Problems solved by technology

The inner diameter of the pipe diameter is reduced, causing testing, salvage and other tools to fail, which seriously affects the normal work.
Oilfield workers usually use a certain diameter well gauge to solve this problem, but the well gauge relies on gravity impact to work, and the impact force of the well gauge is limited by weight, so it often cannot pass
And the hard scale layer, the diameter gauge can not remove it at all

Abstract

The invention relates to hydraulic oil pipe scale borer, including a fishing head (1), a main part (2), a core bar (3), a joint (4), a rubber tube core (5), a rubber tube assembly (6), a bonding body (7), a descaling part (8) and a guide head (9), the outside wall of the descaling part (8) is provided with a number of spiral cutting edges (81), the core bar (3) located on the bar body inside the main part (2) is provided with a number of impellers (31),the side wall of the main part (2) above each impeller (31) is respectively provided with an inlet hole (21), the side wall of the main part (2) below each impeller (31) is respectively provided with an outlet hole (22), the inside wall of the main part (2) below each outlet hole (22) is respectively rotated with the core bar (3) and is closely sealed and coordinated. The scale borer does not have to rely on gravity impact in order to work, and descales with better effect. The spiral descaling mechanism uses hydraulic force to push the spiral scale borer to descale the pipe, and alleviates the difficult job of cleaning up oil pipe scale.

Description

technical field [0001] The invention relates to petroleum tools, in particular to an oil pipe descaling device for descaling operations of oil and water wells in oil fields. Background technique [0002] After long-term operation of oil and water wells in the oil field, a large amount of oil, scale and other dirt are attached to the inner surface of the oil pipe. The internal diameter of the pipe diameter is reduced, causing testing, salvage and other tools to fail, seriously affecting the normal work. Oilfield workers usually use well gauges of a certain diameter to drill wells to solve this problem, but the well gauges rely on gravity impact to work, and the impact force of the well gauges is limited by weight, so they often cannot pass through. And the hard scaling layer cannot be removed by the diameter gauge at all. Contents of the invention [0003] The object of the present invention is to provide a hydraulic oil pipe descaling device which does not rely on gravit...
