Nyob rau hauv cov roj thiab roj drilling, txoj hlua laum yog ib qho kev sib dhos tseem ceeb ua kom muaj lub hom phiaj tshwj xeeb (HDI) txhua qhov muaj kev nyab xeeb, txhim khu kev qha, thiab siv tau zoo.
API Kev faib tawm (spec 5Dp & spec 7-1)
API muab cov qauv tshwj xeeb kom ntseeg tau qhov zoo thiab ua tau zoo ntawm cov hlua laum cov khoom siv:
