Problems solved by technology

Drainage device is mainly to solve the problem of normal oil pumping by oil well pumps. Now most of the oil fields have entered the middle and late stages, and most of them are oil wells with water, gas, wax and sand content, which will cause certain difficulties for oil pumping. , the oil pump will be stuck or the screen will be blocked, which will directly affect the production of the oil well

Embodiment Construction

[0012] The device is mainly composed of two parts: the oil well pump assembly and the multi-phase separation self-cleaning drainage device. When going down the well, 10-20 tailpipes equipped with plugs are lowered into the well first, and then connected to the multi-phase separation self-cleaning drainage device sequentially. The extraction device is then connected in series with several oil pipes, and then the oil well pump assembly and the oil pipe are connected in series until reaching the total length of the oil pipe string. The multi-phase separation self-cleaning drainage device is designed and manufactured using the principle of fluid inertia and centrifugal force. It is connected with the oil pump assembly and then lowered into the oil well. The medium enters the device through the through hole of the outer tube of the device to realize gas, sand, The liquid is automatically separated, and the separated gas is discharged into the oil casing annulus through the upper fou...

Abstract

A multi-phase separation self-cleaning drainage device is formed by a shell (5), a stainless steel wire winding type screen pipe (4), an upper connector (3) and a tail pipe (8). The multi-phase separation self-cleaning drainage device is characterized in that the stainless steel wire winding type screen pipe (4) is connected in an inner hole of the upper connector (3) through threads, an outer pipe (5) is sleeved on the outer circle of the stainless steel wire winding type screen pipe (4), a through hole is milled in the upper portion of the outer pipe (5) and tangent to the inner hole, and the included angle between the through hole and the generatrix is 110-160 degrees. A through hole in the lower portion of the outer pipe is milled to be tangent to the inner hole, and the included angle between the through hole and the generatrix is 20-70 degrees. The multi-phase separation self-cleaning drainage device further has the functions of degritting and degasification besides the function of pumping, so that the drainage efficiency is improved, the service life of an oil-well pump is prolonged, and economic benefits of oil pumping are increased.

Description

technical field [0001] The invention relates to a drainage device used in the field of oil recovery in an oil field, in particular to a self-cleaning drainage device. Background technique [0002] In the field of oil recovery, the oil recovery device is an important equipment for oil recovery. Drainage device is mainly to solve the problem of normal oil pumping by oil well pumps. Now most of the oil fields have entered the middle and late stages, and most of them are oil wells with water, gas, wax and sand content, which will cause certain difficulties for oil pumping. , the oil pump will get stuck or the screen will be blocked, which will directly affect the production of the oil well. Contents of the invention [0003] In order to overcome the above-mentioned defects of the existing extraction devices, the present invention provides a multi-phase separation self-cleaning extraction device. Characteristics of oil recovery costs. [0004] The technical solution adopted ...
