Abstract

The invention relates to the technical field of oil field equipment, in particular to a descaling wax-removing device for the oil field equipment. The descaling wax-removing device comprises a shell body, a knife blade assembly arranged in the shell body, and a coupling located on the bottom of the shell body, wherein a rubber core assembly is arranged above the knife blade assembly, and the knife blade assembly comprises a hinge, a hinge shaft, a floating body, a knife blade, a scraper knife supporting base, a plate spring and a magnetic steel assembly controlling operation of the knife blade. By the adoption of the structure, the operation of the knife blade is controlled through the magnetic steel assembly at first, then a tension spring assembly controls operation of the rubber core assembly, accumulated wax, accumulated oil and accumulated scale on the outer surface of a sucker rod, the outer surface of an oil pipe and the outer surface of a drill rod are timely cleared away successively through the knife blade assembly and the rubber core assembly, cleaning effects are good, time and labor are saved, operation is safe and reliable, environment pollution is prevented, and environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of oil field equipment, in particular to a descaling and wax removal device for oil field equipment. Background technique [0002] At present, during the downhole operation, when the sucker rod, tubing and drill pipe are pulled out, a large amount of wax, oil and various scales will be attached to the outer surface, which needs to be removed in time. The existing technology mainly adopts steam heating method to remove the wax deposit or oil deposit. , waste manpower and material resources, and will cause greater pollution to the environment. Contents of the invention [0003] The object of the present invention is to provide a descaling and waxing device for oil field equipment which is safe and reliable in operation, can remove scale and wax deposits in time, saves time and labor, and is beneficial to environmental protection. [0004] In order to solve the problems existing in the background technology...
