Abstract
The utility model provides a high-efficient ring-sealed oil well pump, which comprises a long plunger, glands and a bottom valve assembly, the long plunger is arranged in the middle of the oil well pump, the glands are arranged on both sides of the long plunger, the bottom valve assembly is arranged on the bottom of the oil well pump, and according to different well conditions, the length of the long plunger is between 3.6m and 7.5m; the gland comprises a ring box and twelve sets of sealing rings, wherein the twelve sets of sealing rings include two sets of hard rings and ten sets of soft rings, two sets of elastic restricting and sand-resisting rings are respectively mounted in the upper and the lower ends of the ring box, and ten sets of elastic soft sealing rings are mounted in the middle, and are made of polymer material; and the upper part of the fixed valve of the bottom valve assembly is provided with a rotary sand-preventing sunken tube, which can prevent sand from falling into the valve seat to cause the failure of the seat. The utility model has the advantages that: because of the structural characteristics and different sealing materials of the high-efficient ring-sealed oil well pump, the high-efficient ring-sealed oil well pump is characterized by elastic abrasion compensation, and is adapted to various pump setting depths.
Description
Technical field
The utility model relates to a kind of oil well pump, is specifically related to a kind of efficient ring seal oil well pump.
Background technique
Along with deepening continuously that oil field prospecting is developed, the difficulty of oil field later stage oil extraction is increasing at present.The oil field stratum energy weakens, and producing fluid level is low, and is high moisture, and it is serious to shake out.Conventional oil well pump is difficult to adapt to oil field development, the requirement of stable and high yields.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of efficient ring seal oil well pump.
Technical solution adopted in the utility model is: a kind of efficient ring seal oil well pump, form by long-plunger, stuffing box gland, bottom valve assembly, the middle part of oil pump is provided with long embolism, the both sides of long embolism are provided with stuffing box gland, the bottom of oil pump is provided with the bottom valve assembly, according to the length of the different long-plungers of hole condition between 3.6m-7.5m.
Stuffing box gland is made up of ring box and 12 groups of seal rings, and the hard ring of two covers is wherein arranged, and the soft ring of 10 covers is respectively adorned one group of elasticity throttling resistance sand ring in the two ends up and down of ring box, and 10 groups of elastic soft sealing rings are equipped with at the middle part, and this group ring adopts macromolecular material.
The bottom valve assembly is furnished with rotary type sand control immersed tube on standing valve top, prevent that the gravel junk from falling into valve seat and making base malfunctioning.
The beneficial effects of the utility model are: efficient ring seal oil well pump is because its structural feature and sealing material different have the characteristics of elastic compensating wearing and tearing, suitable various pump setting depths.
