Abstract
The utility model relates to a borehole operation device, and in particular relates to a sand control device for an oil well. The technical scheme is that the sand control device for the oil well comprises a hoisting ring, a high pressure hose, an oil pipe, a packer, a centering device, a sleeve, a rotary spray head, a plug and a joint, wherein the oil pipe is arranged in the sleeve; the hoisting ring is connected to the top part of the oil pipe by the joint; the high pressure hose is arranged on one side of the joint; the packer is arranged in the part where the oil pipe is connected with the sleeve; the centering device is arranged between the oil pipe and the sleeve; the rotary spray head is connected to the bottom of the oil pipe; and the plug is arranged at the bottom of the sleeve. The sand control device for the oil well has the beneficial effects that the accident that a pipe column is blocked by sand can be effectively prevented from occurring, the working condition of an oil pump is greatly improved, the service life of a pump is prolonged, the production efficiency of an oilfield is increased, and the cost is decreased.
Description
Technical field
The utility model relates to a kind of underground work device, particularly a kind of sand controller of oil well.
Background technology
In the nonflowing well oil recovery process in oil field, because many oil wells all shake out, the crude oil that namely utilizes the oil well pump extraction in various degree contain sand, because the proportion of sand is larger, constantly sink at the oil recovery process medium sand, increase the wearing and tearing of pump, if because various factors causes power failure, very easily caused the generation of holddown accident.In order to solve the oil well pump wear problem, relevant technologies personnel once were designed with sand-preventing pump, centre long plunger pump etc., though these schemes have solved some problems to a certain extent, for pump because the sand card problem that power failure causes still can not solve.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of sand controller of oil well is provided, and effectively prevents the generation of sand card tubing string accident.
Its technical scheme is: comprise suspension ring, high-pressure hose, oil pipe, packer, centralizer, sleeve pipe, rotary nozzle, plug, joint, the inside of sleeve pipe is provided with oil pipe, the top of oil pipe connects suspension ring by joint, one side of joint is provided with high-pressure hose, the junction of oil pipe and sleeve pipe is provided with packer, be provided with centralizer between oil pipe and sleeve pipe, the bottom of oil pipe connects rotary nozzle, and the bottom of sleeve pipe is provided with plug.
The beneficial effects of the utility model are: effectively prevent the generation of sand card tubing string accident, greatly improve the working environment of oil well pump, extend the application life of pump, improve production efficiency of oilfields, Cost reduction.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: suspension ring 1, high-pressure hose 2, oil pipe 3, packer 4, centralizer 5, sleeve pipe 6, rotary nozzle 7, plug 8, joint 9.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises suspension ring 1, high-pressure hose 2, oil pipe 3, packer 4, centralizer 5, sleeve pipe 6, rotary nozzle 7, plug 8, joint 9, the inside of sleeve pipe 6 is provided with oil pipe 3, the top of oil pipe 3 connects suspension ring 1 by joint 9, one side of joint 9 is provided with high-pressure hose 2, oil pipe 3 is provided with packer 4 with the junction of sleeve pipe 6, be provided with centralizer 5 between oil pipe 3 and sleeve pipe 6, the bottom of oil pipe 3 connects rotary nozzle 7, and the bottom of sleeve pipe 6 is provided with plug 8.
The utility model effectively prevents the generation of sand card tubing string accident, greatly improves the working environment of oil well pump, extends the application life of pump, improves production efficiency of oilfields, Cost reduction.
