The paper describes the results of aerobic-peroxide catalytic oxidation of naphthalene in the presence of iron-containing multi-walled carbon nanotubes Fe@MWCNT. The active nanocarbon substrate containing α-iron atoms and carbides realizes by the Fenton reaction active formation of active particles and intensive oxidation of the hydrocarbon under rather mild conditions. It was found that at the temperature range 333 - 353K, in the presence of hydrogen peroxide (30% aqueous solution) and Fe@MWCNT (Fe ≈3.7 wt. %), under intense air current, the reaction proceeds without destroying the cyclic structure of the molecule with predominant formation of phthalic anhydride and naphthol. Identification of the functional groups of the main target products was performed by the infrared (IR) spectroscopy. The results obtained can be proposed for further development of such studies and bringing them into compliance with the standards of the industrial process. Keywords: aerobic oxidation of hydrocarbons; oxidation of naphthalene; hydrogen peroxide; multi-walled carbon nanotubes; nanocarbon catalysis; Fenton system, oxygencontaining aromatic compounds.

The reaction rate constant is a powerful tool for improving the efficiency of acid treatments, which is used both for selecting optimal acid compositions and for mathematical modeling. However, there are still no unified methods and tools for its determination, which leads to low reproducibility of experiments and difficulties in interpreting the results. To improve the processes of studying the kinetics of the reaction of acid with carbonate rock, together with AO "Geologika", a volumetric installation "PIK-OSG" was designed and manufactured, a special algorithm for processing data was developed. A series of test experiments were carried out, a method was proposed to reduce the error by pressing the disintegrated core into tablets. Keywords: acid treatments; reaction kinetics; reaction rate constant; volumetric setup; laboratory studies.

At the present stage of the development of the oil industry, mathematical modeling is widely used in the design and analysis of development during the entire cycle of field operation. The most laborious and difficult stage in the creation of geological and hydrodynamic models is their identification to the actual development data and resolution of uncertainties associated with the analysis of geological and physical parameters. Parametric identification is the most important procedure in the modeling process, because the degree of reliability of predictive indicators of object development depends on the quality of the results obtained at this stage. The paper presents the main methods and results of adapting the hydrodynamic model in the history of oil field development in order to use the model to calculate forecast options. When creating a geological and hydrodynamic simulation model for the selected block of the Kenkiyak deposit of Kazakhstan, geological and field data and research data on the determination of thermobaric parameters of fluids and rocks were used. To solve this problem, the Masket-Meres model of isothermal unsteady spatial filtration of reservoir fluids was adopted. The desired parameters are refined on the basis of gradient procedures using optimal control theory. The predictive problem of the feasibility of using horizontal wells to increase the oil recovery coefficient of the specified sector of the field has been solved. Keywords: adaptation; predictive task; oil recovery; oil reservoir; phase permeability; hydrodynamic model.
在石油工业发展的现阶段,数学建模被广泛应用于油田作业全周期开发设计与分析中。在建立地质和水动力模型的过程中,最费力和最困难的阶段是对实际开发数据的识别,并解决与地质和物理参数分析有关的不确定性。参数识别是建模过程中最重要的步骤,因为对象发展预测指标的可靠性程度取决于此阶段所获得结果的质量。本文介绍了油田开发历史上采用水动力模型计算预测方案的主要方法和结果。在为哈萨克斯坦Kenkiyak矿床选定区块建立地质和水动力模拟模型时,使用了地质和现场数据以及流体和岩石热压参数确定的研究数据。为了解决这一问题,采用了储层流体等温非定常空间过滤的Masket-Meres模型。利用最优控制理论,在梯度过程的基础上对所需参数进行了细化。解决了水平井提高油田指定区段采收率可行性的预测问题。关键词:适应;预测任务;采油;石油储层;相渗透率;水动力模型。

A method and device are proposed for implementing SWAG injection by pumping a water-gas mixture. The proposed technical solution will allow to regulate and measure the flow rate of the mixture injected into each injection well. At the same time, the technology contributes to an increase in oil recovery. The device for implementing the technology makes it possible to withdraw associated gas from the annulus of production wells, which helps to reduce pressure below critical values and prevent disruptions in the supply of well products to the pumps. The device contains diaphragms - measuring devices for controlling the flow of water-gas mixtures, which are injected into selected injection wells by means of booster pumps. Keywords: water-gas mixture; pumping-ejector system; SWAG technology; liquid-gas ejector; pressure-energy haracteristics of ejectors; diaphragm.

