Elastic pipeline inner wall scraping and washing device

Abstract

The invention discloses an elastic pipeline inner wall scraping and washing device. The elastic pipeline inner wall scraping and washing device mainly solves the problems that when an existing paraffin pushing ball and a high-pressure water flow cleaning device clean a pipeline, the pipeline is prone to being blocked or not being thoroughly cleaned are mainly solved. The elastic pipeline inner wall scraping and washing device is characterized in that a paraffin scraping spring base (2) is arranged at the rear end of a guide head (1), a conical paraffin scraping spring (3) is fixed to the paraffin scraping spring base (2), a guide spring front end connector (9) is arranged at the rear end of the paraffin scraping spring base (2), the front end of the guide spring front end connector (9) isconnected into the guide head (1) through threads, the rear end of the guide spring front end connector (9) is connected with a guide spring (5), the rear end of the guide spring (5) is fixed to a guide spring rear end connector (6), a plurality of spraying openings (7) are formed in the side wall of the guide spring rear end connector (6), and the rear end of the guide spring rear end connector (6) is connected with a water blocking leather cup (8) through a plug (11). The elastic pipeline inner wall scraping and washing device cannot cause pipeline blockage and is thorough in washing.

Description

technical field [0001] The invention relates to the field of oil fields, in particular to a scraping and cleaning device for the inner wall of an elastic pipeline. Background technique [0002] During oilfield production, wax and oxides will adhere to the inner wall of the pipeline, which will reduce the inner diameter of the pipeline and affect crude oil production. At present, it is often used to drop wax balls or use high-pressure water flushing to remove wax from the pipeline, but the wax balls are often broken and stuck due to scratching at the elbow of the pipeline, or the pipeline is blocked due to excessive accumulation of impurities. and other accidents, while the simple high-pressure water flushing effect is small, and the cleaning is not thorough. Contents of the invention [0003] In order to overcome the problem that the existing wax ball and high-pressure water cleaning device are prone to pipeline blockage or thorough cleaning when cleaning the pipeline, th...
