Cov ntsiab lus ntawm Tubing thiab Casing
Tubing thiab casing yog cov kav hlau siv hauv cov roj drilling. Txawm hais tias ob qho tib si yog cov khoom siv yeeb nkab steel, lawv cov txheej txheem tsim khoom thiab cov qauv kev ua haujlwm txawv heev vim lawv cov ntawv sib txawv hauv kev ua haujlwm drilling.
Kev siv tubing thiab casing
Tubing feem ntau yog siv los thauj cov roj thiab roj los ntawm av mus rau qhov chaw. Nws muaj kev kub siab thiab kev tiv thaiv corrosion, ua kom muaj kev nyab xeeb thiab kev vam meej ntawm cov roj drilling kev ua haujlwm. Casing, ntawm qhov tod tes, yog siv los tiv thaiv lub qhov dej. Vim tias casing nyob ntawm qhov tob dua hauv qhov dej, nws cov kev xav tau siab dua li cov tubing.
Qhov sib txawv ntawm cov txheej txheem tsim khoom
Txawm hais tias tubing thiab casing yuav zoo sib xws, lawv cov txheej txheem tsim txawv heev.
1. Kev xaiv cov khoom sib txawv
Tubing kuj yog thinner, feem ntau yog vim nws qhov siab thiab corrosion kuj, yog li yuav tsum tau tsawg phab ntsa thickness. Casing, txawm li cas los xij, yuav tsum muaj phab ntsa tuab dua li cov tubing vim nws yuav tsum tiv taus siab thiab hnyav dua.
2. Cov txheej txheem tsim khoom sib txawv
Casing ntau lawm yog complex, koom nrog ntau cov yeeb nkab khoov, siab - threading precision, thiab kub dov ntawm seamless steel kav. Nyob rau hauv sib piv, tubing ntau lawm yog yooj yim, feem ntau suav nrog steel yeeb nkab ua, kub dov, thiab casing xov.
3. Cov qauv xeem sib txawv
Tom qab casing ntau lawm, ntau qhov ntsuas xws li xov suav thiab phab ntsa ntom ntom yuav tsum tau kuaj thiab ntsuas, thiab kev ntsuas nruj xws li kev ntsuas siab kuj tseem yuav tsum tau. Tubing, ntawm qhov tod tes, tsuas yog yuav tsum tau soj ntsuam nruj ntawm qee qhov kev ntsuas niaj hnub.
