Abstract
The utility model discloses a sand control prevents stifled tubular oil-well pump, by the direction coupling, the outer tube, become through the coupling, the bridge type nipple joint, the pump barrel, pump barrel extension pipe, the connector, prevent the foreign matter outer tube, plunger assembly and fixed ball valve are constituteed, at the fixed valve seat, through a threaded connection nipple joint under the bonnet, the lower extreme and the bridge type nipple joint threaded connection of this nipple joint, the external diameter of bonnet and nipple joint all is less than the internal diameter of preventing the foreign matter outer tube, constitute annular storage bag B between bonnet and nipple joint and prevent the foreign matter outer tube, this pump can effectively prevent junk and sand setting jam standing valve, the pump cycle is examined in the extension, oil-well pump life is improved.
Description
The utility model relates to the anti-blocking tubing pump of a kind of sand control, belongs to the oil well pump that uses in the oil recovery exploitation of oil field, and being specially adapted to has the oil well pump that foreign matter, sand material are arranged in junk and the well in oil recovery well operation and the oil recovery process.
At present, in oil field development is produced, use mainly be the tubular type sand-proof oil-well pump, following defective is arranged in use: 1, during the oil well operation, well site silt particle, tube inner wall scale or other foreign matters fall into the standing valve place, and valve cuts out, cause the oil well pump card stifled, need well-flushing or heavily go up operation; 2, in the oil recovery process,, also can be deposited on the standing valve place, cause feed flow not enough and block when serious if foreign matter such as sand grains is arranged in the fluid column in the oil well pump pump barrel; 3, the compressing structure of fixed valve base is unreasonable, causes leakage in the oil well pump short time easily and loses efficacy.
The purpose of this utility model is in order to overcome the defective of tubular type sand-proof oil-well pump in the prior art, design a kind of can the sand control card, can prevent that again standing valve is blocked, the anti-blocking tubing pump of the sand control of long service life.
The purpose of this utility model is achieved in that
The utility model is by drive ring, outer tube, change is through box cupling, the bridge-type pipe nipple, pump barrel, the pump barrel extension pipe, connecting head, anti-foreign matter outer tube, plunger piston assembly and fixing ball valve are formed, drive ring, outer tube, change is through box cupling, be threaded successively, pump barrel, the pump barrel extension pipe, connecting head, anti-foreign matter outer tube, the bridge-type pipe nipple is threaded successively, plunger is by last, under the ball valve that moves about, plunger body, upper travelling valve joint and lower travelling valve pressure cap connect and compose by rib-loop, fixing ball valve is by fixed valve ball, fixed valve base, valve bonnet is formed, fixed valve base, under the valve bonnet by the pipe nipple that is threaded, the lower end of pipe nipple is threaded with the bridge-type pipe nipple, all less than the internal diameter of anti-foreign matter outer tube, looping stores up bag B to the external diameter of valve bonnet and pipe nipple between valve bonnet and pipe nipple and anti-foreign matter outer tube.
The utility model compared with prior art has following advantage:
1, during the oil well operation, well site silt particle, tube inner wall scale or other foreign matter fall in the oil well pump, do not need anti-flushing well after operation is finished;
2, in the oil recovery process, foreign matter such as sand grains will sink between valve bonnet and pipe nipple and anti-foreign matter outer tube among the looping storage bag B in the well, standing valve can not blocked, and can prolong the life cycle of oil well pump.
Fig. 1: the utility model structural representation;
Among the figure: the 1-upper traveling valve cage, 2-upper travelling valve ball, 3-upper travelling valve seat, 4-upper travelling valve joint, the 5-drive ring, the 6-plunger body, the 7-pump barrel, the 8-centering ring, the 9-outer tube, 10-pump barrel extension pipe, 11-lower travelling valve cover, 12-lower travelling valve ball, 13-lower travelling valve seat, 14-lower travelling valve pressure cap, the 15-connecting head, 16-prevents the foreign matter outer tube, the 17-fixed valve ball, the 18-fixed valve base, the 19-standing valve cover, connect pipe nipple under the 20-fixing ball valve, 21-bridge-type pipe nipple, 22-becomes through box cupling, the 23-helmet.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model is by drive ring 5, outer tube 9, change is through box cupling 22, bridge-type pipe nipple 21, pump barrel 7, pump barrel extension pipe 10, connecting head 15, anti-foreign matter outer tube 16, plunger piston assembly and fixing ball valve are formed, drive ring 5, outer tube 9, change is through box cupling 22, be threaded successively, pump barrel 7, pump barrel extension pipe 10, connecting head 15, anti-foreign matter outer tube 16, bridge-type pipe nipple 21 is threaded successively, plunger is by last, under the ball valve that moves about, plunger body 6, upper travelling valve joint 4 and lower travelling valve pressure cap 14 are by the formation that is threaded, fixing ball valve is by fixed valve ball 17, fixed valve base 18, valve bonnet 19 is formed, fixed valve base 18, valve bonnet 19 times is by the pipe nipple 20 that is threaded, the lower end of pipe nipple 20 is threaded with bridge-type pipe nipple 21, the external diameter of valve bonnet 19 and pipe nipple 20 is all less than the internal diameter of preventing foreign matter outer tube 16,16 looping storages of valve bonnet 19 and pipe nipple 20 and anti-foreign matter outer tube bag B, in addition, valve bonnet 19 upper end closeds, sidepiece has oil through.
The oil well pump that the ground pressure testing is qualified is lowered in the oil well by designing requirement, when arriving design attitude, fixing ball valve is in closed condition, then, sucker rod drive plunger is lowered in oil well pump pump barrel 7 and the pump barrel extension pipe 10 then, in being lowered to process, in pit shaft silt particle or tube inner wall scale the valve bonnet 19 and pipe nipple 20 and 16 looping storages of anti-foreign matter outer tube bag B, having solved the oil well pump normal operation and prevented that effectively the well head junk from stopping up the problem of fixing ball valve with regard to the oil well pump fixing ball valve; During the oil well pump proper functioning, plunger is when last initial point, foreign matter in the fluid column in the pump barrel such as sand grains drop to the top of fixing ball valve valve bonnet 19 and on every side, and valve bonnet 19 tops are sealed, so, foreign matter also can be deposited among valve bonnet 19 and pipe nipple 20 and 16 looping storages of the anti-foreign matter outer tube bag B in the well, prevented that effectively the interior foreign matter of well from blocking the generation of the problem of fixing ball valve, thereby, realized not needing well-flushing after the operation, oil well pump can not blocked during proper functioning, the phenomenon that is blocked, the working life of having improved oil well pump, prolong pump detection period, reduced cost of production.
