IADC 637 (Code X) TCI phau ntawv xov xwm kaw lub cev tricone ntsis, nruab nrog kev tiv thaiv gauge, yog tsim tshwj xeeb rau cov qauv nyuaj nrog lub zog compressive siab xws li 100-150 MPa (14,500-23,000 PSI) - qhov zoo tseem ceeb cuam tshuam hauv cov lus tawm tswv yim kawg ntawm cov neeg siv khoom. Nrog rau qhov loj me ntawm 9 5/8 "txog 9 7/8", nws siv cov khoom siv tungsten los hloov kho rau cov kev xav tau ntawm cov av nkos hauv kev khawb dej zoo, thiab phim nrog 3-sab dav hlau ib txwm muaj. Cov neeg siv khoom tshaj tawm nws qhov kev tiv thaiv zoo heev thiab kev ncig av nkos ruaj khov, ua rau kev ua haujlwm zoo hauv cov qauv nyuaj. Lub caij no, kev tsim qauv tiv thaiv kev kaw thiab gauge txuas ntxiv nws lub neej kev pabcuam, txhim kho kev ua haujlwm drilling tag nrho thiab kev siv nyiaj tsawg.
kev ua ub ua no.
