Nyob rau hauv lub complex ntiaj teb no ntawm cov roj thiab roj zoo tsim, lublub taub hau plays lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ncaj ncees, kev nyab xeeb, thiab kev ua haujlwm zoo. Raws li lub hauv paus tseem ceeb ntawm kev sib sau ua ke ntawm lub qhov dej, nws ua haujlwm rau ntau yam tseem ceeb hauv lub neej ntawm lub qhov dej.
① Lub hauv paus ntawm Wellhead System
Covlub taub hautsim lub hauv paus ntawm lub taub hau sib dhos, feem ntau ntsia rau saum npoo casing. Nws lub zog tsim thiab kev tsim kho ua rau nws yog lub hauv paus pob zeb uas tag nrho lub qhov dej tau tsim. Lub luag haujlwm tseem ceeb no yog qhov tseem ceeb rau kev tswj xyuas kom zoo thiab kev ncaj ncees thoob plaws hauv qhov drilling, ua tiav, thiab cov theem tsim khoom.
② Kev them nyiaj yug thiab qhov hnyav faib
Ib lub hom phiaj tseem ceeb ntawm covlub taub hauyog los txhawb qhov hnyav ntawm cov hlua casing tom ntej. Nws yog tsim los dais ntau yam loads, zoo faib lub luj ntawm puab casing hlua thiab cov khoom txuam. Lub peev xwm ntawm cov kabmob no yog qhov tseem ceeb rau kev tswj xyuas qhov zoo ntawm qhov chaw ruaj khov thiab tiv thaiv kev sib tsoo lossis tsis ua haujlwm.
③ Kev Ruaj Ntseg
Lawv raug tsim los tiv thaiv kev kub ntxhov uas tau ntsib thaum lub sijhawm ua haujlwm drilling thiab ntau lawm. Lawv ua hauj lwm ua thawj kab ntawm kev tiv thaiv tawm tsam muaj peev xwm blowouts los ntawm kev muaj lub siab zoo. nws qhov kev ntsuas siab feem ntau yog xaiv raws li qhov xav tau siab tshaj plaws ntawm lub siab zoo, ua kom muaj kev nyab xeeb thiab tswj tau zoo nyob rau hauv ntau yam kev ua haujlwm.
④Casing String Suspension
Covlub taub haumuab ib tug txhais tau tias tshem tawm thiab kaw ntau cov hlua casing. Nws suav nrog casing hangers uas txhawb nqa qhov hnyav ntawm cov hlua khi sab hauv thaum tuav lub siab nruj ntawm cov hlua casing thiab lub taub hau. Qhov kev ncua kev kawm no yog qhov tseem ceeb rau kev tsim kho kom zoo thiab kev sib cais zonal.
⑤Txoj kev nkag thiab tswj
Lwm lub hom phiaj tseem ceeb yog muab kev nkag mus rau casing annuli. Nws nta sab qhov hluav taws xob uas tso cai rau:
ib. Kev soj ntsuam ntawm annular pressures
b. Kev khiav dej num rau kev tswj kom zoo
c. Txhaj cov cement lossis lwm yam khoom siv rau kev kho mob
d. Installation ntawm li qub rau annular siab tswj
Qhov kev nkag mus rau annular no yog qhov tseem ceeb rau kev tswj xyuas kom zoo thiab ua ntau yam kev cuam tshuam zoo thoob plaws hauv lub neej ntawm qhov dej.
⑥ Blowout Preventer (BOP) Kev teeb tsa
Thaum lub sijhawm ua haujlwm drilling, lublub taub hauua hauj lwm raws li lub mounting point rau lub blowout inhibiter pawg. Nws cov qauv tsim muaj zog thiab kev ntsuas siab ua rau nws tsim nyog rau kev txhawb nqa qhov hnyav ntawm BOP cov cuab yeej thaum tuav lub foob kaw ntom ntom. Qhov kev muaj peev xwm no yog qhov tseem ceeb rau kev tswj xyuas kom zoo thaum lub sijhawm ua haujlwm drilling thiab ua haujlwm ua haujlwm.
