Abstract
The utility model discloses a suspending packer for separate-layer sand control filter sand pipe, which comprises an upper and a lower joint and an external cylinder sleeve connected between the two joints, a relief short-circuit, a piston, a central pipe, a glue cylinder and its upper and lower press caps, an upper cone, a slips cylinder and its slips and an upper and a lower core pipe, etc. In addition, the packer also comprises a locking device and a detaching gear connected to the central pipe; wherein, the locking device comprises a supporting coupling connected with the upper and the lower core pipe, a locking jaw sleeve linked with the lower cone and a connecting sleeve connected with the locking jaw sleeve with one end and connected with the lower joint with another end; the detaching gear comprises the connecting sleeve, the lower cone connected to the connecting sleeve and a locking ring arranged on top of the lower joint and inside the annular between the connecting sleeve and the locking jaw sleeve. The utility model, with the locking device and the detaching gear adopted, enhances the operation speed, shortens the construction period and lowers the operation cost, which is applicable in the sand protection technics for petroleum extraction.
Description
One, technical field,
The utility model relates to packer, particularly a kind of selective sand control sand screen hanging packer.
Two, background technology
Existing selective sand control sand screen hanging packer mainly exists in the packer set process easily deblocking and seat and is honored as a queen and is difficult for deblocking, salvages difficulty, need go up overhaul sometimes, causes problems such as operating speed is slow, cost height.
Three, summary of the invention
The technical problems to be solved in the utility model is that one of design prevents that seat is difficult for the locking device of deblocking and the trip gear of help deblocking when sealing.
The technical scheme that the utility model is dealt with problems is a kind of improved selective sand control sand screen hanging packer, comprise upper and lower joint and outer cylinder sheath, pressure release short circuit, piston, central tube, packing element and the upper and lower pressure cap thereof, upper cone, slips tube and the slips that connect, upper and lower core pipe etc. therebetween, also comprise the locking device and the trip gear that are connected on the central tube, described locking device comprises that the support box cupling that connects upper and lower core pipe, the lock pawl cover that links to each other with lower cone are connected lock pawl cover with an end, and the other end connects the adapter sleeve of lower contact; Described trip gear comprises described adapter sleeve, is connected in the lower cone of this adapter sleeve one end and is placed in the lower contact top, the locking ring between adapter sleeve and the lock pawl cover in the annular space.
Wherein, the middle part of described lock pawl cover and bottom are provided with evagination lock pawl.
Wherein, described adapter sleeve is provided with inner groove, matches with described evagination lock pawl.
Wherein, described support box cupling two ends respectively connect upper and lower core pipe, and external surface contacts with lock pawl inner surface and supports mutually, and its lock pawl is locked in the described inner groove of adapter sleeve.
The utility model has following advantage compared with prior art:
1, adopted locking device, the lock pawl that the lock pawl is put makes it lock mutually with the inner groove of adapter sleeve by supporting short circuit, so promptly solved the problem of easy deblocking, the deblocking shear pin is not stressed when packer set, reduced the installation quantity of deblocking shear pin simultaneously, made fishing easier, more convenient.
2, adopt trip gear, in the time of can not deblocking after packer is cut off the deblocking pin, have utilized trip gear, can carry out the unsealing operation of packer easily, carried out fishing easily, thereby improved operating speed, shortened duty cycle, reduced operating cost.
Four, description of drawings
