API 5CT C90 Casing Tubing
Roj casing yog cov yeeb nkab steel siv los txhawb cov phab ntsa zoo ntawm cov roj thiab cov roj qhov dej kom ntseeg tau tias kev ua haujlwm zoo ntawm tag nrho cov roj zoo thaum lub sijhawm drilling thiab tom qab ua tiav.
Roj casing yog cov yeeb nkab loj-ntev uas ua lub luag haujlwm hauv kev kho cov phab ntsa los yog qhov dej ntawm cov roj thiab cov qhov dej zoo. Lub casing yog muab tso rau hauv lub qhov dej thiab tsau nrog cov cement los pab lub qhov dej sib cais cov pob zeb tsim thiab tiv thaiv lub qhov dej los ntawm kev sib tsoo, thaum ua kom cov dej ntws ntawm cov av nkos los pab txhawb kev drilling thiab mining. Hlau qib ntawm cov roj casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, thiab lwm yam. Casing kawg ua cov ntaub ntawv: luv round xov, ntev round xov, ib nrab trapezoidal xov, tshwj xeeb buckle, thiab lwm yam. Nws yog siv rau hauv cov roj zoo drilling los txhawb lub phab ntsa zoo thaum lub sij hawm drilling txheej txheem thiab tom qab ua tiav zoo los xyuas kom meej cov txheej txheem drilling thiab kev ua haujlwm zoo ntawm tag nrho cov roj zoo tom qab ua tiav.
