Description
Technical field:
The utility model belongs to the laminated distributor under well instrument of oil field oil recovery usefulness, relates to a kind of packer of bi-directional slip grappling.
Background technology:
Along with continually developing of oil field, how to develop the deep layer LOW PERMEABILITY RESERVOIR, improve oil recovery rate, be a great problem that the oil field faces.Owing to the reservoir geology complexity, bury reason such as dark, formation temperature height, it is high that the part well requires downhole tool, conventional packer effect is very undesirable, interior latus rectum is little, the restriction of latus rectum in some instrument and special tool etc. are subjected to can't be selected to use.Existing packer does not have tension force grappling function, easily causes flow string flexural deformation, and the oil well pump pump efficiency is reduced.
Summary of the invention:
At the deficiency that conventional packer in the past exists, the utility model provides a kind of bi-directional slip packer, and this packer bi-directional slip bidirectionally anchoring can be worked under pressurized, stretching and neutral three kinds of states.
The technical scheme that the utility model provides is:
The bi-directional slip packer comprises top connection, slips hanging sleeve, upper slips, cone, outer pipe connector sleeves, packing element, outer tube, inner central tube, suspension body cover, suspension body, lower contact, sheet spring, centralizer body, brake pad, bypass valve and lower slips; Connect inner central tube below the top connection, connect suspension body below the inner central tube, connect lower contact below the suspension body;
The inner central tube outer wall is socket slips hanging sleeve, upper slips, cone, bypass valve, outer pipe connector sleeves, outer tube successively from top to bottom; Outer tube outer wall is socket packing element, cone, lower slips, centralizer body successively from top to bottom; Centralizer body is provided with brake pad, is provided with the sheet spring between brake pad and the centralizer body, and the centralizer body lower end connects the suspension body cover.
Be provided with spring in the slips hanging sleeve.
The commutation pin is arranged on the suspension body.
Be provided with one in the upper slips and discharge slips.
Inner central tube top external diameter is greater than lower outer diameter.
The beneficial effects of the utility model are:
1, owing to be designed to the external track, latus rectum increases in the described bi-directional slip packer, makes the scope of application of instrument, instrument of packer more extensive.
2, described bi-directional slip packer adopts the bi-directional slip bidirectionally anchoring, and the duty grappling is reliable, no matter is to be in pressurized, tension or intermediateness, its mechanical anchor can both guarantee this packer bear from above or below pressure.After this packer grappling, on mechanical pumpingh well, use, can effectively overcome oil pipe and wriggle up and down, reduce the pump efficiency loss, improve mechanical oil recovery efficient.
3, process using such as described bi-directional slip packer setting, deblocking rotation tubing strings, press down or on put forward movable mode of operation, simple to operate, set, the deblocking flexibility and reliability.
4, increased the auxiliary sealing mechanism of separating,, be convenient to the packer deblocking as discharging slips etc.; Bypass valve can balance pressure reduction up and down, improve the deblocking safety.

Specific embodiment
The bi-directional slip packer is connected in the middle of the tubing string, and the commutation pin is in the orbital groove when going into the well, and promotes the bi-directional slip packer and moves down.The bi-directional slip packer with oil pipe down to projected depth, upper lifting pipe post suitable height, the commutation pin arrives the summit of track.The tubing string that turns clockwise makes the bi-directional slip packer turn over 1/4 circle, makes the commutation pin enter long track.
Slowly transfer tubing string then, this moment suspension body cover, brake pad, centralizer body and slips transfixion under the wall friction drag effect, the commutation pin is descending along long track, cone struts lower slips and sets up fulcrum at the borehole wall.Continue to transfer tubing string, under the effect of tubing string, top connection promotes upper slips with the slips hanging sleeve and contacts with cone, then promote cone, outer tube is descending, packing element is compressed Seal Oil cover annular space gradually, upper and lower slips is strutted by cone and is stuck on the casing wall, and the bi-directional slip packer enters the duty of bidirectionally anchoring.Simultaneously, when inner central tube moves down, when bypass valve arrives the big slightly top of inner central tube diameter, begin to enter sealing state in outer tube, the fluid passage between inner central tube and the outer tube is closed, and finishes to set operation.
During deblocking, upper lifting pipe post at first, make the bi-directional slip packer be in the middle chalaza of tubing string, the tubing string that turns clockwise makes the commutation pin rotate 45 ° and enters long track, the upper lifting pipe post, the centralizer body of bi-directional slip packer, brake pad and the last relative sleeve pipe of lower slips are static, and the commutation pin is opened bypass valve along moving on the long track, treat on the bi-directional slip packer after the pressure balance, carry in the continuation, discharge slips and under the effect of slips hanging sleeve, regain gradually, afterwards upper slips, lower slips is pulled in succession, break away from cone, anchorage force disappears, and packing element recovers under resilient force, finishes deblocking technology.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
