Casing yog txoj kab uas hla loj uas tau sib sau ua ke thiab muab tso rau hauv ib qho tsis ntev los no drilled seem ntawm ib lub borehole thiab feem ntau
tuav rau hauv qhov chaw nrog cement. Thiab peb muab ntau yam Seamless Casing los ntawm 4-1/2 ''-20'' nyob rau hauv qib H40, J55, K55,
N80, L80, C95, P110 thiab lwm yam Casing ntev yog R1, R2, R3, nrog threads ntawm BTC, LTC, STC. Raws li lub zog
ntawm steel casing tuaj yeem muab faib ua qib steel sib txawv, sib sib zog nqus zoo, siv qib steel sib txawv. Nyob rau hauv ib puag ncig corrosive
kuj yuav tsum tau lub casing nws tus kheej muaj corrosion kuj. Nyob rau hauv qhov nyuaj geological mob qhov chaw kuj nug lub casing
muaj kev tiv thaiv kev sib tsoo.
