Abstract
The utility model relates to a sand-stuck prevention pump device used for oil well. The technical scheme includes as follows: the sand-stuck prevention pump device mainly consists of two parts, namely a combined cone body and a combined cone seat; wherein, the combined cone body is formed by two sealing cone bodies and a spring retaining ring; the combined cone seat is formed by two sealing seats and a fixing device of the sealing seat; the sealing cone body is moveably connected with another sealing cone body and the two sealing seats are fixed and form the combined cone body by the spring retaining ring; the sealing seat is moveably connected with the other sealing seat, and the two sealing seats are fixed by the fixing device of the sealing seat and then are lowered to the oil well with a sucker rod together. The sand-stuck prevention pump device has beneficial effects that 1. effectively preventing the sand in the raw oil from sinking on a piston when the pump pumps the oil, especially when the pump stops pumping, thus greatly improving the working environment of a defueling pump, prolonging the service life of the pump and effectively preventing the accident of sticking pump by sand; 2. adopting a separated structure, thereby the sand-stuck prevention pump can be blocked on the sucker rod to work directly, thus facilitating the working operation greatly.
Description
One, technical field:
The utility model relates to a kind of underground work device of petroleum industry, the anti-sand setting holddown device that particularly a kind of oil well that utilizes oil well pump to recover the oil is used.
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 all in various degree contain sand, because the proportion of sand is bigger, constantly sink at the oil recovery process medium sand, the wearing and tearing of pump have been increased, more seriously when stop pumping for various reasons, because the sinking meeting of sand causes pump seizure the accident of sand holddown.In order to solve the oil well pump wear problem, relevant technologies personnel had once designed multiple sand-control pump, though these schemes have solved some problems to a certain extent, but 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, particularly the problem of sand setting holddown more can't solve.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of anti-sand setting holddown device is provided, and solves the sand setting holddown problem in the nonflowing well oil recovery process.
Its technological scheme is: mainly be made up of combination cone and combination tapered seat two large divisions, two seal cones, spring flanges wherein making up cone and be by ring combine, and the combination tapered seat is to be formed by two sealing seats, sealing seat fixing device combination; Seal cones and another seal cones are flexibly connected, and form admittedly in conjunction with cone with spring flange, sealing seat and another sealing seat are flexibly connected, by the sealing seat fixing device sealing seat and another sealing seat are fixed together then, in the sucker rod lower going-into-well.
Preferred scheme is: described seal cones is provided with boss, and another seal cones is provided with the groove that matches with boss; Sealing seat is provided with boss, and another sealing seat is provided with the groove that matches with boss; The boss of seal cones is inserted in the groove of seal cones, and forms admittedly in conjunction with cone, the boss of sealing seat is inserted in the groove of sealing seat with spring flange.
In addition, described sealing seat fixing device utilizes screw thread that two sealing seats are fixed together.
The utility model compared with prior art has following significant beneficial effect:
1, since the utility model make pump in oil pumping process oil well pump piston and top crude oil in different chamber work, can effectively prevent pump in oil pumping process particularly during stop pumping the sand in the crude oil sink on the piston, thereby can improve the working environment of oil well pump greatly, prolong the working life of pump, and can effectively prevent the generation of sand holddown accident; 2, the utility model adopts split-type structural, can directly be stuck on the sucker rod and work, and makes Job Operations very convenient; 3, this device can freely remove with sucker rod, neither influences other operation, also can not bring other any additional work amount to operation.
Four, description of drawings:
Accompanying drawing 1 is the figure that partly cuts open of the present utility model;
Accompanying drawing 2 is A-A sectional views of the present utility model;
Accompanying drawing 3 is B-B sectional views of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described: mainly be made up of combination cone and combination tapered seat two large divisions, two seal cones 1,3, the spring flange 2 that wherein make up cone and be by ring combine, and the combination tapered seat is to be combined by two sealing seats 4,5, sealing seat fixing device 6; Wherein sealing seat fixing device 6 is to be combined by sealing seat skeleton and vulcanized rubber.
With reference to accompanying drawing 2 and 3, an above-mentioned seal cones 3 is provided with boss, and another seal cones 1 is provided with the groove that matches with boss, and sealing seat 5 is provided with boss, and sealing seat 4 is provided with the groove that matches with boss; At first the half slot of seal cones 1 is close in use on the sucker rod, then the half slot of seal cones 3 is close on sucker rod, the boss of seal cones 3 is inserted in the groove of seal cones 1, and form in conjunction with cone with spring flange 2 is solid, half slot with sealing seat 4 is close on sucker rod then, and the boss of sealing seat 5 is inserted in the groove of sealing seat 4.In addition, described sealing seat fixing device 6 utilizes screw thread that sealing seat 4 and sealing seat 5 are fixed together, in the sucker rod lower going-into-well till piston is lowered to the design attitude of pump barrel.
Certainly, above-mentioned two seal cones 1,3 also can adopt similar fashion well-known to those skilled in the art to be connected with the Placement of two sealing seats 4,5, belong to the claimed scope of the utility model to the greatest extent.
After following having bored, on propose the operation of can pumping behind certain over-stroke, working principle of the present utility model is: when the piston of pump enters pump barrel since the external diameter of sealing seat fixing device greater than the internal diameter of pump barrel, so the sealing seat fixing device will be stayed outside the pump barrel and because the sealing seat fixing device is vulcanized rubber is arranged, so can play the effect of sealing pump barrel.
Concrete working procedure is: when the oil pumping upstroke, liquid will be taken out at pump and will make up cone under the pressure effect and lift, liquid by the combination tapered seat liquid chunnel and along the outflow that makes progress of the annular space of combination cone and oil pipe; When the oil pumping down stroke, the combination cone can enter the combination tapered seat again and seal under the double action of gravity and fluid pressure, and the combination tapered seat is again by vulcanized rubber sealing pump barrel.Therefore can prevent effectively that the sand in the liquid from entering pump barrel.
When needs are examined pump, on carry sucker rod, this model utility will be tripped out ground together with sucker rod, can not have any impact to flow chart.
