Nws yog dav siv nyob rau hauv cov cementing tej yaam num los ua tus txheej txheem retainer rau phab ntsa ntawm cov roj thiab roj.
qhov dej los yog qhov dej zoo. Nws yog muab tso rau hauv ib tug zoo bore thiab cemented nyob rau hauv qhov chaw los tiv thaiv ob subsurface formations
thiab lub qhov dej los ntawm kev sib tsoo thiab tso cai rau cov dej drilling kom ntws thiab rho tawm los ua qhov chaw.
Lub ntsiab steel qib ntawm API 5CT: API 5CT J55, API 5CT K55, API 5CT N80, API 5CT L80, API 5CT P110. Qhov no
International Standard muaj feem xyuam rau cov kev sib txuas hauv qab no raws li ISO 10422 lossis API Spec 5B:
luv round xov casing (STC);
Ntev round xov casing (LC);
taub qab xov casing (BC);
kab mob siab heev (XC);
tubing tsis chim (NU);
sab nraud chim tubing (EU);
Integral Joint Tubing (IJ).
Rau cov kev sib txuas zoo li no, Cov Txheej Txheem Thoob Ntiaj Teb no qhia txog cov txheej txheem kev xa khoom rau kev sib txuas thiab
xov tiv thaiv. Rau cov kav dej los ntawm International Standard, qhov ntau thiab tsawg, pawg, phab ntsa thicknesses, qib
thiab siv qhov kawg tiav yog txhais. Qhov International Standard no kuj tseem siv tau rau cov tubular nrog kev sib txuas
tsis suav nrog ISO / API cov qauv.
