Problems solved by technology

[0002] When coiled tubing and traditional steel tubing are raised in oil well production, a large amount of oil stains are attached to their outer surfaces. During the well lifting operation, the oil stains on the outer wall of the tubing cannot be cleaned, so the ground and the surrounding wellhead will be damaged during the operation. The vegetation causes pollution, and the working environment of the construction personnel is damaged. During the operation, the construction personnel are always in the oil sludge, which is not conducive to personal safety. In addition, the oil pollution will also pollute the operation equipment and transmission equipment, which will directly affect the use of equipment, and increase The cleaning and maintenance costs of the equipment are reduced; more importantly, the spilled crude oil seeps into the ground and cannot be recovered, and the waste of crude oil caused by long-term operation is considerable

Abstract

The invention discloses an oil tube surface cleaning, blowout-preventing and flow-guiding device. The device comprises an upper gland, a cleaning chamber, flow-guiding grooves, a fixed supporting foot, a rubber ring supporting rack and an oil tube through hole, the rubber ring supporting rack is arranged at the upper end of the fixed supporting foot, the oil tube through hole is arranged in the center of the rubber ring supporting rack, a movable end cap is movably arranged above the oil tube through hole, the flow-guiding grooves are arranged in two sides of the oil tube through hole, the flow-guiding grooves are provided with flow-guiding openings, the cleaning chamber is arranged between the upper gland and a cleaning solution guiding tube, and a liquid inlet is arranged above the cleaning chamber. The device has a simple structure, makes an oil tube very clean through primary flowing cleaning of the surface of the oil tube by using the liquid inlet and secondary cleaning of the surface of the oil tube by using the rotating deformation of a wax cleaning rubber ring, avoids oil stain diffusion through collecting oil stains by the flow-guiding grooves and the flow-guiding openings, avoids oil stain spray through a pressure relief and blowout-prevention hole, and realizes fast loading and unloading through flange connection.

Description

technical field [0001] The invention relates to the technical field of petroleum engineering, in particular to an oil pipe surface cleaning blowout prevention flow guiding device. Background technique [0002] When coiled tubing and traditional steel tubing are brought out in oil well production, a large amount of oil stains are attached to their outer surfaces. During the well lifting operation, the oil stains on the outer wall of the tubing cannot be cleaned, so the ground and the surrounding wellhead will be damaged during the operation. The vegetation causes pollution, and the working environment of the construction personnel is damaged. During the operation, the construction personnel are always in the oil sludge, which is not conducive to personal safety. In addition, the oil pollution will also pollute the operation equipment and transmission equipment, which will directly affect the use of equipment, and increase The cleaning and maintenance costs of the equipment ar...
