Abstract

The utility model discloses a suspension releasing packer for an oil-gas water well. A central pipe is arranged at the right end of a connecting head; a balancing sleeve is arranged outside the central pipe at the right end of the connecting head; a hydraulic cylinder piston is arranged at the right end of the balancing sleeve; a releasing device is arranged on the inner side of the central pipe; a set packer is arranged at the right end of the hydraulic cylinder piston; a sealing rubber sleeve is arranged at the right end of the set packer; a rubber sleeve seat is arranged at the right end of the sealing rubber sleeve; a self-locking ring is arranged at the right end of the rubber sleeve seat; a slip-type hanger is arranged at the right end of the self-locking ring; a packing eliminating device is arranged at the right end of the central pipe. The suspension releasing packer disclosed by the utility model has the advantages of reasonable design, simple structure, strong impact resistance, good underground safety, convenience for subsequent processing and the like. The suspension releasing packer is simple and convenient for mounting and high in construction operation efficiency and can be popularized and used in an oil field.

Description

Oil gas water well packer
Technical field
The utility model belongs to producing oil, gas, water from well; The method of solubility or solubilization material or slurry of mineral or equipment technical field, be specifically related to a kind of oil gas water well packer.
Background technology
In downhole petroleum operation, packer is conventional oil tool.In petroleum production engineering, packer is used for layering, is designed with oil recovery passage on packer, and while setting, piston bush is up, and oil recovery passage is opened; After setting, upper strata pressure-acting, on dummy piston, upwards pushes away packing element, makes deblocking pin avoid shearing force; During deblocking, by the frictional force of packing element and sleeve pipe, cut off deblocking pin, piston bush is descending, closes oil recovery passage.
The use of packer can realize not open flow operation of not kill-job easily, and can bear upper and lower two-way high pressure and pressure reduction, long service life.But for severe operating environments of construction such as high angle hole, horizontal wells, common downhole packer may occur to set midway, and the environment excessive in impact force easily breaks down, and serious even can affect the development of whole oil reservoir.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of above-mentioned packer, provides that a kind of reasonable in design, simple in structure, strong shock resistance, downhole safety are good, subsequent treatment oil gas water well packer easily.
Addressing the above problem adopted technical scheme is:
At coupling head right-hand member, central tube is set, the central tube arranged outside balance set of coupling head right-hand member, balance set right-hand member arranges liquid cylinder piston, central tube inner side arranges releasing device, and liquid cylinder piston right-hand member arranges set packer, and set packer right-hand member arranges cartridge, cartridge right-hand member arranges glue tube base, glue tube base right-hand member arranges self-locking ring, and self-locking ring right-hand member arranges slips hanger, and central tube right-hand member arranges decapsulator.
Because having adopted balance set right-hand member, the utility model is fixedly connected with liquid cylinder piston by screw thread, the central tube outside of liquid cylinder piston right-hand member is fixedly connected with set packer by screw thread, set packer right-hand member is provided with cartridge, self-locking ring right-hand member is fixedly connected with slips hanger by screw thread, ground high-pressure hydraulic pump is inwardly suppressed liquid from oil pipe, liquid is because the effect promotion liquid cylinder piston of pressure moves, liquid cylinder piston promotes cartridge and slips hanger, slips hanger is opened and set clamping at internal surface of sleeve pipe, realization sets the utility model at internal surface of sleeve pipe, cartridge is opened annular space sealing simultaneously, on during deblocking, carry central tube and can realize deblocking.
It is simple and convenient that the utility model is installed, and construction operation efficiency is high, and the advantage such as have reasonable in design, simple in structure, strong shock resistance, downhole safety is good, subsequent treatment is convenient can be promoted the use of on oil well, gas well, well.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited to these embodiment.
Embodiment 1
In Fig. 1, the oil gas water well of the present embodiment is connected and is formed by coupling head 1, balance set 2, liquid cylinder piston 3, releasing device 4, set packer 5, cartridge 6, glue tube base 7, self-locking ring 8, central tube 9, slips hanger 10, decapsulator 11 with packer.
At coupling head 1 right-hand member, by screw thread, be fixedly connected with central tube 9, central tube 9 inner sides fixedly mount releasing device 4 by screw thread, the commodity of releasing device 4 for selling on market, model is Y441, central tube 9 outsides of coupling head 1 right-hand member are fixedly connected with balance set 2 by screw thread, balance set 2 right-hand members are fixedly connected with liquid cylinder piston 3 by screw thread, liquid cylinder piston 3 inner sides and outside seal with central tube 9 and balance set 2 respectively with packing, central tube 9 outsides of liquid cylinder piston 3 right-hand members are fixedly connected with set packer 5 by screw thread, set packer 5 right-hand members are provided with cartridge 6, set packer 5 outsides of cartridge 6 right-hand members are fixedly connected with glue tube base 7 by screw thread, glue tube base 7 moves left and right for preventing cartridge 6, glue tube base 7 right-hand members are fixedly connected with self-locking ring 8 by screw thread, self-locking ring 8 right-hand members are fixedly connected with slips hanger 10 by screw thread, central tube 9 right-hand members are fixedly connected with decapsulator 11 by screw thread.
While using oil of the present utility model, gas, well with packer operation, ground high-pressure hydraulic pump is inwardly suppressed liquid from oil pipe, liquid is because the effect promotion liquid cylinder piston 3 of pressure moves, liquid cylinder piston 3 promotes cartridge 6 and slips hanger 10, make slips hanger 10 open and set clamping at internal surface of sleeve pipe, realization sets the utility model at internal surface of sleeve pipe, and simultaneously cartridge 6 is opened annular space sealing, carries central tube 9 on during deblocking can realize deblocking.
