Description
Technical field
The present invention relates to field produces well logging field, particularly in Production Logging in Horizontal Wells process, rod tube carries the anti-top of tappet and tripper and on-the-spot using method that adopt.
Background technology
At present, in horizontal well test technology, need to adopt a kind of anti-ejection device, tubing string can be made to promote tappet post, the power of horizontal feed is provided, tester is transported to precalculated position; , can also unlock after instrument arrives test position meanwhile, tester can be carried above, complete follow-on test, this device is the critical component determining horizontal wellbore logging success or failure.
Chinese patent notification number CN2083190, provides one " underground blowout preventer ".Primarily of lower contact, garter spring, friction plate, central tube, cone, deter pin, outer tube, top connection composition, friction plate is equipped with in lower contact, also has a blanking plug that can be connected with top connection endoporus.It can be used for operation on water filling no killing well, shuts formation water and to scurry out ground, when lift pipe string, as long as drop into blanking plug from well head, just can meet the operation technique requirement of no killing well not open flow, and can automatically prevent borehole pressure to the upper top power of tubing string, make oil pipe unlikely on alter.This anti-apical organ drops into blanking plug due to needs, cannot meet removing of tester, can not meet horizontal wellbore logging needs.
Chinese patent notification number CN101173600, provides one " anti-prop slips capable of dragging ".The descending promotion slips of cone outwards opens and is anchored on sleeve pipe, and after cone is descending, cone loses the constraint to lock dog, and upper body and lower body are thrown off.Owing to being that the grappling that completes of band pump is thrown off, therefore, just can lower sucker rod production after upper body and lower body being thrown off salvage pipe upwards to be extracted out, do not need the flow string playing band pump after all being tripped out by the tubing string beating anti-top again.When needing the downhole tool overhauling bottom, do not need flow string all to be proposed descend fishing string again, only need again flow string to be transferred, lock dog no longer stops that salvaging pipe is descending, make it salvage after pipe lower thread contacts with cone internal whorl, swivelling pipe male screw screws, and screws rear upper lifting pipe post, carry in cone, slips is just regained from casing wall, continues upper lifting pipe post, whole downhole tool can be proposed, reduce flow chart, reduce the activity duration.This anti-jack slips is applicable in inside pipe casing application, once behind anti-top, tubing string can not move upward; And size is comparatively large, the needs of tappet post at down-hole horizontal section conveying tester cannot be met.
Chinese patent notification number CN201448073U, provides one " self-fishing up-running preventing slip ".The milling of separating joint bottom is split into bar body, evagination shoulder on bar body is suspended on shoulder place in suspension joint bottom, suspension joint is connected with housing, install cone in housing, slips is installed at the window place of housing, and propeller bottom is arranged in cone, propeller pins separating joint bottom, each bar body that the milling of separating joint bottom is split into can not inwardly shrink, and pull bar top is connected with propeller, and pull bar bottom is provided with boss.The external diameter of boss is greater than the internal diameter of top cover.Axial force required for the packer set of its underpart is fixed by slips, realizes producing after separating joint and suspension joint are thrown off, upper lifting pipe post when needing to pull out, and set by pull bar bottom, cone can upwards pull by boss, makes lower packer deblocking and slips withdrawal.Throw off and pull out and do not need another lower tubular column.This anti-jack slips needs upper lifting pipe post when unlocking, and cannot reach tubing string motionless and only separate the object of locking tappet post, cannot meet horizontal wellbore logging requirement.
