qhia txog cov khoom
:LEANOS
Ib tug xov tooj cua laum pas nrig yog ib hom ntawm cov khoom siv drilling siv nyob rau hauv cov tub ntxhais drilling kev ua haujlwm, feem ntau ua haujlwm hauv thaj chaw ntawm geology, mining, thiab kev tshawb nrhiav ib puag ncig. Lub sij hawm "wireline" yog hais txog cov txheej txheem ntawm kev muab cov qauv coj los siv ib qho tshwj xeeb cable lossis wireline system.
Kev kho cua sov
::LEANOSNtawm no yog cov yam ntxwv tseem ceeb thiab kev ua haujlwm ntawm wireline laum rods:
Core Retrieval System:
Wireline laum rods yog ib feem tseem ceeb ntawm lub wireline core drilling system. Cov txheej txheem no tso cai rau kev muab cov qauv coj mus kuaj yam tsis tas yuav rub tag nrho cov hlua tho tawm ntawm qhov borehole.
Hollow Inner Tube:
Lub laum pas nrig feem ntau muaj ib tug hollow puab raj. Qhov hollow seem no tso cai rau cov qauv tseem ceeb dhau los ntawm qhov nruab nrab ntawm lub laum pas nrig, txo qhov kev puas tsuaj rau tus qauv thaum lub sij hawm rho tawm.
Wireline Coring Method:
Wireline drilling yog siv los ntawm kev siv cov xov hlau (ib lub xov tooj nyias nyias los yog xaim) txuas rau lub raj sab hauv ntawm lub laum pas nrig. Lub taub hau tub ntxhais, uas tuav cov qauv ntawm cov tub ntxhais, txuas nrog cov kab hlau.
Ceev Core Retrieval:
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm wireline drilling yog lub peev xwm los khaws cov qauv ntsuas sai sai yam tsis tau tshem tawm tag nrho cov hlua tho los ntawm qhov borehole. Qhov kev ua tau zoo no yog qhov tseem ceeb rau kev txuag lub sijhawm thaum lub sijhawm ua haujlwm drilling.
Txo Downtime:
Txoj kev xaim coring minimizes downtime ntawm drilling khiav txij li lub laum txoj hlua tseem nyob rau hauv lub borehole. Qhov no tso cai rau kev ua haujlwm txuas ntxiv thiab ua haujlwm zoo dua.
Preservation ntawm Core Integrity:
Kev tsim cov kab laum kab hlau txuas pab khaws cia kev ncaj ncees ntawm cov qauv qauv. Txij li thaum lub raj sab hauv yog hollow, cov qauv tseem ceeb tuaj yeem muab rho tawm yam tsis muaj kev cuam tshuam lossis cuam tshuam, muab cov qauv zoo thiab tsis muaj kev cuam tshuam rau kev txheeb xyuas geological.
Suitability rau Deep Drilling:
Wireline drilling yog qhov tshwj xeeb zoo rau kev sib sib zog nqus drilling cov haujlwm uas cov qauv tseem ceeb yuav tsum tau sau los ntawm qhov tob tob. Qhov tseem ceeb retrieval system txhim khu kev tsim tau ntawm kev sib sib zog nqus drilling ua haujlwm.
Standardized Loj:
Wireline laum rods tuaj nyob rau hauv qhov ntau thiab tsawg, xws li B, N, H, thiab P, nrog rau txhua qhov loj sib xws rau ib txoj kab uas hla. Cov qauv no tso cai rau kev sib raug zoo nrog ntau yam khoom siv drilling thiab cov cuab yeej.
Compatibility nrog Core Barrels:
Lub wireline laum pas nrig yog tsim los ua haujlwm seamlessly nrog wireline core chim. Cov tub ntxhais chim yog txuas nrog lub wireline thiab tuaj yeem tsa tau yooj yim rau saum npoo, nqa cov qauv tub ntxhais nrog rau nws.
