Sucker rod wax scraper based on high-temperature wax removal

Abstract

The invention discloses a sucker rod wax scraper based on high-temperature wax removal. The sucker rod wax scraper comprises an oil pipe wall, an outer wall cleaning cylinder and an inner wall cleaning cylinder. The inner wall cleaning cylinder is made of an annular magnet. The edges on the two sides of the inner wall cleaning cylinder are each provided with a layer of adhesive leather sheath. A plurality of inner wall high-temperature water spray guns are evenly arranged on the outer ring of the adhesive leather sheath on one side. The axes of the inner wall high-temperature water spray guns deviate from the diameter of the inner wall cleaning cylinder where the inner wall high-temperature water spray guns are located. The deviation angles between all the inner wall high-temperature water spray guns and the diameters of the inner wall high-temperature water spray guns are identical. Inner wall high-temperature blades are evenly arranged on the outer ring of the adhesive leather sheath on the other side. The perpendicular lines of the inner wall high-temperature blades deviate from the diameter of the inner wall cleaning cylinder where the inner wall high-temperature blades are located. The deviation angles between all the inner wall high-temperature blades and the diameters of the inner wall high-temperature blades are identical. According to the sucker rod wax scraper based on high-temperature wax removal, the effect that the inner wall and the outer wall are cleaned at the same time is achieved, meanwhile, the flexibility of oil pipe cleaning equipment is guaranteed, and a better paraffin wax removal effect is achieved.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a sucker rod wax scraper based on high temperature wax removal. Background technique [0002] In the process of oil extraction, crude oil is pumped up through the oil pipe, because the sediment, paraffin and other impurities in the crude oil (especially heavy oil) will block the oil pipe, as well as corrosion, electric pump failure and other reasons, so each oil well needs Perform periodic inspections. At this time, the oil pipe needs to be extracted for repair. The operation process is to use the hoisting system to lift the tubing strings in the oil well out of the wellhead, unload them one by one and place them on the tubing storage rack, then clean, measure, reassemble, and then lower them into the well one by one. In the process of oil production, the cost of oil pipe cleaning has always been an important part of the production cost of oil production plants. The cleaning...
