OCTGsawv rauRoj Lub Tebchaws Tubular Khoom. Cov no yog tsev neeg ntawm seamless thiab welded dov- steel khoom siv tshwj xeeb hauv kev drilling, ua tiav, thiab tsim cov roj thiab cov qhov dej.
Casing (Cov phab ntsa tsim qauv)
Casing yog ib tug loj - txoj kab uas hla cov yeeb nkab uas tau muab tso rau hauv ib tug tshiab drilled borehole thiab cemented rau hauv qhov chaw. Nws ua raws li cov txheej txheem retainer rau cov phab ntsa ntawm lub qhov dej.
Lub hom phiaj:Txhawm rau tiv thaiv lub qhov dej los ntawm kev sib tsoo, tiv thaiv cov dej hauv av los ntawm kev sib kis, thiab muaj - thaj chaw siab.
Sub-Types (raws li theem kev teeb tsa):
Conductor Casing:Thawj txoj hlua; tiv thaiv sab saum toj ntawm qhov dej los ntawm caving.
Nto Casing:Tiv thaiv cov dej tsis qab ntsev thiab txhawb nqa lub tshuab hluav taws xob tiv thaiv (BOP).
Intermediate Casing:Siv nyob rau hauv qhov tob tob kom cais cov siab - siab los yog cov pob zeb tsis ruaj khov.
Production Casing:Txoj hlua kawg uas khiav mus rau lub pas dej; cais thaj chaw tsim khoom.
Liner:Zoo ib yam li cov casing ntau lawm tab sis tsis khiav rov qab mus rau saum npoo; nws "hangs" los ntawm yav dhau los casing hlua kom txuag tau nqi.
OCTG Tubing Parameter Table
Tubing yog siv los thauj cov roj lossis roj los ntawm cov dej hauv qab mus rau qhov chaw.

Tubing (Cov kav dej ntau lawm)
Tubing yog cov yeeb nkab uas cov roj los yog roj tau thauj los ntawm cov dej hauv av mus rau qhov chaw. Nws tau muab tso rau hauv qhov tsim cov casing.
Lub hom phiaj:Los ua ib qho kev hloov pauv tau rau cov roj thiab roj. Tsis zoo li casing, tubing tsis yog cemented nyob rau hauv qhov chaw thiab tuaj yeem raug tshem tawm los kho lossis hloov yog tias nws corrodes los yog clogs.
Feature tseem ceeb:Feem ntau me me nyob rau hauv txoj kab uas hla tshaj li casing (feem ntau yog 2-3/8" rau 4-1/2") thiab nta tshwj xeeb threads (xws li EUE - Sab Nraud Upset End) rau kev sib txuas-pov thawj.

Drill Pipe (Lub Drilling Workhorse)
Drilling yeeb nkab yog ib qho hnyav - lub luag haujlwm, seamless raj siv los tig lub laum me ntsis thiab ncig cov dej drilling ( av nkos ).
Lub hom phiaj:Nws xa cov torque los ntawm qhov chaw rig mus rau lub laum me ntsis hauv qab thiab muab ib txoj hauv kev rau cov av nkos kom txias me ntsis thiab nqa cov pob zeb txiav rov qab rau saum npoo.
Feature tseem ceeb:Nws yuav tsum tiv taus huab cua nruj, torque, thiab sab hauv siab. Cov kav dej laum txuas nrog tshwj xeeb "cov cuab yeej pob qij txha" (threaded ends) uas yog tuab thiab muaj zog dua li cov yeeb nkab lub cev nws tus kheej.
