Environment-friendly device for swabbing operation site

Abstract

The invention discloses an environment-friendly device for a swabbing operation site. The environment-friendly device for the swabbing operation site comprises a top sheave protective cover; the top sheave protective cover covers outside a top sheave; a steel wire rope inlet and a steel wire rope outlet are formed in the bottom of the top sheave protective cover; a steel wire rope protective pipeis arranged on a swabbing steel wire rope in a sleeving manner; the upper end of the steel wire rope protective pipe is connected with the steel wire rope inlet; the lower end of the steel wire rope protective pipe is connected with the upper end of a liquid collecting barrel of a blowout preventing box in a sealing manner; the liquid collecting barrel of the blowout preventing box is arranged onthe outer side of a closed swabbing blowout preventing box in a sleeving manner; the bottom of the liquid collecting barrel of the blowout preventing box communicates with a wellhead liquid collectingplatform; a plurality of swabbing steel wire rope runway liquid collecting grooves are closely arranged below a horizontal steel wire rope in sequence; and a tractor hoist chassis is arranged below atractor hoist roller. According to the environment-friendly device for a swabbing operation site, the leakage of crude oil sewage at the top sheave, the swabbing steel wire rope, a blowout preventingbox part, the horizontal steel wire rope and a tractor hoist, and the scattering of oil on the ground are effectively avoided through the top sheave protective cover, the steel wire rope protective pipe, the leakage liquid collecting barrel of the blowout preventing box, the swabbing steel wire rope runway liquid collecting grooves and the tractor hoist chassis; centralized collection of the crude oil sewage is realized; and the requirements on clean production and green formation testing are met.

Description

technical field [0001] The invention belongs to the technical field of oil and gas field development, in particular to an environmental protection device for swabbing operation sites. Background technique [0002] Swabbing operation, as a common process for liquid drainage and production, has been skillfully applied to various oil testing sites in oil fields. With the development of technology, different forms of drainage methods have gradually begun to be tested on site, but the relatively primitive method of swabbing still has its unique advantages on site. Due to the requirements of well control and environmental protection, after a long period of exploration, the airtight swabbing blowout preventer came into being. It has achieved a large degree of effect in solving the environmental pollution problems such as crude oil landing on site, but the crude oil landing is still cannot be completely resolved. [0003] The oil testing and swabbing operation is usually the proce...
