Изобретение может быть использовано при добыче в зких структурообразуюш,их нефтей и нефт ных эмульсий.The invention can be used in the extraction of viscous structured structures, their oils and oil emulsions.

Известна глубиннонасосна установка, содержаща глубинный насос и колонны насосно-компрессорных труб и штанг 1. Дл облегчени работы установки в скважинах .с высоков зкой нефтью, предусмотрена изол ци колонны насосных труб от высоков зкой нефти. Однако процесс эксплуатации скважины сложен.A well pumping installation is known, comprising a submersible pump and tubing columns and rods 1. To facilitate the operation of the installation in wells with high-viscosity oil, insulation of the pumping tubing from high-viscosity oil is provided. However, the process of operating the well is complicated.

Наиболее близкой к изобретению вл етс глубиннонасосна установка, содержаш ,а насос и колонны насосно-компрессорных труб и штанг 2.Closest to the invention is a pumping installation, containing, and the pump and tubing and boom columns 2.

Цель изобретени - повышение надежности работы за счет снижени амплитуды нагрузок на колонну штанг в момент запуска глубиннонасосной установки.The purpose of the invention is to increase the reliability of operation by reducing the amplitude of the loads on the rod string at the moment of launching the deep-pump installation.

Указанна цель достигаетс тем, что предлагаема установка снабжена компенсаторами , выполненными в виде патрубков, коаксиально установленных относительно колонны насосно-компрессорных труб, и образуюШ .ИМИ с ней камеры, сообщающиес с внутренней полостью насосно-компрессорных труб.This goal is achieved by the fact that the proposed installation is equipped with compensators, made in the form of nozzles, coaxially installed relative to the tubing string, and forming a chamber with it communicating with the internal cavity of the tubing.

На чертеже изображена глубиннонасосна установка с увеличенным разрезом компенсатора .The drawing shows a depth installation with an enlarged section of the compensator.

Установка содержит насос 1, колонну насосно-компрессорных труб 2, колонну штанг 3, компенсаторы 4, выполненные в виде патрубков, образующих с колонной насосно-компрессорных труб 2 камеры 5, которые через окна 6 гидравлически св заны с внутренней полостью 7 колонны насосно-компрессорных труб 2.The installation includes a pump 1, a column of tubing 2, a column of rods 3, compensators 4, made in the form of nozzles forming chambers 5 with the tubing 2 column, which are hydraulically connected with the internal cavity 7 of the tubing column through the windows 6 pipes 2.

В процессе спуска труб в скважину верхн часть компенсаторов 4 остаетс заполненной воздухом. По мере эксплуатации часть этого воздуха может замен тьс газом , сепарируемым из нефти.In the process of lowering the pipes into the well, the upper part of the compensators 4 remains filled with air. As exploitation proceeds, a part of this air can be replaced by gas separated from oil.

Claims

When starting the well at the initial moment of the stroke of the rod string, upward movement from the plunger of pump 1 is transmitted not to the entire liquid column, but only to its lower part, i.e., the section from the plunger of pump 1 to the installation location of the first compensator 4. This is due to the fact that frozen oil is extremely difficult to move along the entire length of tubing, which is the cause of heavy loads and breaks in the rods. Compressing the gas in the first compressor 4 and partially filling it with the produced fluid under the influence of the resulting hydrodynamic pressure makes it possible to destroy the structure of oil in this area and put it in motion. After the gas is maximally (for a given pressure) compressed in the first compensator, the process of destroying the structure of oil in the second section begins, etc. Gradual destruction of the structure of oil formed during the equipment shutdown makes it possible to significantly reduce the starting load on the pump unit. The presence of such compensators has a positive effect on the operation of the installation and in normal conditions of well operation. At the initial moments of the stroke of the rocker of the pumping unit, the inertial liquid loads are sharply reduced due to the damping effect of the pneumatic compensators. This leads to a reduction in the number of cliffs in high-accident wells, whose products have high viscosity. Claims of the invention The deep-well pumping installation containing the pump and columns of pump-compressor pipes and rods, is characterized in that, in order to increase the reliability of the operation by reducing the amplitude of the loads on the column of the rods at the time of launching the deep-well pumping installation, it is equipped with compensators in the form of connections coaxially mounted relative to the column tubing, and forming a chamber with it, communicating with the internal cavity of the tubing.
