Abstract
The utility model relates to an oil extraction device, in particular to a novel extraction tubular column of an oil field. According to the technical scheme, the novel extraction tubular column of the oil field comprises a gas-lift valve, a sliding sleeve, a packer, a sleeve tube, an oil tube, a sand prevention tube and a centering guide, wherein the oil tube is fixed in the sleeve tube, the oil tube is provided with the packer and the sliding sleeve, the sand prevention tube is arranged at the tail end of the oil tube, and the centering guide is arranged between the oil tube and the sleeve tube. The novel oil extraction tubular column of the oil field has the advantages of improving the working performance in the oil field, solving the problem caused by failure of the packer, and prolonging the service life of the equipment.
Description
Technical field
The utility model relates to a kind of extracting device of oil, particularly a kind of novel oilfield flow string.
Background technology
In the oil extraction process, because the impact of the factors such as oil reservoir structure, crude oil property, formation water composition, extracting device of oil must adapt to the requirement of various oil reservoirs such as shaking out, the content of wax, aqueous corrosion, oil are thick.And along with the progress of drilling technology, the exploitation of the exploitation of platform well group and inclined shaft and horizontal well production technology, there are the following problems aborning for the novel oilfield flow string: admission data difficulty, packer easily lost efficacy; The large grains of sand and trouble of lost tool in hole in the oil reservoir of down-hole easily enter the hydraulic jet pump pump housing, cause pump to lose efficacy cisco unity malfunction.
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 oilfield flow string is provided, and has improved oil well operation efficient.
Its technical scheme is: comprise gas lift valve, sliding sleeve, packer, sleeve pipe, oil pipe, sand-proof pipe, centralizer, inside pipe casing is oil pipe fixedly, and oil pipe is provided with packer and sliding sleeve, and the end of oil pipe is provided with sand-proof pipe, is provided with centralizer between oil pipe and the sleeve pipe.
Connect by telescoping tube between the above-mentioned oil pipe.
The beneficial effects of the utility model are: improved oil well operation efficient, the problem of having avoided packer to lose efficacy and bring has prolonged application life of equipment.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: gas lift valve 1, telescoping tube 2, sliding sleeve 3, packer 4, sleeve pipe 5, oil pipe 6, sand-proof pipe 7, centralizer 8.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises gas lift valve 1, sliding sleeve 3, packer 4, sleeve pipe 5, oil pipe 6, sand-proof pipe 7, centralizer 8, sleeve pipe 5 inner fixedly oil pipes 6, oil pipe 6 is provided with packer 4 and sliding sleeve 3, and the end of oil pipe 6 is provided with sand-proof pipe 7, is provided with centralizer 8 between oil pipe 6 and the sleeve pipe 5; Connect by telescoping tube 2 between the described oil pipe 6.
During operation, provide working material by gas-lift working barrel for gas lift valve, the two consists of an integral body control air-flow, reach the purpose of lifting down-hole liquid, sliding sleeve is mainly tubing string circulation canal is provided, and is used for kill-job or well-flushing, put on the packer to put and set, prevent that sleeve pipe from bearing high pressure, the distribution of gas lift valve mainly is subjected to air supply system starting pressure, well killing fluid gradient, the impact of the factors such as gas injection rate, stratum feed flow.
