraulic fracturing are the basis of technological solutions used for cost-effective development of low-permeability reservoirs by Russian oil and gas producers [1-4]. Due to the high efficiency of the subsea development systems with MSHF, oil production from such facilities exceeds oil production from traditional reservoirs and accounts for more than 60 % of the total oil production of the Company's fields [5]. The following characteristics are identified as the key parameters of the horizontal section, the number of hydraulic fractures, as well as the specific weight of the injected proppant at the frac stage. The decisions approved as part of the design documents for the development of facilities with TPP indicate a tendency to increase the length of the horizontal hole and the number of frac operations with a decrease in the specific mass of proppant on the port. The article examines the impact of these characteristics on the technological efficiency of wells. The purpose of the work is to assess the feasibility of increasing the technological complexity of HW with multi-stage hydraulic fracturing of the MSHF formation in the form of increasing the number of stages and length of the horizontal hole, as well as the specific mass of proppantane in the example of the AS10/1 Kondinskoye field development target. Within the framework of the study, three types of HW with MSHF were identified, the technological effectiveness of which was assessed in two ways. The first method consisted in comparing the magnitudes of the dimensionless productivity coefficient Jd (d. units) of three different types of wells with a horizontal end in relation to directional wells (FWS with frac) of the environment. Taking into account the similarity of the geological conditions of the neighboring wells, this method made it possible to assess how effectively the completion of the horizontal wells under study was completed. The multiplicity assessment methodology was developed by RN-BashNIPIneft LLC [6]. The second method was to compare the ratio of dimensionless productivity factor to the specific weight of proppant Jd/Mpr _ specific of the identified types of HW with multi-stage hydraulic fracturing (MSHR). This approach made it possible to take into account the effective thickness and permeability of the formation in the well drilling zone, as well as the weight distribution of the injected proppant. The results showed that if the length of the horizontal hole is constant, an increase in the number of frac stages while reducing the proppant weight on the port is impractical. Confirmation was also obtained based on statistical data that there is a relationship between the cumulative fluid withdrawal and the weight o
在西西伯利亚地区的潜在石油储量结构中，难采储量(HRR)所占的比重越来越大。与此同时，这些储量的很大一部分集中在低渗透油藏中。多级水力压裂水平井是俄罗斯油气生产商经济高效地开发低渗透油藏的技术解决方案的基础[1-4]。由于MSHF海底开发系统的高效率，该设施的产油量超过了传统油藏的产油量，占公司油田总产量的60%以上[5]。以下特征被确定为水平段的关键参数，水力裂缝的数量，以及压裂阶段注入支撑剂的比重。作为TPP设施开发设计文件的一部分，批准的决定表明，随着支撑剂在港口的比质量的减少，水平井的长度和压裂作业的数量有增加的趋势。本文探讨了这些特征对油井技术效率的影响。以AS10/1 Kondinskoye油田开发目标为例，该工作的目的是评估通过增加水平井段数量和长度，以及增加支撑烷的比质量，来提高MSHF地层多级水力压裂技术复杂性的可行性。在研究框架内，确定了三种具有MSHF的HW类型，并通过两种方式评估了其技术有效性。第一种方法是比较三种不同类型的水平端井的无因次产能系数Jd (d单位)的大小与环境的定向井(FWS与frac)的关系。考虑相邻井地质条件的相似性，该方法可以对所研究水平井的完井效果进行评估。多重性评估方法由RN-BashNIPIneft LLC开发[6]。第二种方法是比较所确定的多级水力压裂HW (MSHR)类型的无因次产能系数与支撑剂比重Jd/ mpr_的比值。这种方法可以考虑钻井区内地层的有效厚度和渗透率，以及注入支撑剂的重量分布。结果表明，在水平井段长度一定的情况下，增加压裂段数同时减少支撑剂在端部的重量是不现实的。根据统计数据也证实了累积出液量与注入支撑剂的重量之间存在关系。研究表明，对于最常见类型(1000 m, 10级)的MSHF地层，采用多级水力压裂的钻井HW并不是研究目标的最佳选择:对于1000 m的长度，最大级数应限制在每口井7-8个单元。建议对采用水平端接的生产井进行进一步的监测和分析，以收集更多的统计数据，并随着时间的推移进行比较。

Currently, when cementing casing strings, various formulations of buffer fluids are used, the choice of which is based on laboratory testing of its compatibility with specific drilling and grouting solutions. The development of market relations evolutionarily pushed manufacturers to obtain and use the most efficient, durable materials and technologies that meet the requirements of ISO 13500:2008 [11], ISO 10426-2:2003(R) [12].In foreign and Russian practice, leading oil and gas companies use integrated quality management systems. However, due to the influence of a number of socio-economic factors, there has been a sharp rise in the cost and reduction in the production of components, along with a continuous increase in the need for efficient materials in many industries. The use of components produced by domestic enterprises in industrial volumes makes them deficit-free, and in terms of price quite affordable and competitive raw materials [6].«RN-BashNIPIneft» LLC together with the «USPTU has developed a methodology to establish uniform requirements for the evaluation of buffer fluids for hydrocarbon-based drilling fluids when cementing casing strings. The methodological basis for achieving this goal is the concept of a systematic approach in the quality management of buffer fluids [8].

