Abstract
The utility model relates to an oil recovery packer. According to the technical scheme, the lower end of a connector is connected with an upper connector of a central tube through threads, a shear ring is fixed to the upper end of the connector, a rubber sleeve is fixed outside the central tube, and the two ends of the rubber sleeve are fixed through an upper vertebra body and a lower vertebra body respectively. The outside of the upper vertebra body is fixed through an upper slip, and the outside of the vertebra body is a lower slip. The connected position of the connector and the centre tube are fixed through a locking ring. A T-shaped valve is fixed to the lower portion of the shear ring inside the connector. The oil recovery packer can work for a long time, time and labor are saved in the working process, working efficiency is effectively improved, annular spaces between packing tubular piles and a well and between the tubular piles are packed through adjusting the T-shaped valve to open or close, and a production layer is isolated, so that a downhole tool of a sleeve is protected.
Description
Technical field
The utility model relates to a kind of oil production equipment, particularly a kind of oil recovery packing device.
Background technology
Along with oil field is constantly developed, stratum energy is more and more less.In order to keep stratum energy constant, most of well all adopts the mode of water filling to come constantly to stratum makeup energy, and current most of well has entered high water-cut development period.In order to improve oil recovery factor, stratified injection water technology more and more comes into one's own.At present, domestic conventional completion tubular column generally adopts retrievable packer, and its significant deficiency cannot work long hours exactly and also want deblocking packer in the time of maintenance oil well, after having overhauled, is again lowered to, and wastes time and energy.
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 oil recovery packing device is provided, and can realize and working long hours, and works time saving and energy saving, has effectively improved operating efficiency.
Its technical scheme is: comprise joint, shearing ring, lock ring, upper slips, upper centrum, central tube, gum cover, hypocentrum, lower slips, T-valve, the lower end of joint is threaded connection the top connection of central tube, the upper end fixed shear ring of described joint, the external stability gum cover of described central tube, the two ends of described gum cover are fixed by upper centrum and hypocentrum respectively, the outside of upper centrum is fixed by upper slips, the outside of hypocentrum is fixed by lower slips, described joint and the junction of central tube are fixed by lock ring, the fixing T-valve in bottom of described joint internal shear ring.
Above-mentioned T-valve comprises horizontal cavity, longitudinal cavity, laterally a side of cavity connects longitudinal cavity, longitudinally cavity is positioned at the centre of horizontal cavity, described horizontal inside cavity is provided with spool, described spool comprises spring, valve rod, circular piston, spring base, and the top of valve rod connects circular piston, and inside and one end that circular piston is fixed on horizontal cavity connect valve rod, the other end of valve rod is provided with spring base, between spring base and circular piston, is provided with spring.
The beneficial effects of the utility model are: can realize and working long hours; work time saving and energy saving; effectively improve operating efficiency; by regulating opening or closing of T-valve; annular space between packing tubing string and well and between tubing string; and isolated producing zone; the downhole tool of protective casing; move and realize horizontal cavity, the longitudinally conducting of cavity by spool; in the time that spool is positioned at the left side of longitudinal cavity; circular piston can effectively be realized the sealing of horizontal cavity, plays the effect of effective guarantee sealing.