Article presents an overview of studies of the gas bubbles interaction processes in the composition of water-gas mixtures. Data are given on theories that indirectly indicate the nature of the phenomenon of coalescence, or its suppression. It has been established that there are rational ranges of parameter values at which coalescence suppression is observed, however, when some critical values of these parameters are exceeded, the coalescence suppression regime breaks down. The experimental studies of the gas flow rate effect, passed in the bubbles flow form through a column with liquid, at various pressures and salinity of the liquid showed that an increase in the maximum gas flow rate with suppressed coalescence is observed in a certain range of salinity (with increasing pressure). However, further with an increase in salinity, the maximum the gas flow rate remains constant, after which the regime breaks. The addition of foaming surfactants increases the maximum gas flow rate. At the same time, a study of multistage centrifugal pump characteristics showed that the addition of surfactants improves the performance of the pump up to a certain concentration, with an increase in this concentration, the performance improves slightly. A further direction of studying the technology of creating stable water-gas mixtures is also formulated. Keywords: carbon footprint reduction; SWAG technology; pump-ejector systems; water-gas mixture; coalescence of gas bubbles.
本文综述了水气混合物组成中气泡相互作用过程的研究概况。数据给出的理论,间接表明性质的聚结现象,或其抑制。已经确定了聚结抑制存在合理的参数值范围,但是当超过这些参数的某些临界值时,聚结抑制区就会被破坏。实验研究了在不同压力和盐度条件下,以气泡形式流过含液柱的气体流速效应,结果表明,在一定盐度范围内(随着压力的增加),气体最大流速增加,聚结受到抑制。然而,随着矿化度的进一步增加,最大气体流速保持不变,之后该状态被打破。泡沫表面活性剂的加入增加了最大气体流速。同时,对多级离心泵特性的研究表明,表面活性剂的加入在一定浓度前对泵的性能有改善作用,随着该浓度的增加,泵的性能略有改善。提出了进一步研究形成稳定的水气混合物技术的方向。关键词:碳足迹减排;赃物技术;pump-ejector系统;水煤气的混合物;气泡的合并。

The region’s oil fields are located within the South Caspian oil and gas basin, on the territory of the Absheron Peninsula and the adjacent waters of the Caspian Sea. Here are more than 80 oil and gas fields. To this end, this article presents the geological structure of the South Caspian Depression, as well as the Absheron-Balkhan zone. The analysis of oil and gas content and modern seismicity of the Caspian Sea is carried out. Increasing recoverable oil reserves, reducing water cut, increasing or even stabilizing production at this stage is the number one task for the oil industry. It has been established that in recent years, the level of seismic activity of individual sections of the Caspian water area has increased, and the amount of seismic energy released in the Central Caspian has increased by several dozen times, it can be assumed that the change in oil production in many offshore fields in the northern part of the Absheron-Balkhan fold system is associated with strong (ml>3.0) earthquakes characterized by fault-shear type of movements. Keywords: Caspian sea; oil and gas deposits; earthquake source mechanisms.
该地区的油田位于南里海油气盆地内,位于阿布歇隆半岛和里海邻近水域。这里有80多个油气田。为此,本文介绍了南里海坳陷以及阿布歇龙-巴尔汗带的地质构造。对里海的油气含量和现代地震活动性进行了分析。现阶段,增加可采储量、降低含水率、增加甚至稳定产量是石油行业的首要任务。近年来,里海水域个别剖面地震活动水平有所增加,里海中部地震能量释放量增加了几十倍,可以认为,Absheron-Balkhan褶皱体系北部许多海上油田的石油产量变化与以断层剪切型运动为特征的强地震(ml>3.0)有关。关键词:里海;油气矿床;震源机制。

The article deals with the problem of risk assessment in the design of the construction of plants and shops for the production of fittings in the metallurgical industry. For the researcher, a classification of risk assessment methods based on the completeness of the available data is presented. In essence, generalized modeling methods, statistical method, sensitivity analysis method, tree decision method, expert method and approaches based on fuzzy logic were used. A more detailed description of the assessment of environmental risks by a method based on the use of fuzzy logic is given. Keywords: risk factors; environmental risks; risk assessment; fuzzy logic.

Laboratory Information Management Systems (LIMS) are powerful tools for improving the efficiency of modern laboratories. They are very popular in laboratories due to the presence of a large flow of samples and have the widest functionality – from identifying measurement errors to accounting for stocks. At the same time, redundant tools lead to an increase in the cost and increase of implementation of LIMS. To meet the needs of customers, was started the development of a new LIMS as a client-server web application, available on any device with Internet access. New LIMS will increase the functionality of research laboratories in the oil and gas industry, as well as the process of its implementation is not particularly difficult. Keywords: laboratory information management system; information management; research laboratories; laboratory processes control.
实验室信息管理系统(LIMS)是提高现代实验室工作效率的有力工具。由于存在大量样品流,它们在实验室中非常受欢迎,并且具有最广泛的功能-从识别测量误差到计算库存。同时,冗余的工具导致成本的增加和LIMS实施的增加。为了满足客户的需求,我们开始开发一种新的LIMS,作为客户机-服务器web应用程序,可以在任何具有Internet访问的设备上使用。新的LIMS将增加石油和天然气行业研究实验室的功能,并且其实施过程并不特别困难。关键词:实验室信息管理系统;信息管理;研究实验室;实验室过程控制。
