Abstract

The invention relates to an oil pipe inner wall cleaning device and method. The oil pipe inner wall cleaning device comprises an air compressor, an air supply hose, a switch valve, a quick inserting connector and a recovery device; an air compressor is connected with one end of the quick inserting connector through the air supply hose; the other end of the quick inserting connector is connected with an oil pipe connector; the recovery device is arranged at the end of a to-be-cleaned oil pipe; the air supply hose is provided with the switch valve; the quick inserting connector comprises a connector body, a locking mechanism and a flow guide structure; the flow guide structure is fixed into the connector body; the locking mechanism is fixed to the outer wall of the connector body; the frontsection of the connector body is provided with a fixing groove; and a sealing gasket is arranged in the fixing groove and located between the oil pipe connector and the connector body. The oil pipe inner wall cleaning device has the advantages that the oil pipe inner wall cleaning problem is solved, the construction period is short, the efficiency is high, the construction cost is reduced, and theeffect that cleaning work is completed within one minute is ensured.

Description

technical field [0001] The invention relates to a device and a method for cleaning the inner wall of an oil pipe. Background technique [0002] In the process of oil field workover operations, after the tubing in the oil well is taken out of the well, the inner wall needs to be cleaned to remove wax and oil. Since the tubing has a long outer dimension (about 9.6m) and a small inner hole, it is a slender pipeline. The inner wall of the tubing should be cleaned difficulty. At present, there are two cleaning methods. One is to use a special cleaning machine to clean the oil pipe after it is transported back to the site. This method requires the oil pipe to be transported back to the factory area, which is inconvenient for transportation, long construction period and low work efficiency. The other is to use high-pressure hot water guns for spray cleaning on site. This method requires on-site configuration of hot water boilers and inner tube high-pressure spray guns, and the equ...
