Abstract
The utility model relates to a hydraulic collision pressure type well completion pipe string suspension packer used for petroleum drilling engineering, which is composed of an upper rubber plug 1, an upper joint 2, a circlip sleeve 3, a rubber cylinder 5, a delivering pipe 6, a conical body 7, a slip 8, a base pipe 9, a sealing ring 11, a sealing sleeve 12, a big buckle changing joint 13, a piston 14, a locking block 15, a releasing seat 17, a liquid cylinder 18, a hollow rubber plug 20, a ball seat 23, a ball seat pin 22, a rubber plug pin 19, a releasing pin 16, a hanging pin 10 and a shearing pin 4. The packer adopts the hydraulic suspension and hydraulic release, which ensures that a well completion pipe post can be swimmingly delivered to a designed position; the reliable suspension and release can be ensured; the operation for cementing and well cementing can be carried out after releasing; the annular hollow pack can be carried out after well cementing; the affection of well cementing quality caused by the excess sinking of grout can be avoided.
Description
Technical field: the utility model relates to a kind of downhole hardware that is used for petroleum drilling engineering.
Prior art: all require completion tubular column down to design attitude when completion in advance in the oil drilling and the construction of the sidetracked hole in the well workover, and the precalculated position in the sleeve pipe of upper strata hangs, gives up, again according to the well-completing process needs, whether decision carries out the cementing well operation at last.The completion tubular column that uses in the prior art generally adopts mechanical type, waterpower formula or waterpower one mechanical type suspension arrangement.Above-mentioned these device ubiquities complicated operation, the problem of misoperation, hang, give up safety such as not having obviously demonstration and reliability aspect occurred easily.And can only hang tubing string, can not the packing annular space.
The purpose of this utility model is to provide a kind of can be guaranteed to hang, give up reliably, and can carry out the hydraulic pressure bruising formula completion tubular column suspension packing device of excluder ring idle job behind cementing well.
Technical scheme: the utility model is to realize like this.This device by top cement plug, top connection, jump ring cover, rubber tube, send into pipe, cone, slips, parent tube, joint ring, sealing shroud, greatly become snapping head, piston, lock dog, the seat of giving up, fluid cylinder, hollow plug, ball seat, ball seat pin, plug pin, the pin of giving up, hang pin, shear pin is formed.The suspension of this device and the operating process of giving up are pressurizeed by the ground turn on pump and are finished.When hanging and give up, two processes of two differential differentiations of bigger pressure are adopted in segmentation, and can adopt the suspending weight method further to verify to hang and give up.Can select cementing well after giving up or the two kinds of completion methods of not cementing the well.When selecting cementing well, be pressed into top cement plug with cement paste, be pressed in the hollow plug, the descending therewith cement paste that replaces out in the completion tubular column, and with the ball seat bruising, guarantee not stay the superfluous water bod in the tail pipe.Send into tubing string by pressing down after solid water mud is finished, make the packing device action that is positioned at the device upper end realize the annular space packing.If do not need the cementing completion, as long as hollow plug is proposed with sending into pipe.
The utility model can guarantee completion tubular column smoothly down to design attitude, and it is reliable to guarantee to hang, give up.This device adopts hydraulic suspension, and hydraulic pressure is given up, and not only can carry out the cementing well operation after giving up, and can carry out the annular space packing after well cementation, prevents that cement paste from sinking to too much influencing cementing quality.
Description of drawings: accompanying drawing is the utility model general structure schematic diagram.
The specific embodiment: as shown in the figure, the utility model is by top cement plug 1, top connection 2, jump ring cover 3, shear pin 4, rubber tube 5, send into pipe 6, cone 7, slips 8, parent tube 9, hang pin 10, joint ring 11, sealing shroud 12, the big snapping head 13 that becomes, piston 14, lock dog 15, the pin 16 of giving up, give up the seat 17, fluid cylinder 18, plug pin 19, hollow plug 20, ball seat piston 21, ball seat pin 22 and ball seat 23 are formed, its structure, assembled relation is as follows: the top of device is top connection 2, its lower end with send into pipe and 6 link to each other, be ball seat 23 bottom, ball seat 23 is contained in completion tubular column bottom, links to each other with the seat 17 of giving up of its top by completion tubular column; Top connection 2 belows are connected fluid cylinder 18 by sending into pipe 6 with the big snapping head 13 that becomes, and are fixing hollow plug 20 with plug pin 19 on the fluid cylinder 18, and are linking to each other with the seat 17 of giving up by lock dog 15; The seat of giving up connects parent tube 9 on 17, and sealing shroud 12, joint ring 11, slips 8, cone 7, rubber tube 5 and jump ring cover 3 are installed on the parent tube 9.This device with under the drilling tool behind design attitude, steel ball is dropped into by sending in the pipe 6, seat is on ball seat piston 21; After turn on pump is sprained and pressed, under hydraulic action, cut off and hang pin 10, joint ring 11 up promotion slips 8 actions realize the suspension of completion tubular column; After completion tubular column hangs, continue to improve pump pressure, cut off the pin 16 of giving up, piston 14 is descending, and lock dog 15 skids off, and tubing string is sent in realization and the completion tubular column disengagement is given up; Continue pressurization, cut off ball seat pin 22, ball seat piston 21 is descending, recovers circulation canal.If when needing cementing well, can then inject cement and top cement plug 1; During for mud, top cement plug 1 arrives in the hollow plug 20 together descending, comes downwards to ball seat 23 places bruising, and the cement paste in the completion tubular column is all replaced into annular space, finishes well cementing operation.Press down and send into tubing string, cut off shear pin 4, it is 3 descending that jump ring overlaps, and rubber tube 5 expands and realizes the seat envelope.
