Abstract
The utility model relates to an oil-well pump that uses on oil field oil pumping well, especially a multifunctional oil-well pump, owing to adopted lower valve seat 8, the valve body 9, the fixed valve body 10, fixed valve seat 11, sealed pipe 12, jump ring 13, the spacing body 14, the spacing body 16 of piston, short circuit 17 and piston ring 18 under the pump, make it except having general tubular pump oil pumping function, can also propose the pump barrel with the piston through hanging the direct sand washing of back, sand washing pipe post need not descend again, when the pump efficiency descends and needs to examine the pump, as long as propose the piston and change the piston ring go down can reach and examine the pump effect, this pump play piston alright make the tubular column draining reduce pollution, it is effectual to go out serious well sand blocking of sand, it is efficient to pump oil.
Description
The utility model relates to a kind of oil well pump that uses on a kind of oil field pumping well, particularly a kind of multifunctional oil-well pump.
The tubing pump that generally uses on the present oil-field oil pumper, because its sand control card poor performance, the pipe column oil drainage difficulty causes ground pollution serious, and can not be with pump sand washing, complicated operation.
The purpose of this utility model is to provide a kind of multifunctional oil-well pump, can make pipe column oil drainage, directly sand washing, and sand control card effect is better, the pumping efficiency height.
The purpose of this utility model is to realize like this, it is by linkage connector 1, solid connecting rod 2, upper connection 3, working barrel 4, piston joint 5, piston oil drainage hole 6, piston 7, following valve seat 8, valve body 9, standing valve body 10, standing valve seat 11, sealing duct 12, jump ring 13, limit body 14, pressed joint 15, piston limit body 16, short circuit 17 and piston ring 18 are formed under the pump, linkage connector 1 is connected with solid connecting rod 2, is connected to piston limit body 16 successively on the solid connecting rod 2, piston joint 5, piston oil drainage hole 6, piston 7, following valve seat 8, valve body 9, standing valve body 10, sealing duct 12, jump ring 13; Pump barrel is to be connected with working barrel 4 by upper connection 3, is connected to short circuit 17 under pressed joint 15, the pump successively, is welded with standing valve seat 11, limit body 14 on pressed joint.On piston 7, be embedded with piston ring 18.
When the pumping unit up stroke, connecting rod 2 drives standing valve body 10 and valve body 9 moves upward, this moment, standing valve seat 11 was opened by friction, sealing envelope conduit 12, jump ring 13, limit body 14 control valve bodies open height, connecting rod 2 upwards does relative motion with sealing duct 12, liquid is inhaled in the pump barrel, and valve body 9 moves upward with following valve seat 8 sealings and drive piston 7, and piston 7 upper liquids are discharged; When the pumping unit down stroke, connecting rod 2 moves downward, and drives piston limit body 16 and contacts with piston joint 5, force piston to move downward, this moment, valve body 9 separated with following valve seat 8, and pump standing valve body 10, standing valve seat 11 are closed, liquid is inhaled in the piston, thereby finishes a working procedure; When the needs sand washing, piston is proposed the pump work tube hang, can be with the pump sand washing, finish draining during lift pipe string automatically, the gap that 18 compensating pistons of piston ring and the friction of pump work tube increase is to improve the working efficiency of pump.
The utility model is owing to adopted time valve seat 8, valve body 9, standing valve body 10, standing valve seat 11, sealing duct 12, jump ring 13, limit body 14, piston limit body 16, short circuit 17 and piston ring 18 under the pump, make it except that having general tubing pump oil pumping function, pump barrel directly sand washing after hanging piston can also be proposed, need not descend the sand washing tubing string again, when pump efficiency decline needs the inspection pump, as long as piston is proposed more rering to be lowered to and can to reach inspection pump efficiency fruit, this pump trips out piston just can make pipe column oil drainage, reduce and pollute, serious well sand control card is effective for shaking out, the pumping efficiency height.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
The utility model is made up of 18 kinds of parts, each part dimension is linkage connector 1 φ 46 * 120, solid connecting rod 2 φ 22 * 4200, upper connection 3 φ 62 * 180, working barrel 4 φ 60 * 5000, piston joint 5 φ 46 * 120, piston oil drainage hole 6 φ 10 * 4, piston 7 φ 60 * 1200, following valve seat 8 φ 57 * 30, valve body 9 φ 56 * 45, standing valve body 10 φ 57 * 45, standing valve seat 11 φ 58 * 45, sealing duct 12 φ 52 * 500, jump ring 13 φ 55, limit body 14 φ 54, pressed joint 15 φ 107 * 200, piston limit body 16 φ 46 * 100, short circuit 17 φ 88.9 * 1500 and piston ring 18 are formed under the pump, external dimension are φ 73 * 5000, working pressure: 10MPa, stroke are 3 meters.
