Environment-friendly operation device preventing oil and water from falling on ground

Abstract

The invention relates to the technical field of oil field workover operation accessory devices, in particular to an environment-friendly operation device preventing oil and water from falling on the ground. The device can prevent cleaning waste liquid from causing pollution and improve the environmental friendliness. An oil pumping rod, the inner wall of an oil pipe and the outer wall of the oil pipe are cleaned one by one, and the working efficiency is improved. The device comprises an oil pumping rod cleaning device, an oil pipe inner wall cleaning device and an oil pipe outer wall cleaningdevice. The oil pumping rod cleaning device comprises a three-way pipe nipple, a first outer cylinder, a first oil suction pipe, a first water injection pipe, a first inner cylinder, a first sealing ring, a second sealing ring, a first cleaning hole, a first blowout-prevention rubber plate and a first upper cover. The oil pipe inner wall cleaning device comprises a second outer cylinder, a secondinner cylinder, a cleaning cylinder, a second water injection pipe, a second upper cover, an umbrella-shaped structure, an oil suction hole, a third sealing ring and a second cleaning hole. The oil pipe outer wall cleaning device comprises a shell, a third upper cover, a second blowout-prevention rubber plate, a third water injection pipe, a second oil suction pipe, a third inner cylinder, a fourth sealing ring, a fifth sealing ring and a third cleaning hole.

Description

technical field [0001] The invention relates to the technical field of attachments for oil field workover operations, in particular to an environmental protection operation device that prevents oil and water from falling to the ground. Background technique [0002] As we all know, in minor oil and water well repair construction operations, the proposed sucker rods and oil pipes need to be cleaned on the ground according to the construction requirements, and the cleaned crude oil and sewage will pollute the ground environment. The operation mode of the traditional wax removal process is: Lift the sucker rods and oil pipes one by one to the ground, and then use high-temperature steam to clean the outer walls of the oil pipes and sucker rods, and clean the inner walls of the oil pipes by opening the diameter gauge with steam; It was found that crude oil and wax are easy to spill, and it is necessary to lay three-proof cloth on the ground, which is easy to cause environmental po...
