E-mail: taf@list.ru

 

The problems relating to prospecting and exploration of hydrocarbon deposits in conditions of an arisen sea and directly beneath the ice are discussed in the present article. It is shown that unfavorable climatic conditions prevent conducting geophysical studies not only in the northern, but also in the southern seas within five-seven months in a year.

The following mobile underwater geophysical complex is suggested to be used for hydrocarbons prospecting and exploration: some civil submarine with a nuclear power plant for the northern (Arctic) seas or with anaerobic power plant for the southern seas; two remotely operated underwater unmanned vehicles moving with seismic receivers ahead at a distance of less than 2...3 km and in parallel with civil submarine towing a seismic sensors and carrying a source of elastic vibrations of seismic bandwidth on its body. Moreover, compact (weight kg units), super broad-banded (2…3 octaves) and super directional antennas (units – tens of degrees for remotely-operated and autonomous unmanned underwater vehicles; units and degrees fractions – for a civil submarine) parametric receiving antennas of location type are placed on a civil submarine, remotely-operated and autonomous unmanned underwater vehicles.

The results of long-term use of the latest surface and subsea vehicles for detecting and direction finding of elastic waves sources in the frequency range from Hz fractions up to kHz tens are presented.

 

Key words: continental shelf; northern and Arctic seas; mine­rals; hydrocarbon deposits; prospecting and exploration of hydrocarbons; acoustics; nonlinear underwater acoustics.

CHOICE AND CALCULATION OF SLUG CATCHERS WITH VENTURI THROAT

AT THE INLET OF OIL AND GAS SEPARATION FACILITIES (p. 9)

 

Leonid Markovich Milshtein

 

E-mail: mleonmark@gmail.com

 

The article presents substantiation of Venturi nozzle use as a slug catcher for one separator and a pipe slug catcher-flow distributor with Venturi nozzle for a group of 2...3 parallel separators. Calculations of Venturi nozzle are given for a single oil and gas separator and slug catcher-flow distributor for two and three separators based on Venturi nozzle. Slug catchers should be installed at the inlet of separation units and at the outlet of supply lines, where there exist all conditions for a liquid slug formation. The advantage of slug catchers with Venturi nozzles and slug catchers-flow distributors as compared with devices of preliminary gas removal is shown as one can observe liquid slowdown in Venturi nozzle and slug catcher-flow distributor that the device of preliminary gas removal lacks. The methodology for calculation of a Venturi nozzle and a slug catcher-flow distributor doesn’t contain accounting of gas factor value while determining the necessity of a slug catcher use.

 

Key words: substantiation; use; slug catcher; Venturi nozzle; separator; calculation; advantage; device; removal; gas.

In recent years, for various reasons, there became obvious a steady growth in the number of marginal wells, operation of which by means of using standard sucker-rod pumps is associated with high operational costs.

LLC "Ekogermet-M" developed design and manufactured test specimens of NSBM19 sucker-rod pumps type specially designed for use at marginal wells. Two pumps were tested in "Prikamneft" Oil and Gas Production Department at wells Nos. 1834 and 4811. Reduction of the pump’s plunger diameter up to 19 mm and the rods’ diameter up to 16 mm brings significant reduction of the maximum load on the polished rod, thus decreasing energy consumption by the pump. The design of the pump with the valves with big flow passages arranged in the stationary housing provides better suction conditions, possibility of operation without gas locks and with less loss of motion as compared with conventional pumps.

The testing results generally confirmed technical characteristics of NSBM19 pumps, put into structural concept, and compliance of the pump’s calculation parameters with parameters obtained during tests by means of direct measurements while pumps’ operation in the wells. Some method of calculation of maximum and minimum load on the polished rod, peak torque and power for the motor selection is developed. Manufacture of NSBM19-3.0-1 pumps is organized at the plant of JSC "Prompribor".

 

Key words: sucker-rod pumps; marginal wells; structure; testing; method of load calculation; polished rod; manufacture of pumps.

The article presents results of work aimed at updating the geometry of cutting structures of rolling-cutter drill bits with asymmetrical jet. The analysis of washing liquid’s directions and magnitudes in conditions of asymmetric scheme of drilling tools washing is performed. The causes and conditions of formation of so-called "stagnant" zones are identified. The influence of the geometry of cutting structures of rolling-cutter drill bits on hydraulic media of a well bottom area is studied. The dependence among the rotational speed of rolling-cutter teeth rows, teeth inclination angle and flow rate of the washing liquid is determined. The perspective diagram of a rolling-cutter drill bits with helical cutting structures and asymmetric water jet is developed. The conducted researches witnessed the fact that equipping of rolling-cutter drill bits with helical cutting structures in combination with asymmetric jetting can significantly improve the efficiency of its work due to better performance of this type of cutting structures in conditions of a near zero and low-velocity flow of washing liquid as well as prevention of occurrence of zones with increased sliming and packing.

