Descaling device for oilfield water pouring pipe and operation method

Abstract

The invention provides a descaling device for an oilfield water pouring pipe and an operation method. The device comprises a circular sleeve, wherein a group of inserting holes is formed around the circumference of the circular sleeve; transverse thread sleeves which are connected to transverse thread rods are welded to the inserting holes; the transverse thread rods are connected to transverse supporting rods; fixing sleeves are inserted to the outer sides of the transverse supporting rods; fixing holes are formed in the transverse supporting rods; concentric fixing holes are formed in the fixing sleeves and are overlapped with the fixing holes and are fixed through bolts; arc-shaped scrapping plates are welded to the fixing sleeves; the top parts and the bottom parts of the arc-shaped scrapping plates are provided with cutting edges; a group of supporting plates is connected around the circumference of the circular sleeve; the supporting plates are connected to screw sleeves which are connected to screws; and the screws are connected to couplings which are connected to motors. The device is applicable to descaling the oilfield water pouring pipe.

Description

[0001] Technical field: [0002] The invention relates to a descaling device for oilfield water injection pipes. [0003] Background technique: [0004] Scale will appear on the water injection pipe in the oil field after a long time of use. It is very inconvenient to clean the scale. Because the length of the water injection pipe in the oil field cannot allow the arm to reach in to clean it, it is inconvenient to clean it, and it is impossible to use chemicals to clean it. [0005] Invention content: [0006] The object of the present invention is to provide an oil field water injection pipe descaling device that can clean out the scale smoothly and has good use effect. [0007] Above-mentioned purpose realizes by following technical scheme: [0008] An oil field water injection pipe descaling device, which consists of: a circular sleeve, the circular sleeve has a group of sockets around the circumference, the sockets are welded with a horizontal threaded sleeve, and the hor...
