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 recycling device beneficial to a low yield well. The recycling device comprises a hydraulic power system, an oil extracting device and an API underground inserting pump, wherein the hydraulic power system is used for driving a steel wire rope to drive a weighing rod or a cable connector connected with a polish rod to further drive the API underground inserting pump to doup-down reciprocating motion; the oil extracting device comprises the polish rod, a high-pressure union, an oil tube short circuit and a pump tee joint; the lower end of the high-pressure union is inbutt joint with the oil tube short circuit; the lower end of the oil tube short circuit is in butt joint with the upper end of the pump tee joint; the lower end of the polish rod is connected with theweighing rod; the upper end of the polish rod is connected with a steel wire rope; the API underground inserting pump comprises a sleeve and a valve rod; the sleeve is connected with the oil tube; and the valve rod is connected with the weighing rod or the cable connector to penetrate into the sleeve. The recycling device has the advantages of long stroke, low maintenance and energy consumption,automation control and capacity of reducing oil tube wear and drill pipe falling.

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...
