Ib qho Rov Qab Rov Qab Drilling Rauj yog cov cuab yeej tshwj xeeb drilling uas siv rau hauv kev rov qab ua haujlwm drilling. Nyob rau hauv rov qab ncig drilling, cov dej drilling thiab txiav yog coj mus rau saum npoo los ntawm ib lub raj sab hauv, uas tso cai rau kom muaj txiaj ntsig zoo thiab cov qauv zoo los ntawm cov khoom siv subsurface.
Kev ua haujlwm
LEANOS
Rov qab Circulation Drilling Rauj txuas nrog RC (Rov Rov Los Circulation) Laum Pipe siv txoj kev sib txuas tshwj xeeb los pab txhawb cov dej ntws zoo ntawm cov dej drilling thiab txiav hauv qhov rov qab ncig drilling. Ntawm no yog li cas kev sib txuas ntawm rauj thiab RC laum yeeb nkab feem ntau ua haujlwm:
Hammer Sub: Rov qab Circulation Drilling Rauj muaj threaded sub los yog txuas taw tes ntawm nws sab sauv kawg. Cov sub no yog tsim los txuas rau qis kawg ntawm RC laum yeeb nkab.
RC Drill Pipe: Lub RC laum yeeb nkab kuj muaj cov xov sib txuas ntawm nws qhov qis kawg, hu ua "rauj sub" lossis "rauj sib koom ua ke." Qhov kev sib txuas no yog tsim tshwj xeeb kom phim rau rauj lub sub.
Threaded kev twb kev txuas: Ua kom muaj kev sib txuas, threaded sub ntawm Reverse Circulation Drilling Hammer yog screwed mus rau threaded kev twb kev txuas ntawm RC laum yeeb nkab. Qhov no tsim kom muaj kev ruaj ntseg thiab kaw kev sib txuas ntawm ob yam khoom.
Sealing thiab Xauv: Txhawm rau kom muaj kev sib khi kom raug thiab tiv thaiv kom tsis txhob xau, cov khoom sib khi, xws li O-ring lossis foob, yuav raug siv nyob rau hauv cov xov txuas. Qhov no yuav pab tswj kom muaj kev ncaj ncees ntawm cov dej drilling.
Torqueing: Kev ua kom zoo torqueing lossis nruj ntawm qhov kev sib txuas yog qhov tseem ceeb los tswj kev ncaj ncees ntawm kev sib txuas thiab tiv thaiv kev sib cais thaum lub sijhawm ua haujlwm drilling. Lub torque ciaj ntswj lossis cov cuab yeej zoo sib xws yuav raug siv los ua kom tau raws li qhov pom zoo torque qhov tseem ceeb teev los ntawm cov chaw tsim khoom.
Kev tshuaj xyuas: Ua ntej kev ua haujlwm drilling pib, nws yog ib qho tseem ceeb uas yuav tsum tau soj ntsuam qhov kev sib txuas kom ntseeg tau tias nws raug kaw kom zoo, kaw, thiab tsis muaj qhov tsis xws luag uas tuaj yeem cuam tshuam cov dej ntws ntawm drilling.
