Downhole sucker-rod pumping units remain one of the main types of oil production equipment: these units operate in more than 50 thousand wells in Russia.

A significant number of all failures (from 24 to 60 %) of sucker-rod pumping units occur with sucker-rod pump valves small and low-cost components. The use of appropriate design schemes and correctly selected materials can significantly increase the reliability of the valves and the entire sucker-rod pumping unit as a whole.

The results of bench tests and numerical experiments are presented. They made it possible to identify the best designs of valve assemblies, optimal materials for manufacturing balls and seats and to determine rational applications of valves made of different materials.

 

Keywords: sucker-rod pumping unit; sucker-rod pump; valve; ball; seat; tightness; operational time prior failure.

A significant part of the Cenomanian deposits that are unique and the largest according to classification of the Far North fields reserves, such as Yamburgskoye, Urengoyskoye, Medvezhye, Yamsoveyskoye, Yubileinoye, Komsomolskoye, Vyngapurovskoye, etc., are in the stage of decline of natural gas production. The gradual depletion of the deposits reserves and a significant drop of the reservoir pressure changed the temperature and pressure parameters of natural gas and increased its moisture content and, as a result, the liquid load increase on the integrated gas treatment plants (IGTP). This fact, in turn, changes the conditions and, in some cases, the efficiency of inlet structures operation (gas purification separators), gas compressing units, a glycol regeneration system and subsequent gas treatment equipment.

Due to the high content of the liquid phase, passing with the gas, gas purification degree of inlet separators is less than that of the original technical characteristics, causing withdrawal of droplet liquid above the standard values, determined for gas production facilities of PJSC "Gazprom" in accordance with the requirements of STO Gazprom 2-2.1-588-2011 "Standard technical requirements for technological equipment for gas production facilities".

As known, separators operational efficiency depends on the design of the internal devices, on the assembly of the plates fillers, the design special features of the elements, mesh irregular or centrifugal direct-flow and their location on the separation plate. The main indicator is the quantitative withdrawal of droplet liquid with gas from a separator.

The presented paper assesses the advantages and disadvantages of centrifugal mass transfer elements with mesh separation elements and also demonstrates graphical dependencies and boundaries of the separation efficiency of the centrifugal elements work.

The paper also analyzes the design features of centrifugal mass transfer elements of various constructions that were subjected to industrial tests in inlet separators at the gas fields of the Yamburgskoye and Yubileinoye fields.

Based on the results of the analysis of the structures of mass transfer elements, it can be concluded that there occur liquid droplets fragmentation into a finely dispersed fraction due to the pulsation of the incoming gas flow through the direct-flow centrifugal elements, which are not able to catch liquid droplets of less than 10 microns in size, presence of the secondary withdrawal as a result of liquid droplets crushing as well as uneven distribution of the gas flow inside the apparatus due to the so-called "shadow zones", which are formed in the cross section on the separator plate. They include peripheral (extreme) centrifugal elements, which receive a low gas flow rate, which reduces the flow rate (weak swirl) and, accordingly, the separation efficiency of these elements decreases. Adaptation to the current operational conditions requires application of new technical solutions for the design of centrifugal mass transfer elements to ensure the initial requirements for gas separation.

 

Keywords: centrifugal mass transfer element; gas separation; separation equipment; contact devices; regular nozzle.

The paper presents the results of determining the geometric parameters of the main working elements of the bearing assemblies of roller-cone drill bits with a controlled lubricant supply system. As a result of the research conducted, computational methods were developed and criteria were established for assessing the choice of the main design parameters of the lubrication system of sealed oil-filled bearings with controlled supply of lubricant for roller-cone drill bits, including the required amount of lubricant, taking into account a given technical resource, volumes of the oil reservoir and hydraulic accumulator, dimensions and configuration of oil grooves. The proposed methods for effective control of the lubrication system in the process of pumping lubricant into the support units, as well as during the operation of a roller-cone drill bit are proposed.

The paper considers the aspects of quality management during drilling operations. It is shown that the objects of drilling quality control are wells and drilling technological processes. Wells quality management is implemented through strategic and operational management. Strategic management of drilling quality should be carried out in relation to all stages of a well life cycle using an end-to-end quality management system (subsoil user, contractors, suppliers), application of competitive selection procedures for contractors and suppliers, and various forms of conformity assessment. A well is a mining facility, so its quality metering of its mining and technical components should be carried out in the quality management system. From the point of view of wells functional purpose, their quality, in the general case, can be represented as a set of properties and the corresponding complex indicators: functionality, reliability, safety and resource intensity.

 

Keywords: wells drilling; wells quality; quality management in drilling; environmental management; occupational safety and health management.

The article considers the problems of operation of gas production wells of the Cenomanian deposit of the Urengoy oil and gas condensate field at the final stage of development, which includes the intensive removal of the associated sand-liquid mixture with the gas phase. For field separation of natural gas from liquids and solids, a technically developed wellhead device is proposed, which is structurally implemented in a factory design. It was also noted that the efficiency of a wellhead separation can be ensured during a low-temperature operation of the device by supplying methanol or additional thermal insulation of the equipment. In addition, the article describes the possible methods of the separated liquid disposal, and also outlines the prospect of studying the dynamics of the separation processes of the near well head separator in order to increase its efficiency.

Injection of isolating sodium silicate-based compositions with controlled gel time is regarded as one of the promising trends among the variety of water control technologies. TatNIPIneft engineers have developed a novel water shutoff technology that uses sodium silicate-based compositions with controlled gel time. Water shutoff effect is provided by plugging water-yielding zones by an acid-resistant gel injected into the trouble zone. Tests to determine optimal concentration of the components making up the water shutoff composition showed that by changing the content and the concentration of components gelling time can be increased from 2 to 30 hours, yield strength can be increased from 48,2 to 995 Pa. A routine technology is used to make up the composition in field. A pilot project is underway. Up to now, water shutoff jobs have been performed in three wells; the technology efficiency is now evaluated.

Rational development of oil and gas fields includes both a substantiated development system and the selection of the optimal energy supply system for the oil and gas production. A competent choice of a power supply system requires a technical and economic comparison of various energy supply schemes, the selection of technological equipment, as well as accounting for the use of associated gas within the environmental constraints. The world is currently aiming at the most environmentally friendly sources of energy for power supply of oil and gas production enterprises, especially in the fields, remote from infrastructure and being in harsh climatic conditions. The paper summarizes the Russian and world experience of the last five years in the use of various types of energy systems in terms of power supply of production complexes in difficult conditions. The analysis showed that it is promising to use power plants based on renewable energy sources (renewables) at such fields.
