Laum YeebPuas yog cov yeeb nkab steel nrog xov kawg, uas yog siv los txuas cov khoom sib dhos rau cov khoom siv drilling thiab sib tsoo cov khoom siv hauv qab ntawm lub drilling. Laum cov yeeb nkab tuaj yeem muab faib ua peb pawg: Kelly, laum yeeb nkab thiab hnyav laum yeeb nkab.
Laum dab tshosNyob rau hauv qab ntawm txoj hlua laum thiab yog lub ntsiab tivthaiv ntawm cov sib dhos qis dua kev sib dhos. Nws lub ntsiab tseem ceeb yog tias lub phab ntsa tuab yog qhov loj dua, thiab nws muaj ntau lub zog nqus thiab nruj. Txhawm rau pab txhawb kev ua haujlwm, Of elevator grooves thiab swb grooves tuaj yeem ua tiav ntawm sab nraud ntawm cov xov sab hauv ntawm lub laum dab tshos. Laum collars feem ntau muab faib ua peb hom: Spiral Laum Collars, tsis- sib nqus tho laum dongars.
