Abstract
The utility model relates to a downhole operation device in the oil industry, in particular to an abrasion-proof device for a defueling pump. The technical proposal is as follows: the abrasion-proof device mainly consists of two parts, namely an outer tube part and an inner rod part; an upper seal joint of the inner rod part is connected with a check valve seat, and the lower part of the check valve seat is connected with a pump barrel of the defueling pump; a check valve, a sealing element supporting body, a sealing gum ring, a sealing clamping ring, a sealing clamping cap, a limit spring and a spring seat are in turn sleeved on a sucker rod and on the spring seat; the obturating ring and a breaking pin are fixed in the upper seal joint, and then a butting guide rod cover is sleeved by an external lock casing, wherein a butting spring is connected with a lower joint. The abrasion-proof device has the advantages: firstly the abrasion-proof device can effectively prevent the sand in the crude oil from settling on a piston during the oil pumping process, thereby greatly improving the working environment of the defueling pump, and prolonging the service life of the defueling pump; secondly oil pipe clasps are provided to make the upper and lower parts of the abrasion-proof device be directly connected with an oil pipe, thereby bringing about very convenient operation.
Description
One, technical field:
The utility model relates to a kind of underground work device of petroleum industry, particularly a kind ofly is applicable to the various oil well pump shoes that utilize the oil recovery well of oil well pump.
Two, background technique:
In the nonflowing well oil recovery process in oil field because many oil wells all shake out, the crude oil that promptly utilizes the oil well pump extraction in various degree contain sand because the proportion of sand is bigger, constantly sink at the oil recovery process medium sand, increased the wearing and tearing of pump.In order to solve the oil well pump wear problem, relevant technologies personnel had once designed sand-control pump, long-plunger pump etc., though these schemes have solved some problems to a certain extent, because this problem of wearing and tearing of the pump that the sand that contains in the crude oil sinks to causing fails thoroughly to solve all the time.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of oil well pump shoe is provided, can prevent effectively that pump sand in the crude oil in oil pumping process from sinking on the piston, and then improve the working environment of oil well pump, prolong the working life of pump, solve the oil well pump wear problem in the nonflowing well oil recovery process.
Its technological scheme is: mainly be made up of outer tube part and interior bar part two large divisions, described outer tube part comprises: go up SEALING FITTING, spring seat, cut off pin, seal ring and single current valve seat, described in bar partly comprise: butt joint, butt joint inversion pole, outer lock tube, butt joint spring, lower contact, cut off pin, limit spring, seal pressure cap, seal joint, sealed rubber ring, Sealing support, one-way valve, sucker rod; To go up SEALING FITTING and the single current valve seat links together, the bottom of single current valve seat is connected with the pump barrel of oil well pump; One-way valve, Sealing support, sealed rubber ring, seal joint, seal pressure cap, limit spring and spring seat are sleeved on the sucker rod and on spring seat successively, seal ring also is fixed in the SEALING FITTING with cutting off pin, to dock the inversion pole cover then and load onto the external lock cover, wherein, butt joint spring and lower contact are joined.
Described seal ring is fixed in the SEALING FITTING by cutting off pin.
The utility model compared with prior art has following significant beneficial effect: 1, pump in oil pumping process oil well pump piston and top crude oil in different chamber work, can prevent effectively that pump sand in the crude oil in oil pumping process from sinking on the piston, thereby can improve the working environment of oil well pump greatly, prolong the working life of pump.2, two ends are processed with oil tube buckle, upper and lowerly all can directly link to each other with oil pipe, make Job Operations very convenient.
Four, description of drawings:
Accompanying drawing 1 is the figure that partly cuts open of the present utility model;
Among the figure: butt joint 1, butt joint inversion pole 2, outer lock tube 3, butt joint spring 4, go up SEALING FITTING 5, lower contact 6, spring seat 7, cut off pin 8, seal ring 9, seal ring 10, limit spring 11, seal pressure cap 12, seal joint 13, sealed rubber ring 14, Sealing support 15, one-way valve 16, single current valve seat 17, sucker rod 18.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described: mainly be made up of outer tube part and interior bar part two large divisions; Outer tube part comprises SEALING FITTING 5, spring seat 7, cuts off pin 8, " O " RunddichtringO 9 and 10, single current valve seat 17 etc.; Interior bar partly comprises: butt joint 1, butt joint inversion pole 2, outer lock tube 3, butt joint spring 4, lower contact 6, cut off pin 8, limit spring 11, seal pressure cap 12, seal joint 13, sealed rubber ring 14, Sealing support 15, one-way valve 16, sucker rod 18 etc.
At first the last SEALING FITTING 5 of outer tube and single current valve seat 17 are in the same place by screwed connection during use, and by seal ring 10 sealings, the bottom oil tube buckle with single current valve seat 17 is connected with the pump barrel of bottom oil well pump by oil pipe then; Utilize sucker rod to be connected this moment and be sleeved on one-way valve 16, Sealing support 15, sealed rubber ring 14, seal joint 13, seal pressure cap 12, limit spring 11 and spring seat 7 on the sucker rod successively and on spring seat 7, will go up seal ring 9 and also be fixed in the SEALING FITTING 5 with cutting off pin 8 with the piston of oil well pump, to dock then to overlap on the inversion pole 2 and load onto external lock cover 3, butt joint spring 4 and lean on screw thread and lower contact 6 to join, lower contact 6 at this moment can link together with sucker rod.Can normally be lowered to oil pipe this moment, after having descended in oil pipe butt joint 1 is connected on the sucker rod bottom and is lowered to sucker rod, when the position, slowly transfer sucker rod, press down sucker rod after putting in place, butt joint 1 can be finished automatically and dock under the effect of the butt joint of inversion pole 2 and butt joint spring 4 and finish the locking of outer lock tube 3, on propose the over-stroke construction of can normally pumping.
Oil well pump piston and top crude oil can prevent effectively that pump sand in the crude oil in oil pumping process from sinking on the piston, thereby can improve the working environment of oil well pump greatly in different chamber work in oil pumping process, prolong the working life of pump.
