Lub taub hau API drilling IADC117 4 5/8 nti (117.5 hli) rau rig
Kev piav qhia txog khoom
Hauv cov txheej txheem drilling, lub laum ntsis yog lub cuab yeej tseem ceeb los tsoo pob zeb thiab lub qhov dej yog tsim los ntawm lub laum ntsis tsoo pob zeb. Lub qhov dej zoo li cas thiab lub sijhawm ntev npaum li cas tsis yog tsuas yog cuam tshuam nrog cov yam ntxwv ntawm pob zeb hauv qhov chaw drilling thiab kev ua haujlwm ntawm lub laum ntsis nws tus kheej xwb, tab sis kuj tseem cuam tshuam rau qib kev sib phim ntawm lub laum ntsis thiab qhov chaw tsim. Kev xaiv cov laum ntsis tsim nyog ua lub luag haujlwm tseem ceeb hauv kev nce qhov ceev drilling thiab txo cov nqi tag nrho ntawm kev drilling.
Lub laum yog ib qho ntawm cov cuab yeej tseem ceeb rau kev ua haujlwm drilling roj. Seb lub laum hloov kho rau cov yam ntxwv ntawm pob zeb thiab nws qhov zoo ua lub luag haujlwm tseem ceeb heev hauv kev xaiv cov thev naus laus zis drilling, tshwj xeeb tshaj yog hais txog qhov zoo ntawm drilling, qhov ceev ntawm drilling thiab tus nqi drilling.
