Description
Technical field
The present invention relates to the field produces well logging field, particularly rod tube is carried the anti-top of the tappet that adopts and tripper and on-the-spot using method in the Production Logging in Horizontal Wells process.
Background technology
At present, in the horizontal well test technology, need to adopt a kind of anti-ejection device, can make tubing string promote the tappet post, the power of horizontal feed is provided, tester is transported to the precalculated position; Simultaneously, can also carry out release after instrument arrives test position, tester can abovely be carried, finish follow-on test, this device is the critical component that determines the horizontal wellbore logging success or failure.
Chinese patent notification number CN2083190 provides a kind of " underground blowout preventer ".Mainly by lower contact, garter spring, friction plate, central tube, cone, deter pin, outer tube, top connection and form, in lower contact friction plate is housed, also have the blanking plug that can be connected with the top connection endoporus.It can be used for operation in the not kill-job of water filling, shuts the formation water ground of scurrying out, when lift pipe string, as long as drop into blanking plug from well head, just can satisfy the not operation technique requirement of open flow of not kill-job, and can automatically prevent borehole pressure to the upper top power of tubing string, oil pipe is altered on unlikely.Should prevent apical organ owing to need to drop into blanking plug, can't satisfy removing of tester, can not satisfy the horizontal wellbore logging needs.
Chinese patent notification number CN101173600 provides a kind of " anti-prop slips capable of dragging ".The descending promotion slips of cone outwards opens and is anchored on the sleeve pipe, and after cone was descending, cone lost the constraint to lock dog, and upper body and lower body are thrown off.Owing to be that the grappling of finishing with pump is thrown off, therefore, upper body and lower body being thrown off salvage pipe just can lower sucker rod production after upwards extracting out, do not need to beat prevent the tubing string that pushes up all trip out after down with the flow string of pump.When needing the downhole tool of maintenance bottom, do not need flow string is all proposed to descend fishing string again, only need again flow string to be transferred, lock dog stops that no longer the salvaging pipe is descending, after making it salvage the pipe lower thread and the cone internal whorl contacts, the swivelling pipe male screw screws, and screws rear upper lifting pipe post, to carry on the cone, slips is just regained from casing wall, continues the upper lifting pipe post, whole downhole tools can be proposed, reduce flow chart, reduce the activity duration.This anti-jack slips is applicable to use at inside pipe casing, in case behind the anti-top, tubing string can not move upward; And size is larger, can't satisfy the tappet post is carried tester in the down-hole horizontal section needs.
Chinese patent notification number CN201448073U provides a kind of " self-fishing up-running preventing slip ".The separating joint bottom is milled and is split into the bar body, evagination shoulder on the bar body is suspended on shoulder place in the suspension joint bottom, suspension joint is connected with housing, cone is installed in the housing, and slips is installed at the window place of housing, and the propeller bottom is installed in the cone, propeller pins the separating joint bottom, each the bar body that the separating joint bottom is milled be split into can not inwardly shrink, and pull bar top is connected with propeller, and the pull bar bottom is provided with boss.The external diameter of boss is greater than the internal diameter of top cover.Packer set needed axial force in its underpart is fixed by slips, realizes producing after separating joint and suspension joint are thrown off, and upper lifting pipe post in the time of need to pulling out, the set boss in pull bar bottom can with upwards pulling of cone, regain lower packer deblocking and slips.Throw off and pull out and do not need other lower tubular column.This anti-jack slips needs the upper lifting pipe post when release, it is motionless and the purpose of only separating the locking tappet post can't satisfy the horizontal wellbore logging requirement to reach tubing string.
