Problems solved by technology

[0002] The transmission oil production system mainly includes kowtow machine (beam pumping unit) and electric submersible pump. The existing kowtow machine has the problems of short stroke, high maintenance cost, high energy consumption, oil pipe wear and drill pipe easy to fall off. An electric submersible pump is a downhole pump with a motor, which is not suitable for low-production wells due to its high purchase cost, high repair cost, and no water cut control.

Abstract

The invention discloses a recovery device for low-production wells, which includes: a hydraulic power system, which is used to drive a steel wire rope to drive a weighted rod connected to a polished rod or a cable connector to drive an API downhole insertion pump to reciprocate up and down; an oil production device, which includes a polished rod, a high-pressure The union, the oil pipe are short-connected and the pump tee; the lower end of the high-pressure union is short-connected with the oil pipe, and the lower end of the oil pipe is short-connected with the upper end of the pump tee; the lower end of the polished rod is connected with the weight rod, and the polished rod The upper end of the pipe is connected with the wire rope; the API downhole insertion pump includes a sleeve and a valve stem, the sleeve is connected to the oil pipe, and the valve stem is connected with a weighted rod or a cable connector and penetrates into the sleeve. The invention has the advantages of long stroke, low maintenance, low energy consumption, automatic control and at the same time reduces oil pipe wear and drill pipe shedding.

Description

technical field [0001] The invention relates to the technical field of oil and gas drilling equipment. More specifically, the present invention relates to an apparatus for facilitating recovery of low production wells. Background technique [0002] The transmission oil production system mainly includes kowtow machine (beam pumping unit) and electric submersible pump. The existing kowtow machine has the problems of short stroke, high maintenance cost, high energy consumption, oil pipe wear and drill pipe easy to fall off. An electric submersible pump is a downhole pump with a motor, which is not suitable for low-production wells due to high purchase costs, high repair costs, and no water cut control. Contents of the invention [0003] The purpose of this invention is to provide a recovery device for low-production wells, which is an easy-to-use and easy-to-optimize artificial lift solution, with the advantages of long stroke, low maintenance, low energy consumption, and au...
