Ib tug wireline laum pas nrig yog ib qho tshwj xeeb uas siv nyob rau hauv wireline core drilling, ib txoj kev uas feem ntau ua hauj lwm rau subsurface tshawb nrhiav thiab tau txais cov qauv zoo. Cov txheej txheem drilling no suav nrog kev siv cov kab hluav taws xob, qhov chaw laum pas nrig ua haujlwm rau kev khaws cov tub ntxhais txuas mus ntxiv los ntawm qhov borehole mus rau qhov chaw.
Cov yam ntxwv tseem ceeb thiab cov khoom xyaw:
Sab hauv Tube:
Lub raj sab hauv yog ib qho tseem ceeb ntawm cov hlua hlau laum pas nrig, tsim kom muaj thiab tiv thaiv cov tub ntxhais cov qauv thaum lub sij hawm drilling. Nws yog txawm peem rau nrog nta xws li ib tug tub ntxhais lifter rooj plaub nyob rau hauv qab kom ruaj ntseg cov tub ntxhais thaum lub sij hawm extraction.
Tube sab nraud:
Nyob ib puag ncig lub raj sab hauv yog lub raj sab nrauv, muab kev txhawb nqa rau kev sib dhos. Lub raj sab nraud tseem nyob hauv qhov borehole thaum lub raj sab hauv yog nqa mus rau saum npoo, tso cai rau kev ua haujlwm zoo thiab txuas mus ntxiv.
Threaded Connections:
Ob qhov kawg ntawm lub xov hlau laum pas nrig feem ntau muaj cov xov txuas txuas. Cov kev sib txuas no pab txhawb kev sib dhos thiab disassembly ntawm lub laum pas nrig thaum lub sijhawm ua haujlwm drilling.
Landing Ring:
Nyob ze rau sab saum toj ntawm lub raj sab hauv, lub nplhaib tsaws pab hauv kev taw qhia thiab qhov chaw nruab nrab ntawm cov tub ntxhais chim thaum lub sij hawm muab rov qab, kom ntseeg tau tias cov qauv tseem ceeb nyob twj ywm.
Wireline Core Drilling Txheej Txheem:
Drilling:
Lub wireline laum pas nrig, nruab nrog ib tug tseem ceeb me ntsis, yog qis rau hauv lub borehole. Cov tub ntxhais me ntsis txiav los ntawm subsurface, thiab cov qauv tseem ceeb nkag mus rau hauv lub raj sab hauv.
Rov qab:
Thaum drilling ua tiav ntawm qhov tob, lub raj sab hauv, uas muaj cov qauv tseem ceeb, tau nqa mus rau saum npoo siv lub tshuab xaim winch. Lub raj sab nraud tseem nyob hauv qhov borehole, tso cai rau kev drilling ceev thiab txuas ntxiv.
Core tuav:
Nyob rau saum npoo, cov qauv tseem ceeb yog muab rho tawm los ntawm lub raj sab hauv rau kev kuaj xyuas, ntsuas, thiab txiav.
Wireline core drilling yog paub txog nws qhov kev ua tau zoo hauv kev tau txais cov qauv zoo, tsis muaj kev cuam tshuam los ntawm qhov tob tob. Kev tsim ntawm cov hlua hlau laum pas nrig, nrog nws cov raj sab hauv thiab sab nraud thiab cov yam ntxwv tshwj xeeb, ua kom yooj yim rau kev rov qab ua kom zoo thiab txuas ntxiv ntawm cov qauv hauv cov txheej txheem drilling.
