Automation, Telemechanization and Communication in Oil Industry

Under the conditions of continuous growth of energy prices, optimization and efficiency increase are making new demands on measuring equipment. In this regard, dispersant ejectors are increasingly used for measuring instruments and standards. The paper is devoted to the study of the characteristics of the ejector-disperser installed on the State primary special standard of the unit of mass flow of gas-liquid mixtures GET 195-2011, using numerical modeling methods. The results obtained, which would be almost impossible to obtain experimentally due to the complexity and high cost of the experiment, will allow optimizing the design of the ejector-disperser in future and improve the quality of mixing on GET 195-2011 and standards of similar design.

Keywords: oil and gas mixture; ejector-disperser; numerical modeling; GET 195-2011.

The paper discusses the problems of development of a standard for a mass flow-rate unit of gas-liquid mixtures that meets the requirements of national standards. The materials presented prove the possibility of developing a model in accordance with the theory of similarity existing in the world practice, which makes it possible to create a well – standard pair. The mixture is reproduced in stages. At the first stage, a two-component invariable liquid mixture is created, after mixing with the gas phase, the gas-liquid mixture is reproduced, which, after appropriate mixing, is transferred unchanged to multiphase flow meters. Besides, the problems arising in its main line are considered as well.

Keywords: standard; gas-liquid mixture; well; main line; modeling; reproduction; invariability; transmission; multiphase flow meter.

A method has been developed for determining the required number of LNG-tankers to meet needs of terminals for regasification of liquefied natural gas (LNG). The examples of calculations for different seasons, different distances between the plant for the production of liquefied natural gas (shipment of liquefied natural gas) and terminals for regasification of liquefied natural gas (reception of liquefied natural gas) are given. The technique is recommended for use in automatic control systems for the transportation of liquefied natural gas.

Keywords: liquefied natural gas; LNG-tanker; LNG-plant; LNG-terminal; automated control systems; transport and logistics systems.

The paper proposes a method for choosing the optimal mode of a gas well operation without the formation of a water plug in the wellbore, taking into account the non-equilibrium and nonlinear elastic deformation of reservoir rocks during the period of a gas reservoir development in the depletion mode. This technique allows determining the required current working volume of the produced gas, as well as the well bottom pressure values corresponding to the selected optimal well operation mode.

Keywords: gas field; deformation; pressure; porosity; well flow rate; well bottom pressure; optimal mode.

The paper considers a set of computer modeling programs for obtaining a description of an oil reservoir, based on the proposed methodology. The development of a reservoir description methodology was based on the study and application of geo-information systems that allow modeling processes in the geophysical space. The use of fractals (fractal geometry) and the method of sequential random additions made it possible to obtain intermediate values between wells, information about which was obtained using geophysical probes. The essence of this approach is to find the relationship between the source data and the results of calculations in the form of pseudo values for use in a deeper study of an oil reservoir. Using fractal filtering, one can get pseudo-random values of the source data correlated values, simulating random movement. For the purpose of conducting a more detailed study, Archie and Waxman – Smits models were applied. This approach allowed obtaining: gamma-ray logging, studying the permeability and the lateral cross-section of reservoir layers at different depths. The use of the above-said research methods gives a more detailed study of a reservoir and identifies potential porous rocks.

Keywords: oil reservoir; computer modeling; geo-information systems; fractal; well; pseudo-random addition; gamma-ray logging; reservoir.

The paper considers propagation of stress waves in welded joints in order to assess the concentration of stresses in the weld zone, depending on its geometric and physical parameters. If these temporary stresses do not exceed the yield strength of the material, then by the time of complete cooling the temperature stresses will disappear and residual stresses will not occur.

Keywords: machine parts; welded joints stresses; hydraulic technical facilities; fatigue; strength coefficient.

The paper considers the problem of geo-information system (GIS) technology teaching issues in the context of transition from academic-licensed proprietary software products to free software. The urgency of this transition is caused by the substitution of proprietary products by free software in industrial GIS projects, as well as by the need of organizing online teaching in the University, in particular, during a pandemic. The introduction of free software into the educational process allows students to work proactively and independently, and develop a class project based on open spatial data. At the same time, it is necessary to analyze and modify the existing teaching methods, develop a curriculum, and make a reasonable choice of software tools. Experience proved the effectiveness of a task-based approach to educational process organization, in which a student can independently solve a series of increasingly difficult educational and professional tasks and develop his own class project at the end of the course. This paper proposes a method for software selection. The chosen software should have characteristics that help students develop professional competence. The conclusion is made on the advisability of joint use of proprietary and free software in the educational process. The presented approach was successfully tested as part of the educational process (in particular, online teaching) at the Industrial University of Tyumen, Institute of Geology and Oil and Gas Production, major Information Systems and Technologies.

Keywords: geo-information systems; free software; open GIS; open data; professional education; Q-GIS.
