Embodiment Construction

[0012] It includes a large-diameter oil pump 3, a small-diameter annular valve oil pump 50, a small oil pipe 1, a large oil pipe 2, an oil pipe holder 6, a casing 9, a wellhead 10, a sucker rod 4, and a pumping unit 15. Casing pipe 9, wellhead 10, sucker rod 4, and pumping unit 15 belong to the necessary equipment of oil well, and do not belong to the content of the present invention. Large oil pipe 2 is arranged in casing pipe 9. Through the oil pipe fixer 6, the top of the large oil pipe 2 is fixed on the middle part of the small oil pipe 1. The large-diameter oil well pump 3 is inserted into the casing 9 and fixed on the bottom of the large oil pipe 2, and the small-diameter ring valve oil well pump 50 is fixed on the bottom of the small oil pipe 1. The small oil pipe 1 is inserted into the large oil pipe 2 from the oil pipe holder 6 on the top of the large oil pipe 2, and extends downward to connect with the upper part of the small diameter ring valve oil well pump 50.

Abstract

The invention relates to a high deviated horizontal well oil well pump. The high deviated horizontal well oil well pump comprises a major diameter oil well pump(3), a minor diameter ring valve oil well pump(50), a small oil pipe(1), a big oil pipe(2), an oil pipe fixer(6), a sleeve(9), a well head(10), a sucker rod(4), a pumping unit(15), wherein, the sleeve(9), the well head(10), the sucker rod(4) and the pumping unit(15) are characterized in that: the big oil pipe(2) is arranged inside the sleeve(9), the top of the big oil pipe(2) is fixed on the middle part of the small oil pipe(1) by the oil pipe fixer(6), the major diameter oil well pump(3) is arranged inside the sleeve(9) and fixed on the bottom of the big oil pipe(2), the minor diameter ring valve oil well pump(50) is fixed on the bottom of the small oil pipe(1), the small oil pipe(1) is inserted in the big oil pipe(2) from the oil pipe fixer(6) on the top of the big oil pipe(2) and extends downward and is connected with the upper part of the minor diameter ring valve oil well pump(50); in the minor diameter ring valve oil well pump(50), the lower end of the sucker rod(4) and a plunger top of the minor diameter ring valve oil well pump(50) are connected, the plunger bottom of the minor diameter ring valve oil well pump(50) is fixedly provided with the short sucker rod(4).

Description

technical field [0001] The invention relates to an oil pump for a high-inclination horizontal well. Background technique [0002] The oil well pump is widely used in oil production equipment, and the SAGD oil well pump is the abbreviation of the oil well pump for high-temperature and high-inclination horizontal wells. [0003] At the end of the 1980s, foreign countries began to drill and produce horizontal wells. At present, the import price of a complete set of conventional large-scale SAGD oil well pumps designed and manufactured abroad is about 300,000 RMB. Horizontal wells appeared in our country in the early 1990s. At present, the maximum daily output of relatively mature SAGD oil well pumps is 200m3. With the improvement of horizontal well technology, SAGD technology is becoming more and more mature, and the existing horizontal well oil well pump can no longer meet the requirements of oilfield production. Contents of the invention [0004] The purpose of the presen...
