Abstract
The utility model relates to a high-efficient oil-well pump, which is composed of a cylindrical pump shell body and a plunger piston body mounted in movable fit inside the cylindrical pump shell body. The plunger piston body is formed by the connection, from top to bottom, of an upper connector, an upper one-way valve, an upper sealing member of the plunger piston, a lower one-way valve, a lower sealing member of the plunger piston and a lower connector of the plunger piston; the upper one-way valve and the lower one-way valve are righting sphere cores arranged on the upper seat of a ball seat in the plunger piston body; an oil outlet is disposed on the plunger piston body of the one-way valve; an alloy sealing ring and a magnetic fluid storage sealing ring are sleeved at the periphery of the pipe bodies of the upper sealing member and the lower sealing member of the plunger piston. The oil-well pump has the advantages of reasonable design, good sealing effect, no leakage, reduced oil extraction cost, increased pumping efficiency and prolonged pump inspection cycle.
Description
Technical field
The utility model belongs to oil field equipment, particularly relates to a kind of efficient oil-well pump.
Background technique
Oil well pump is the special device of oil field operation, and most oil well pumps belongs to the sealing of area gap type, exists bigger wastage, makes pump efficiency lower, generally have only 50～60%, simultaneously, during again owing to the oil well pump descent of piston, descending by the sucker rod own wt, because piston is longer, make to produce descending resistance between it and the oil well pump, make rod sag, form loss of plunger stroke and reduce pump efficiency.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and the efficient oil-well pump of a kind of short column plug, low friction resistance, the complementary sealed type of multistage mixing is provided.
Efficient oil-well pump of the present utility model is to have installed the plunger body formation in the cylindrical pump housing movingly additional, and plunger body is to be connected and composed by seal, following one-way valve, plunger lower seal body, plunger lower union joint on upper binding head, last one-way valve, the plunger from top to bottom successively.
As further improvement of the utility model, described upward one-way valve and following one-way valve are that the rod-type sphere core is set upright at the ball seat seat of honour in tube column, on the tube column of one-way valve oil outlet are arranged.
As further improvement of the utility model, the body periphery of seal and plunger lower seal body is with alloy seal ring and magnetic current matter storage seal ring on the plunger.The hybrid multistage complementary sealed plunger of alloy seal ring and magnetic current matter storage seal ring, can make plunger body, pump case gap reach zero leakage, the plunger body endoporus adopts big runner, the one-way valve area of passage increases, plungers length can shorten to 400～500mm in addition, surface friction drag reduces, and can reach the minimizing energy consumption, improves the effect of pump efficiency.
As further improvement of the utility model, on the plunger lower union joint, filler opening is arranged.
As further improvement of the utility model, the section of magnetic current matter storage seal ring is
Shape constitutes the internal memory storage tank, on its ring wall open-work is arranged.
As further improvement of the utility model, on seal on the plunger and plunger lower seal body, all be with more than one magnetic current matter storage seal ring.
Efficient oil-well pump of the present utility model is reasonable in design, good sealing effect does not have leakage, reduce cost for oil production, improve pump efficiency, prolong pump detection period.
Description of drawings
Figure of description is the structural representation of efficient oil-well pump of the present utility model.
Embodiment
Efficient oil-well pump of the present utility model is to have installed plunger body 2 movingly additional to constitute in cylindrical pump housing 1, plunger body 2 is to be connected and composed by seal 5, following one-way valve 6, plunger lower seal body 7, plunger lower union joint 8 on upper binding head 3, last one-way valve 4, the plunger from top to bottom successively, and filler opening 14 is arranged on the plunger lower union joint 8.Last one-way valve 4 wherein and following one-way valve 6 are that rod-type sphere core 10 is set upright at ball seat 9 seats of honour in tube column, and oil outlet 11 is arranged on the tube column of one-way valve 4.The body periphery of seal 5 and plunger lower seal body 7 all is with alloy seal ring 12 and more than one magnetic current matter storage seal ring 13 on the described plunger, and the section of magnetic current matter storage seal ring 13 is
Shape constitutes internal memory storage tank 15, and open-work 16 is arranged on its ring wall.Can also can unite use by a plurality of one-way valves with an one-way valve in plunger body, one-way valve all adopts quick exhaust check valve.The plunger body outer surface adopts the alloy seal ring and the magnetic current matter storage seal ring of hybrid multistage complementation, material adopts different materials such as this special envelope, special rubber, wherein magnetic current matter storage seal ring adopts clock bowl formula seal ring, make plunger, pump case gap reach zero leakage, rigid alloy seal ring is adopted at two ends at magnetic current matter storage seal ring, to reach complementation, increases the service life, can reach the effect of strike-ofing again, prevent the sand card.This pump belongs to multifunctional oil-well pump, and it can be used on viscous crude, thin oil, contains cured, as to contain sand drain oil well pump, is more suitable for water drive, poly-displacement of reservoir oil well, and this pump is owing to the pump efficiency height, and the oil well pump of big pump diameter can substitute with little No. one oil well pump, and reduces energy consumption.
