Abstract
The utility model relates to a tool for oil-well operation, in particular to a novel tubular column for oil-well operation. According to the technical scheme, the novel tubular column for the oil-well operation comprises a casing, an oil pipe, a flexible tubular column compensator, a hydraulic anchor, a packer, a spiral sieve pipe, a seat seal ball valve and a fixed oil pipe in the casing, wherein the flexible tubular column compensator, the hydraulic anchor and the packer are sequentially arranged on the oil pipe from top to bottom; the spiral sieve pipe is arranged on the lower portion of the packer; and the seat seal ball valve is arranged on the bottom of the oil pipe. The novel tubular column for the oil-well operation has the advantages that the tubular column is prevented from being jammed by sand, the working environment of an oil-well pump is greatly improved, the service life of the tubular column is prolonged, the production efficiency of an oil field is improved, and the cost is reduced.
Description
One, technical field
The utility model relates to a kind of oil well operation instrument, particularly a kind of Novel oil well working string.
Two, background technology
In the nonflowing well oil recovery process in oil field, because many oil wells all shake out, the crude oil that utilizes oil well pump extraction in various degree containing sand, because the proportion of sand is larger, at oil recovery process medium sand, constantly sink, 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 oil well pump wear problem, relevant technologies personnel were once 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.
Three, 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 Novel oil well working string is provided.
Its technical scheme is: comprise sleeve pipe, oil pipe, pipe column expansion compensator, hydraulic anchor, packer, spiral screen casing, setting ball valve, inside pipe casing is oil pipe fixedly, described oil pipe is provided with pipe column expansion compensator, hydraulic anchor, packer from top to bottom successively, the bottom of described packer is provided with spiral screen casing, and the bottom of described oil pipe is provided with setting ball valve.
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 tubing string, improve production efficiency of oilfields, reduce cost.
Four, accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: sleeve pipe 1, oil pipe 2, pipe column expansion compensator 3, hydraulic anchor 4, packer 5, spiral screen casing 6, setting ball valve 7.
Five, the specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises sleeve pipe 1, oil pipe 2, pipe column expansion compensator 3, hydraulic anchor 4, packer 5, spiral screen casing 6, setting ball valve 7, the inner fixedly oil pipe 2 of sleeve pipe 1, described oil pipe 2 is provided with pipe column expansion compensator 3, hydraulic anchor 4, packer 5 from top to bottom successively, the bottom of described packer 5 is provided with spiral screen casing 6, and the bottom of described oil pipe 2 is provided with setting ball valve 7.
In use procedure, this device can effectively prevent the generation of sand card tubing string accident, greatly improves the working environment of oil well pump, extends the application life of tubing string, improves production efficiency of oilfields, reduces cost.
