Cov yeeb nkab laum yog tsim los ntawm kev sib txuas ntawm yam tsawg kawg peb qhov sib cais: lub thawv cuab yeej sib koom, tus pin cuab yeej sib txuas, thiab lub raj.Qhov kawg ntawm cov hlab ntsha yog ces chim siab kom nce qhov chaw hla ntawm qhov kawg.Lub raj kawg tuaj yeem ntxhov siab sab nraud (EU), kev chim siab sab hauv (IU), lossis sab hauv thiab sab nraud chim siab (IEU).Tus qauv max chim siab qhov ntev yog teev nyob rau hauv API 5DP, tab sis qhov tseeb qhov ntev ntawm qhov chim siab yog tus tswv rau cov chaw tsim khoom.Tom qab ntxhov siab, lub raj xa mus los ntawm kev kho cua sov.Drill yeeb nkab steel feem ntau quenched thiab tempered kom ua tau siab yield zog
Drilling yeeb nkab yog ib hom steel tubes nrog threaded tail, feem ntau yog siv los txuas cov cuab yeej nto ntawm drilling rig thiab drilling thiab sib tsoo cov cuab yeej lossis cov cuab yeej hauv qab ntawm qhov drilling.Lub hom phiaj ntawm cov yeeb nkab laum yog thauj cov av nkos mus rau qhov me me thiab nce, qis lossis tig lub qhov hauv qab lub cuab yeej ua ke nrog me ntsis.Lub laum yeeb nkab yuav tsum muaj peev xwm tiv taus lub siab loj sab hauv thiab sab nraud, twist, khoov thiab vibration.Nyob rau hauv cov txheej txheem ntawm cov roj thiab roj extraction, laum yeeb nkab yuav siv tau ntau zaus.Laum yeeb nkab tuaj yeem muab faib ua peb hom: Kelly, laum yeeb nkab thiab qhov hnyav laum yeeb nkab