Technical diagnostics of in-service polyethylene-exhaust gas pipelines face a number of difficulties, since the existing methods of destructive control are not applicable for determining the mechanical and physical characteristics-stick of polyethylene pipes. The search for effective control methods that can most fully characterize the quality of pipe material and the interpretation of the results obtained are of scientific and practical interest. The article on the example of technical diagnostics of the polyethylene gas pipeline built in 1985 considers possible criteria for assessing the condition of pipes and their ranking by significance. It was found that polyethylene pipes produced during the development of their production did not always meet mandatory quality requirements and could have hidden defects in the form of inhomogeneities, cavities and cracks throughout the volume of pipe material. Based on the experimental studies carried out, it was shown that the pipe material during underground operation does not undergo significant changes in its initial characteristics. At the same time, it was noted that the pipe grades of polyethylene raw materials of the first generation had low resistance to slow crack growth, therefore, the presence of internal defects in the pipe material in owning value with the effect of concentrated loads can lead to premature loss of containment. The work carried out confirmed the possibility of a quantitative design assessment of the technical condition of the gas pipeline based on the results of destructive tests of pipes for long-term hydrostatic strength. The experimental data presented in the article are of interest to specialists who are faced with the need for expert assessment of the state of the pipes of the operated polyethylene gas wires and forecasting their service life.

Reinforced Thermoplastic Pipes (RTP; or Flexible Composite Pipes) are multilayered pipes that consist of inner, outer polymer shell and reinforcement layers. Although there are different types of reinforcement, due to widespread use in oil gathering systems in Russia, we consider steel strip reinforced pipes in this paper. While developing RTP manufacturers state constructive characteristics after conducting analytical analysis and experimental investigations. Final characteristics values are then published in technical regulations documents. Deviation from these values weaken strength of pipeline.As a result of conducted research it was shown that a thinning of a reinforcement strip by 0,1 mm leads to decrease in a burst pressure by 16 %. Similar effect on the pipe reliability has a deviation of the winding angle.

The article is devoted to the use of regression analysis to analyze the use of biopolymer reagents based on gums of various manufacturers — domestic reagent brand KK (Russia), foreign Kem-X (USA) and Rodopol-23R (France).The use of these reagents in the composition of drilling fluids (BR) leads to the fact that BRs exhibit pseudoplasticity properties that are necessary for accident-free passage of multi-meter horizontal intervals and qualitative penetration of productive zones at various fields in Russia, including those in the Volga-Ural region. Equations of dynamic shear stress (DPS) and effective viscosity (EV) were obtained depending on the concentration of the examined gum (biopolymer reagent) and shear rate. The effectiveness of various gums (biopolymer reagents) and comparative analysis of the regression equations of the main parameters of drilling fluids using these reagents were evaluated.

The operation of most chemical processes is accompanied by the cooling of various production streams over a wide temperature range using various refrigerants. At cooling temperatures of process streams up to 25 °C, the most common refrigerant is water prepared in circulating water supply systems of petrochemical plants equipped with fan cooling towers, the work of which is considered in the article. Operation of open cooling towers in single-circuit cooling systems is characterized by high economic efficiency with a wide range of thermal capacities. However, drip entrainment of circulating water, entry of production products into the atmosphere, enrichment of circulating water with oxygen followed by growth of microorganisms in water requires a transition to two-circuit systems in which cooling is carried out by a closed-cycle refrigerant cooled by open-cycle water passing through cooling towers. But such changes in cooling systems reduce the economic efficiency of these systems. The analysis of the equipment operation in the open and closed circuits of the cooling system, provided that a number of system parameters are constant (heat load, quality of purification of recuperation heat exchangers of the cooling system, etc.), made it possible to formulate optimization (minimization) of operating costs for water cooling. Taking into account the previously obtained models of pollution growth in recuperation heat exchangers and considering the vector of control parameters of the optimization problem, the main parameter of optimization (mimimization) of operating costs for cooling, which is the cooling temperature of cooling water, was identified. The results of the analysis of the influence of ambient air parameters on the temperature of the produced cooling water in the open cooling towers are also presented, and the calculation of the economic efficiency of the cooling system operation is carried out taking into account seasonal changes in ambient air parameters.

