The article is dedicated to methods for estimation of efficiency of operating low production well stock equipped with ESP. Based on the results of bench tests of high-speed ESP and comparing with field data, adjusting coefficients of efficiency were determined and functional relationship of energy characteristics on the motor’s shaft speed, the obtained correlation proposed for recalculation of passport value to bench ones.

PJSC TATNEFT is implementing a program to optimize production and reduce its own costs. Reducing the cost of operating onshore oilfi d equipment is one of the most important tasks under the program. This article describes a method to increase the turnaround time of pumping units for pumping the produced liquid by upgrading equipment.
The purpose of this work is developing a computer model of steam ejector for oil heating, oil product pumpout, and performing of other key functions in the oil and gas industry ANSYS Fluent is applied. To achieve this purpose a procedure is used including a computational mesh adaptation algorithm, a selection of the turbulence model, a determination of the optimal settings of Fluent problem solver, an assessment of the accuracy of the results. Based on the results of the computations made, the model is verified using experimental data and a dependency of the basic parameters of its work is studied. The article includes a description of the recommended settings for the Fluent problem solver for the engineering computations of the jet devices.
Well known that pumps pumping abrasive liquids have a short lifetime. Laminar pumps (disk pumps), produced in Russian Federation, are able to pump high viscosity clean and abrasive liquids. Application of the laminar pumps could increase lifetime and reliability, decrease maintenance costs and labor works, improve technology process. The laminar pumps even could improve the quality of a pumping liquid during maintenance. Constructions and different applications cases of the laminar pimps are given in this article.
Article presents factors analysis results, influencing power characteristics and service life of the pumping system. The description of the new design rubber-metal stator, reinforced by metal inserts, drive shaft and pump unit protecting device against adverse gas impact during liquid phase low fraction medium pumping or at absolute liquid phase absence (“dry running”) pumping are also presented.
The paper discusses the main achievements in the field of automation control systems for quality and efficient decision-making on the state of theoil-producing plants, which is a key element of diagnosis, which is of great value for neftyantedobyvayuschey industry.
AbstractThe article presents main trends for reducing power consumption in oil gathering system and demonstrates that power consumption costscan be reduced using multi-phase technologies. The pilot test results are shown to assess the feasibility of replacing the dynamic pumps to less power consuming positive displacement pumps. The conclusions are made with regards to possible utilization of positive displacement pumps in the oil gathering system.
Article about centrifugal pumps for the oil refining, petrochemical, mining, steel, pulp and paper, power, cement industry, as well as for pumping waste water in municipal, industrial and agricultural water supply. And in terms of pumping equipment article describes information about traditional oilpumps of the (1.2) NC, (1.2) NPS, NSD-E type. Also in the article we describe theproduction of a new design oil pump 2NKand 2NPS type, which Conform to the requirements of API 610.
At present time the amount of light oil in our country decreases, and the share of more viscous and heavy oil from total amount of production becomes more and more. In this article influence of viscous liquid on performance of the electrical submersible pump (ESP) is considered. As at operation of the electrical ubmersible pumps operating staff know only the pump performance during the work on water, they should make recalculation of pump performance taking into account conditions at which the pump will work. Comparison of the recalculating factors received experimentally and theoretically by a methodology of P.D.Lyapkov which is taken as a basis at many companies of oil industry.
AbstractThe problem of corrosion resistance of the working surface of the cylinders of oil-well sucker-rod pump is one of the most actual problems in the operation of pumps in corrosive well. Without high resistance to corrosion in the cylinder wells produce its resources much earlier than the consumer expects it. In order to extend the "life" of the nitrided cylinder of oil-well sucker-rod pump, save on the surface layer of a high-corrosion properties. The paper presents a methodof improving the corrosion resistance of the working surface of the cylinders of oil-wellsucker-rod pump by ion-nitriding vacuum to form a nitride zone.
In this work results of research hydraulic characteristics of the return valves intended for transfer special liquids abroach are presented. The task of search hydraulic characteristics of valves are decide with special methods of mathematical modeling with application of packets applied programs and by engineering calculations with application of reference books on the basis of the approved engineering methods of calculation. In work the methodology of determination economic benefit is presented at use slide valves instead ball, allowing to estimate a difference in costs of resources at comparison work valves of various types.
The main problems are analysed, that are associated with oil slime handling and analysis of their toxicity to humans and the environment. The peculiarity of the authors approach - a comprehensive analysis of potential impacts of sludge on the environment with regard to their migration and transformation in their contacts with components of the environment. The priority areas for improving the regulatory framework for the regulation of the impact of sludge on the environment are identified.
On the basis of available development of science and industrial experience in the field of manufacturing production with accurate dimension hardened highly loaded surfaces at operation by working by methods nanotechnology ion-vacuum pulse nitriding to increase manufacture let out and to master new products of oil production and drilling equipment, to expand using new IVP-technology in various branches mechanical engineering.
