INFLUENCE OF GAS CONTENT IN OIL ON EFFICIENCY OF THE DOWNHOLE SUCKER ROD PUMP
http://www.ogbus.ru/authors/Rozhkin/Rozhkin_1.pdf (in Russian)
The article deals with the task of determining the effectiveness of the downhole sucker rod pump with deleterious effects of dissolved gas in oil. The results obtained in the paper show that the nonequilibrium factor significantly affects the efficiency of the borehole pumps. However, it should be borne in mind that these results were obtained in bench conditions, ie in circumstances where possible to provide only the influence of gas oil at the rate filing. Naturally, in the real world, such analysis can not hold. In this case you need statistical data processing operation of wells.
Keywords: gas content, modelling, downhole sucker rod pump, the rate filing

REINFORCEMENT OF CARRYING ABILITY OF ICE FERRIES AND MARSHY ROADS
http://www.ogbus.ru/authors/Gerasimov/Gerasimov_1.pdf (in Russian)
Development of stocks of hydrocarbon raw material and investigation of their site today moves ahead more and more on northern territories of Russia, where there is no developed high system. The technics of oil-and-gas branch and transport on its delivery becomes more powerful, increasing in weight. At the time global changes in a climate remove in later terms of becoming of safe carrying ability of ice ferries and marshy roads. All this dictates development of the ways reinforcement of carrying ability of ice ferries and marshland.

DETERMINING OF COUPLED WATER IN SAMPLES ROCKS AT MICROWAVE FREQUENCIES
http://www.ogbus.ru/authors/Tabarin/Tabarin_1.pdf (in Russian)
This paper describes the first results of our laboratory investigation of the formation constitutient (rock matrix and borehoule fluids) and the composite formation. The electromagnetic propagation tool has demonstrated that the dielectric permittivity of rocks at microwave frequencies. This investigation are helpful in determining the properties of the rocks and the fluids contain, especially coupled water. Electrical parameters of rocks with fluids are found generally complex. A technique has been developed for measuring the complex dielectric ptrmittivity over a microwave frequency bands (8.15 to 12 GHz). Measurements on bulk water of various salinities demonstrate the salinity dependence of the dielectric constant () of water at high salinities. The measured a dielectric loss () shows little dispersion and is in good agreement with measured low-frequency values by other investigators. All measurements are made with samples of different porosity (3 to 24%) and saturated porous water (88.9 to 32.6%). Error of measurements 10% be achieved.
Keywords: rock, coupled water, complex dielectric permittivity, microwave frequencies, quasi-optical measurement

ABOUT REALIZATION OF NEW COMPOSITE SYSTEM TECHNOLOGY FOR SALT SCALE CONTROL
http://www.ogbus.ru/authors/Rustamov/Rustamov_1.pdf (in Russian)
In the presence article the questions of salt scale formation in operational objects during an crude production are described. By the example of given problem analysis on a number of oil field in Russia, Azerbaijan and Kazakhstan was shown, that the salt scale problem especially strongly appear on a protractedly developed oil Fields. At that it is emphasized, that the wells operated by submersible electric centrifugal pump unit are range to a high risk group.
It is marked, that microbiological processes additionally complicate the problem due to a complex structure of scale deposit formation. Principal causes of salting-up process in bottom-hole area and primary reason of operational unsuccessfulness of some geologic and technical activity for rehabilitation of reservoir quality on the critical area of formation are described.
With the purpose of geologic and technical activity effectivization the technology of bottom hole treatment based on using ammonium chloride in a combination with surface active agent is offered.
Keywords: salt scale, watering, bottom-hole zone, submersible electrical centrifugal pumping, deposition with complex composition, inhibitors, ammonium chloride

http://www.ogbus.ru/authors/Jafarov/Jafarov_2.pdf (in Russian)
The problem of maintenance of high level of reliability and efficiency of functioning of gas pipelines is a complex problem. One of principal causes of deterioration of working capacity of a gas pipeline is its corking (partial or full). For working out of operative methods of detection of corking and acceptance of timely engineering decisions providing a normal mode of functioning of a gas pipeline, is represented the question of diagnostics of an internal surface of a gas pipeline actual.
For research of influence of a zone of corking on the stationary characteristic of a gas stream has been collected experimental installation. Have been considered various volumes of corking of a gas pipeline. On the basis of researches for practical calculations is offered the technique of definition of a place of corking of a gas pipeline.
Keywords: gas supplying system, the rising of reliability, analyses the condition, zones formation of hydrate accumulation
