The problem of carbon dioxide utilization is of increasing concern to the public, since measures to reduce greenhouse gas emissions are no longer sufficient to prevent a global increase in temperature on the planet. The global energy sector is facing two major challenges: skyrocketing prices for petroleum products and an increase in the amount of carbon dioxide emitted into the atmosphere by industry. The growing anthropogenic pressure on the environment has increased interest in the geological storage of carbon dioxide. Developments in the field of alternative energy sources are becoming more and more relevant: hydrogenation and synthesis, solar energy, hydrogen energy. Promising trend, from the point of view of utilization, is associated with the production and use of environmentally friendly energy carriers through the conversion of carbon dioxide. The article discusses modern technologies for producing hydrogen and industrial conversion of carbon dioxide into useful products, including the author's nature-like method for converting carbon dioxide into green energy resources. Keywords: carbon dioxide utilization; underground storage; hydrogenation and synthesis; hydrocarbons; hydrogen; alternative energy sources; catalysts.

In the work, a dependence was obtained, analyzing which it is easy to see that the dimensionless parameter of sticking hazard depends very significantly on the permeability of the reservoir and increases in proportion to the increase in pressure drop, which is fully confirmed by the results of numerous experimental studies of sticking under the action of pressure drop. At the same time, one of the main, but previously not taken into account, factors that contribute to the occurrence of sticking in drilling wells is the viscosity of the formation fluid, as it decreases, the dimensionless sticking hazard parameter (i.e., the possible sticking force) in the interval of occurrence of a given permeable formation increases sharply. Indeed, the experience of drilling operations in various regions indicates that when drilling wells in gas fields, the frequency and severity of sticking is much higher than when drilling wells in oil fields, this requires special consideration in the process of drilling wells in gas fields. Keywords: sticking; drilling and casing strings; differential pressure; filter cake; viscosity; formation fluid.

The article discusses some of the main criteria that determine the size of reserves in hydrocarbon fields. It is noted that large-scale oil and gas accumulation is possible in natural reservoirs that meet certain conditions. Reservoirs with good characteristics, in the presence of a powerful source of replenishment of hydrocarbons, can form larger deposits with sufficient trap volumes in the natural reservoir. With a homogeneous reservoir with high characteristics, the distribution area of hydrocarbon accumulation can be more concentrated. Heterogeneous reservoirs more often generate hydrocarbon accumulations scattered over the area. Using the example of unique and large deposits in the junction zone of the Yenisei- Khatanga regional trough with the West Siberian depression, a dependence with a high correlation coefficient between the value of hydrocarbon deposits and the effective volume of the trap, which is determined by the effective thickness of the reservoir and the area of distribution of the trap in the natural reservoir, was obtained. In the area of the Vankorskoye , Tagulskoye and Vostochno-Messoyakhskoye fields, the collectors of the Yakovlevskaya and Nizhnekhetskaya formations with the highest oil and gas saturation have the maximum effective capacity and distribution area. Keywords: collector; trap; effective volume; natural reservoirs; large-scale oil and gas accumulation; hydrocarbon reserves.

Sustainable development of organizations implies stable socio-economic development without disturbing natural ecosystems and improving the quality of people’s lives, taking into account the economic capacity of the biosphere. The article considers the stages of implementation of integrated management systems on the example of a fuel company. Integrated management systems are essential to the efficient and sustainable operation of an organization. Integrated management systems include two or more international standardized management systems in the field of environmental protection, industrial safety and labor protection. These management systems are interconnected and operate in organizations as a single system. The paper shows the benefits for the organization when using integrated management systems based on the requirements of the ISO 14001 Occupational health and safety management systems and ISO 14001 Environmental Management Systems standards. Emphasis is placed on innovations in ISO 14000:2015 standards. Methods for determining the opportunities and risks of an organization in the field of industrial safety, labor protection, and the environment are shown.

In gas condensate fields, low-temperature separation process is mainly used for primary processing of gas. Cooling of well products in gas preparation systems is achieved by throttling them. As the reservoir pressure decrease, the amount of energy obtained decreases. This worsens the conditions for the preparation of gases. Therefore, raises a need to use additional energy sources. Analysis of the operating modes of gas treatment plants has shown that the energy obtained during the expansion of gas can be used rationally. Calculations have shown that the gas temperature at the outlet of turbodetander units during adiabatic expansion provides the required dew point for water and hydrocarbons. Keywords: gas; condensate; turbodetander; gas expansion; polytrophic; adiabatic; cold productivity; dew point.

Article focuses on the improvement of the technologies used to improve the durability of friction pair components. The authors use the piston compressor to study cellular microrelief surfaces of cylindrical components. The cells are shaped as elliptic paraboloid with uneven positive parameters. The use of cellular microrelief surfaces is highly preferred as they reduce the attrition wear of the friction pairs through assuring the hydrodynamic load capacity of the lubrication layer with the shape of the microrelief. The research goals included the parametric analysis of the lubrication layer behavior in the gap between the microrelief cells. To do this, the authors developed an analytical model based on the theory of hydrodynamic lubrication and constructed a CFD model using the ANSYS Fluent software. To contain the transfer equations, the authors used the turbulence model SST k–ω. Both models showed that the maximum hydrodynamic load capacity coincided with the 75%-length of the major axis of the elliptic cell, which also corresponds to 0.128 mm in cell depth. The maximum lifting hydrodynamic pressure on one microrelief cell amounted to 3 kPa. Based on the results of the parametric analysis, the authors claim that the cellular microrelief can be efficiently used to assure the service properties of friction pairs in process units. Keywords: friction pair; cylinder sleeve; piston ring; cellular microrelief; hydrodynamic model; mathematical model; ANSYS Fluent; two-dimensional parametric analysis.
文章重点介绍了提高摩擦副部件耐久性的技术改进。利用活塞式压缩机对圆柱构件的微凸面进行了研究。细胞呈椭圆抛物面形，正参数不均匀。蜂窝微浮雕表面的使用是非常可取的，因为它们通过保证具有微浮雕形状的润滑层的水动力载荷能力来减少摩擦副的摩擦磨损。研究目标包括对微缓动单元间隙中润滑层行为的参数化分析。为此，作者基于流体动力润滑理论建立了解析模型，并利用ANSYS Fluent软件构建了CFD模型。为了包含传递方程，作者使用了湍流模型SST k -ω。两种模型均表明，最大水动力载荷能力与椭圆池长轴长度为75%时一致，对应池深为0.128 mm。一个微泄压池的最大提升动水压力为3 kPa。基于参数分析的结果，作者认为单元微位移可以有效地用于保证过程单元摩擦副的使用性能。关键词:摩擦副;汽缸套;活塞环;细胞微地貌;水动力模型;数学模型;ANSYS流利;二维参数分析。
