Casing Yeeb

Roj casing yog cov yeeb nkab steel siv los txhawb cov phab ntsa ntawm cov roj thiab cov roj av kom ntseeg tau tias kev ua haujlwm zoo ntawm cov txheej txheem drilling thiab tag nrho lub qhov dej tom qab ua tiav. Txhua lub qhov dej siv ob peb txheej ntawm casing nyob ntawm qhov tob drilling thiab geology. Casing tom qab lub qhov dej siv cov cement, nws txawv ntawm tubing, laum yeeb nkab, tsis tuaj yeem rov qab siv dua, belongs rau cov khoom siv ib zaug. Yog li, casing noj nyiaj ntau dua 70% ntawm tag nrho cov kav dej zoo.

 

Casing yuav muab faib ua yeeb nkab, nto casing, technical casing thiab roj casing raws li kev siv.

 

Daim ntawv thov:

 

Roj casing yog ib hom ntawm txoj kab uas hla loj, uas plays lub luag hauj lwm ntawm kho cov phab ntsa los yog lub qhov ntawm cov roj thiab cov roj. Casing yog muab tso rau hauv lub qhov dej thiab ruaj ntseg nrog cov cement los pab cais cov pob zeb tsim thiab tiv thaiv lub qhov los ntawm kev sib tsoo, thaum ua kom cov av nkos ntswj kom yooj yim drilling thiab ntau lawm.

 

Steel qib ntawm 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 trapezoid xov, tshwj xeeb buckle, thiab lwm yam. Nws yog tsuas yog siv los txhawb cov phab ntsa zoo thaum lub sijhawm drilling txheej txheem thiab tom qab ua tiav ntawm lub qhov dej, thiaj li ua kom lub cev ua haujlwm ntawm cov txheej txheem drilling thiab tag nrho lub qhov dej tom qab ua tiav.
