Abstract
The utility model provides a hydraulic packer sealing set separation mechanism. Large thread at the bottom of an upper joint is joined with a sealing cylinder. Small thread at the bottom of the upper joint is joined with the top of a back-off pipe. A plunger is arranged between the sealing cylinder and the back-off pipe. A fishing joint is arranged in the bottom of the plunger. Top of the fishing joint is provided with internal thread. The inner tube is arranged in the internal thread on top of the fishing joint. The lower part of the back-off pipe is milled into strip shape, and is provided with thread which is joined with the internal thread on the top of the inner tube. A sliding bush is fixed in the back-off pipe with pins. A valve ball is arranged on the sliding bush. When the utility model is used, hydraulic pressure is injected into the utility model; the plunger moves down so that the packer anchors the sealing set, and then pins are cut off; the sliding bush goes down; the back-off pipe is unrestricted. As the lower part of the back-off pipe is milled into strip shape, the lower part can get away from the internal thread of the inner tube to achieve separation. Accordingly the utility model can be operated easily and simply, and separates reliably.
Description
One, technical field
The utility model is the laminated distributor under well oil tool of oil field oil recovery usefulness, particularly a kind of hydraulic packer seat sealed separating mechanism.
Two, background technology
Implement layering card water blockoff oil recovery technique, envelope is fallen high aquifer, is the effective way that the control well water rises.Layering card water blockoff will adopt packer, existing packer kind is more, wherein one type packer is to suppress the seat envelope after bringing it into the oil reservoir position by oil pipe, and then oil pipe separated with packer, realize that this process scene is called and give up, the packer that is adopted is the Y445 hydraulic packer, has comprised a kind of separating mechanism in this packer, and present separating mechanism has multiple structure, but all there is certain defective, have plenty of inconvenient operation, operation is many, finishes that to separate the used time long, it is not high to have plenty of reliability, can not separate, also have plenty of and cause in the separation process of carrying out that anchor mechanism lost efficacy, and caused packer blow-by in well.
Three, summary of the invention
The purpose of this utility model is a kind of hydraulic packer seat sealed separating mechanism of design, makes it easy and simple to handle, reliable separation.
The purpose of this utility model is achieved in that by top connection, sealing drum, piston, fishing joint, interior pipe to be formed.Top connection bottom major thread connects with sealing drum, top connection bottom minor thread connects with the pipe top of giving up, piston is in sealing drum and gives up between the pipe, fishing joint is in the piston bottom, internal thread is arranged at fishing joint top, in interior pipe is under the fishing joint upper internal threaded, the pipe bottom of giving up is milled and is split into the bar body, give up the pipe bottom screw thread is arranged, this screw thread connects with interior pipe upper internal threaded, give up the pipe bottom mill be split into the bar body root on the screw thread of its underpart, sliding sleeve is placed in the pipe of giving up, and sliding sleeve bottom outer wall mills the inwall that is split into the bar body with the pipe bottom of giving up and contacts, and its pipe bottom internal diameter of giving up can not be dwindled, in the pipe of giving up, valve ball is located on the sliding sleeve sliding sleeve by dowel fixes.
The beneficial effects of the utility model are: when the utility model injects hydraulic pressure to its inside, piston moves down and makes packer anchor block envelope, cuts off pin then, and sliding sleeve is descending, lose constraint to the pipe of giving up, the pipe bottom of giving up is milled and is split into the bar body, can deviate from the internal thread of interior pipe, realizes separating, therefore, the utility model can reach purpose of design, and is easy and simple to handle, reliable separation.
Four, description of drawings
Accompanying drawing is the structure assembling drawing of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Form by top connection 1, sealing drum 2, piston 3, the pipe 4 of giving up, valve ball 5, pin 6, fishing joint 7, sliding sleeve 8, interior pipe 9.Top connection 1 bottom major thread connects with sealing drum 2, top connection 1 bottom minor thread connects with pipe 4 tops of giving up, piston 3 is in sealing drum 2 and gives up between the pipe 4, fishing joint 7 is in piston 3 bottoms, internal thread is arranged at fishing joint 7 tops, in interior pipe 9 is under fishing joint 7 upper internal threaded, pipe 4 bottoms of giving up are milled and are split into the bar body, give up the pipe 4 bottoms screw thread is arranged, this screw thread connects with interior pipe 9 upper internal threaded, give up the pipe 4 bottoms mill be split into the bar body root on the screw thread of its underpart, sliding sleeve 8 is placed in the pipe 4 of giving up, and sliding sleeve 8 bottom outer walls mill the inwall that is split into the bar body with pipe 4 bottoms of giving up and contact, and its pipe 4 bottom internal diameters of giving up can not be dwindled, sliding sleeve 8 is fixed in the pipe 4 of giving up by pin 6, and valve ball 5 is located on the sliding sleeve 8.Giving up, to connect screw thread with interior pipe 9 tops be left hand thread in pipe 4 bottoms.Give up to manage under the 4 top screw threads linked hole is arranged.
During use, to its inner hydraulic pressure that injects, piston 3 moves down and makes packer anchor block envelope, cut off pin 6 then, sliding sleeve 8 is descending, loses the constraint to the pipe 4 of giving up, pipe 4 bottoms are milled and are split into the bar body because give up, and can deviate from the internal thread of interior pipe 9, realize separating.
