Mechanical unblocking petroleum pumping pipe

Abstract

The invention provides a mechanical unblocking petroleum pumping pipe. The mechanical unblocking petroleum pumping pipe comprises a petroleum pumping pipe body, a screening pipe arranged in a pipelineof the petroleum pumping pipe body, an electric valve, a remote controller connected with the electric valve through electric signals, a one-way rubber valve and a pressure pipe. With the flowing direction of petroleum when the petroleum pumping pipe body pumps petroleum as a front direction, the electric valve is disposed in the pipeline of the petroleum pumping pipe body in front of the screenpipe; the one-way rubber valve is disposed in the pipeline of the petroleum pumping pipe body behind the screen pipe and is of an annular structure, an annular surface of the one-way rubber valve is acurved surface and is a surface bending and extending from an annular outer ring to an inner ring and the screen tube, and the inner ring is an annular space; one end of the pressure pipe is communicated with an air compression pump, and the other end of the pressure pipe is communicated with the interior of a pipe cavity of the screen pipe. The mechanical unblocking petroleum pumping pipe achieves mechanical unblocking by using air pressure recoil, the screen pipe is unblocked, and therefore the problem of clogging of the petroleum pumping pipeline can be solved.

Description

technical field [0001] The invention relates to the technical field of plugging removal of oil well screen pipes, in particular to a mechanical plugging removal oil suction pipe. Background technique [0002] Oil is mainly stored in pores in rock formations, forming reservoirs. During the oil extraction process, the oil production pipeline needs to be deep into the oil reservoir to exploit the oil stored in the oil reservoir. [0003] In the prior art, along with the exploitation of oil in the reservoir, there are often some solid particles or colloids, such as sand, rock soil, asphalt, oil gel, etc., during the oil pumping process, which will block the oil pumping pipeline, especially It is the screen part in the oil extraction pipeline. Will seriously affect the oil output of oil production well at last, so need a kind of device that can solve the clogging problem of oil pumping line urgently. Contents of the invention [0004] In view of the problems in the prior art...
