Abstract

The invention discloses a centrifugal type steel brush used for the inside of a petroleum casing pipe and belongs to the technical field of corrosion protection of petroleum casing pipes. The centrifugal type steel brush used for the inside of the petroleum casing pipe comprises a steel brush head, wherein the left end of the steel brush head is fixedly connected with a slide rail rod; the slide rail rod is sleeved with a movable brush rod; the upper end of the steel brush head is fixedly connected with a small motor; a motor rotating shaft is arranged in the middle of the small motor; the motor rotating shaft is rotationally connected with the small motor; one end of the motor rotating shaft away from the small motor is sleeved with a turntable; the upper end of a reciprocating track plate is provided with a reciprocating track; a steel brush push rod is arranged in the reciprocating track; the right end of the steel brush push rod is fixedly connected with an intermittent rotating shaft; the right end of the intermittent rotating shaft is fixedly connected with a unidirectional rotation rod; the lower end of the steel brush head is fixedly connected with a return half ring; the left end of the return half ring is fixedly connected with a return spring; and the left end of the return spring is fixedly connected with the movable brush rod. The cleaning effect of the steel brushused for the inside of the petroleum casing pipe is improved through the structure.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of petroleum casing, and more specifically relates to a steel brush for centrifugal type petroleum casing. Background technique [0002] Oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well needs to use several layers of casing according to different drilling depths and geological conditions. Cement cementing is used after the pipe is lowered into the well. It is different from oil pipe and drill pipe and cannot be reused. It is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. Divided into conduit, surface casing, technical casing and oil layer casing. The advantages of the existing centrifugal steel brush for oil casing are: simple equipment, easy disassembly and assembly, easy operation, no...