Rotating machines are an important and crucial component of numerous mechanical systems in modern industry, vehicles and a number of other applications. Excessive vibrations on rotating equipment due to numerous faults can lead to machine failures and lead to accidents. Thus, there is a need to understand the dynamic nature and identify faults for safe, uninterrupted and efficient operation of machines. This paper proposes a new approach to assess misalignment in a test using the same concept as in an imbalance test when balancing the rotor of high-speed machines in the oil and gas industry. The misalignment of the active magnetic bearing with the rotor was investigated. To accomplish this methodology, a four-degree-of-freedom dynamic model of an unbalanced and misaligned rigid rotor and two offset disks supported by two active magnetic bearings was mathematically developed. Disks with displacement lead to a gyroscopic effect at high rotor speeds. The equations of motion of the rotor-bearing system were derived and solved in order to obtain a displacement of the rotor in the time domain and control the current responses in the positions of the magnetic bearing. The algorithm for identifying the estimation of the unbalance and misalignment parameters of the active magnetic bearing was carried out by using the fast Fourier transform method. The effectiveness of this method was estimated at rotor speeds from 100 to 350 rad/s. In the process of determining the efficiency, random modeling errors of 1, 2 and 5 % were also introduced to the mass of the rotor and the moment of inertia of the disk.

Also, the program implements the possibility of organizing multivariate calculations with enumeration of parameters. As a result, all options are calculated automatically and the option with the maximum NPV is selected. The cost indicators of surface facilities are calculated on the basis of comparable cost estimation using the Lenz formula. Implemented automatic filling of calculation results in the economic model of the Company.For the operation of the module a geological, capital cost and technological database of analogue objects has been formed based on data of implemented development projects of gas and gas condensate fields. The article presents the results of an express assessment of a licensed area with gas deposits in the «Feasibility study system» module. The comparison with the results of the previously approved investment memorandum is given.The calculation module «Feasibility study system», implemented in the «RN-KIN» software package, makes it possible to improve the quality of decisions about involving into development of fields, to develop the most optimal strategies of the development of acquired and commissioned deposits. Automation of the calculation process can significantly reduce labor costs for the feasibility evaluation.","PeriodicalId":9748,"journal":{"name":"Chemical and Petroleum Engineering","volume":"13 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90276181","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}

Generation of cold is great demand process for many enterprises of the oil and gas industry. With large capacities of the enterprise, deeper cooling of heat carriers is required in chemical and petrochemical industries, metallurgy, compressor stations, etc. In administrative buildings and workshops located on the sites, it is required to create comfortable conditions in the buildings for the people who are there. In this regard, the demand for refrigeration units is increasing. Until recently, steam compression refrigerating machines were the market leader in refrigeration units. However, their main disadvantage is the high consumption of electricity, and often the process of generating cold has become too expensive.Relatively recently, steam compression refrigerating machines (chillers) have been replaced by absorption refrigerating machines (ARM). Their main and key feature is that they generate cold without consuming a single kilowatt of electrical energy, since the process of generating cold is based on the thermophysical properties of low-boiling solutions of lithium bromide or ammonia.

For a long time, associated petroleum gas was considered a by-product of oil production. Its properties were underestimated and most of the extracted raw materials were burned. However, the development of the gas and petrochemical industry has made it possible to take a fresh look at the possibilities of using associated petroleum gas: the extraction of valuable products from it using hydrocarbon processing technology. Currently, each oil producing company adheres to the approach to the rational use of associated gas, which is based on its use as a feedstock for obtaining valuable hydrocarbon products. In this regard, there is a growing need to carry out technical and economic feasibility for projects to extract target liquid hydrocarbons from associated petroleum gas.The article outlines the difficulties in applying the traditional approach to the implementation of technical and economic feasibility for projects to extract target liquid hydrocarbons from associated petroleum gas and natural gas in large fields with developed infrastructure. The need to develop a new, more efficient methodology for conducting technical and economic feasibility of such projects in terms of reducing the time and cost of work is indicated.The authors proposed a methodology for creating a software tool for conducting an express technical and economic feasibility on the extraction of target liquid hydrocarbons from associated petroleum gas and natural gas. This methodology will allow in a short time and at minimal cost to rank and select the most attractive projects for further full-fledged technical and economic feasibility and exclude work on conducting a technical and economic feasibility of obviously unprofitable projects.
