Analysis of sucker-rod pumps chain drives during wells operation has demonstrated that about one half of chain drives failures is caused by the inadmissible chain pull as well as wear-out failures of the chain sprockets. The problem salvation requires periodic manual adjustment of the chain tension during operation. TatNIPIneft Institute of PJSC "Tatneft" proposes perfection of chain drives constructions of wells sucker-rod pumps that will provide reliability and longer service life due to automatic maintenance of the set chain tension of the converting mechanism. Some options of the chain tension by the motion of the lower driving sprocket due to the intermediate frame replacement as well as at the expense of the upper driving sprocket replacement by the weight of the load, using the diamond-shaped electrically-driven jack and the hydraulic jack with the drive from the transforming mechanism. Adjustment of the chain automatic tension of the transforming mechanism will provide reliability increase and durability of chain drives operation when using tension chains, made in Russia.

 

Keywords: chain drive; pulling chain; construction; automatic maintenance of chain tension; reliability and durability of operation.

The article proposes a method of evaluation of metal structures’ welded joints durability at the objects of oil and gas producing complex based on accelerated testing. This approach is based on a large amount of experimental data processing, given in the scientific works of domestic and foreign researchers, which resulted in established a connection that provides determination of effective coefficient value of welded joints concentration with account of their main construction-geometric parameters.

The values of stress concentration coefficients Kσ in the samples used during accelerated tests by means of their recalculation when determining the value of the efficient coefficient of stresses concentration, can be calculated by applying the well-known methods for various types of concentrators, that have complicated geometrical shapes, and load schemes.

The developed approach allows to essentially reduce the time of testing the welded joints endurance as compared with the standard testing. The method provides accounting of the constructive-technological parameters of metal structures welded joints at the objects of an oil and gas producing complex when evaluating their durability.

 

Keywords: welded joints; durability; accelerated testing; endurance limit; stress concentration.

Natural gas is one of the most important energy carriers in the world. Arriving from wells, already at the field it goes through several stages of primary processing, that changes its qualitative basis. The presence of moisture in gas reduces the reliability of the technological systems, increases the likelihood of emergencies, so natural gas supplied to the gas pipeline is subjected to mandatory drying from moisture. The depth of drying is determined by the requirements of industry standards. The method of gas drying, the most popular in practice, is absorption, carried out by means of nozzle absorbers.

The paper presents a constructive scheme of a packed absorber with its technical characteristics, analyzes the normative-technical documentation, standards. This made it possible to determine the main qualitative characteristics of the object, such as the tightness of its construction, the quality of welding seams as well as to diagnose its strength characteristics from the conditions of the maximum permissible wall thickness of the absorber.

The conducted researches provided development of a certification test method for a packed absorber for drying natural gas at a field.

 

Keywords: natural gas; gas drying unit; quality; standard; certification.

The contemporary period of oil production is characterized by reduction of oil reserves portion in porous reservoirs relative to that of simple structure. To restore hydrocarbons resource base, hard-to-recover oil reserves are involved into development, the production of which was earlier complicated by different reasons. Formation heterogeneity characteristic of complicatedly-composed reservoirs is one of those difficulties. Modern standard methods of filtration studies are not effective for modeling complicatedly-composed reservoirs with high heterogeneity. To solve this problem, a new method applied to test the technology of enhanced oil recovery, water shut-off and oil displacement in complicatedly-composed carbonate reservoirs, following in appropriate conditions, was developed. To research filtration processes in reservoirs conditions, Autoflood-700 installation developed by "Vinci Technologies SA" was used.

The problems of particles deposition from an oil disperse system come to determination of particles flow on the surface, the rate of deposition and the calculation of the deposited layer thickness. Depending on the nature of the process, the particles from the flow are deposited either by diffusion or by gravitation in the free volume. In the case of the diffusion transfer to the surface, the cross-section of the deposited layer is symmetrical, and in case of gravity, the layer of particles on the surface is characterized by an asymmetric profile, i. e. the thickness in the bottom of the pipe is much greater than in the ceiling part. In case of the flow intensive turbulence, due to the high values of the turbulent diffusion coefficient, the cross-section of the deposited layer tends to a symmetrical profile. Various equations are proposed to describe the deposition mechanisms and the obtained models are compared with available experimental data. It is noted that the formation of particles dense layer on the inner surface of pipes has a significant effect on the phenomena of mass and heat transfer.

One of the most urgent problems of design, construction and operation of buildings and engineering structures in the Far North conditions is to provide the stability of their foundations and operational reliability. As a result of thermal and mechanical anthropogenic impact, there occurs a disbalance of the "construction – soils of the foundation" geotechnical system with a significant deformation of natural landscapes and activation of negative geocryological processes for engineering objects, which entail deformation of foundations. One of the most common methods of engineering protection of structures in the cryolite zone is thermal stabilization of foundation soils. The aim of the study is to assess the effectiveness of the devices for temperature stabilization of foundation soils used when constructing and operating production buildings and structures at Urengoy oil and gas condensate field (OGCF). Currently, the algorithm of optimal design-technical solutions and the method of evaluating the effectiveness of applying the technology of thermal stabilization is not fully reflected and studied in the scientific-technical and normative literature. The solution of the problem in relation to operational reliability increase of engineering structures in the cryolite zone using devices for thermal stabilization of soils is a trending topic of research from scientific and practical points of view. To solve this problem, the method of the data statistical analysis, obtained in the course of thermometric measurements was used that revealed the debatable efficiency of thermal stabilizers use, as well as geodetic methods applied to measure deformations of buildings and structures under control. It is revealed that the stability of foundation soils when using thermal stabilizers increases only in case of an individual and technically competent approach to the design and installation of seasonal cooling devices (SCD). Based on the data accumulated during the monitoring, thermal stabilization is not a full guarantee of preventing negative engineering-geocryological processes and with incorrect design and technical solutions can cause their development.

 

Keywords: geotechnical monitoring; permafrost soils; thermal stabilization of soil; seasonal cooling device (SCD).

A standard algorithm of the analysis of the launch facilities technical condition of the main gas pipelines, including offshore gas pipelines, with account of the experience of the Blue Stream (Russia–Turkey) and North-European gas pipeline commissioning is formulated. The limiting factors that should be taken into consideration when calculating the parameters of the gas pumping units are discussed in detail. Recommendations for synchronization of works on testing for strength, cavity drying, conservation by nitrogen and regimes of natural gas filling on the example of the North-European gas pipeline commissioning in the area of "Gryazovets–Vyborg" and Nord Stream offshore gas pipeline.

 

Keywords: natural gas; offshore gas pipeline; pipeline filling with natural gas; quality of gas; reliability; technical condition; gas-compressor unit; testing for strength; cavity drying.