The article describes the determination of the optimal form of the gland during its deformation. Applied Ritz variational method allows to determine the optimal shape of the gland during its deformation. Ritz method analytically derive an expression for the strain gland and on the basis of a plot of the parameters of the conical angle of the gland from its ratio of the radii. The optimal value of the taper angle is on the range epiploon 30…45. It should be noted that for writing the boundary conditions into account the condition of incompressibility of rubber sealant. It is found that the efficiency of the packing seal is highly dependent on the choice of the geometrical shape, that is the optimal form and parameters of the seal. It also provides a seal gland. Also found that to achieve the effect of self in the stuffing box must create a level of strain and stress for the guaranteed voltage. It was therefore decided to find a form of the packing to compress it after its power was necessary stages.

 

Key words: boomless deep pump; compaction gland; optimal shape; deformation; Ritz method.

Due to transition of a great number of Azerbaijan oil and gas fields to the latest stage of operation there appear various complications, one of which is some increase of medium corrosion activity. That’s why a multifunctional reagent which is not only a bactericide-inhibitor but also promotes oil displacement was developed to protect underground and surface oilfield equipment from corrosion.

Laboratory studies have shown that the reagent has high inhibitory and bactericidal properties in case of 500 mg/l concentration. Moreover, protective effect of the general corrosion makes 93...96 %, the degree of suppression of sulfate reducing bacteria (SRB) is 98 %. While carrying out experimental researches on linear models of a formation, it was found out that 3 % reagent concentration leads to 17 % increase of displacement factor relative to formation water. The developed reagent also prevents scaling though the scaling efficiency makes 79 % with a reagent concentration of 500 mg/l.

 

Key words: corrosion; bactericide-inhibitor; degree of protection; degree of suppression; scaling; oil displacement.

Domestic research and pilot projects aimed at import substitution and increase of products competitiveness gain some special urgency in conditions of economic, technical and technological sanctions of the US and Western European countries. The purpose of such a strategy is reduction of the country’s economy dependence on import without losing any importance and quality of products. State support in this direction is the driving force and the factor that determines the success of such a policy. If the import substitution program in the Russian Federation is implemented at the appropriate level, then, with account of all aspects of the market economy, it will be able not only to stimulate the development of Russia's oil and gas industry, but also to raise it to a qualitatively new level.

Due to the progressive depletion of the resources streamlining of the process of oil and gas fields development becomes topical. In order to increase the oil recovery factor at the fields, different methods of oil recovery intensification and enhancement are considered. Highly efficient and cost-effective methods of oil production intensification are required to upgrade the oil and gas fields, being in operation at present. One of the most effective methods of oil recovery enhancement is the technology of water-alternating-gas effect (WAG), which allows development of hard-to-recover reserves.

The advantage of the technology lies in the possibility of its application in a wide range of geological-physical conditions and at various stages of reservoirs development. Besides, WAG allows solving the problem of gas utilization. Taking into account the fact that the problem of associated petroleum gas (APG) in Kazakhstan is still relevant, WAG technology introduction can be called the best solution of this issue. The WAG technology is a combination of methods of water-flooding and gas injection, the latter of which can be based on used APG use that is produced from the same field.

 

Key words: oil recovery; oil recovery factor; hard-to-recover reserves; water-alternating-gas technology (WAG); indicators of economic efficiency.

Repair of gas pipelines by using steel couplings is the most economical way to restore their load bearing capacity. However, the effectiveness of repairing a pipeline by means of couplings depends on several factors such as the size of the gap between the coupling and the pipe and coupling’s thickness. In practice, when repairing pipelines’ damaged portions, there used couplings with pipe shell thickness equal to and often greater than the wall thickness of the pipe. It doesn’t always produce a positive effect on the efficiency of repair of a pipe’s damaged area, since the excessive wall thickness of a coupling shell makes it more rigid, that can initiate development of local fracture zones. In the course of this work some calculation dependence was obtained for determining the optimal wall thickness of the coupling with account of spacing gaps between the coupling and the pipe during installation as well as the results of couplings ground testing conducted under operational and failure loads.

 

Key words: gas pipeline; coupling; repair; field testing; contact pressure; power efficiency coefficient.
