Casing Yeebyog siv los txhawb cov roj, roj qhov dej ntawm cov yeeb nkab steel, txhawm rau ua kom cov txheej txheem drilling thiab ua tiav ntawm tag nrho qhov dej tom qab kev ua haujlwm ib txwm muaj. Txhua qhov dej muaj ob peb txheej ntawm casing nyob ntawm qhov tob drilling thiab geology. Casing cia siv cov cement cementing, nws thiab cov tubing, laum yeeb nkab sib txawv, tsis tuaj yeem rov qab siv dua, ib qho - lub sij hawm siv cov khoom siv. Yog li ntawd, lub casing ntawm tag nrho cov kev siv ntawm ntau tshaj 70% ntawm cov qhov dej. Casing raws li kev siv yuav muab faib ua: catheter, nto casing, casing tshuab thiab roj casing.
Cov yeeb nkabyog lub conduit los ntawm cov roj thiab roj yog coj los ntawm cov tsim formations mus rau lub teb nto chaw rau kev ua. Tubing yuav tsum muaj zog txaus los tiv thaiv kev thauj khoom thiab deformations cuam tshuam nrog kev tsim khoom thiab kev ua haujlwm. Tsis tas li ntawd, tubing yuav tsum muaj qhov loj me los txhawb qhov kev xav tau ntawm kev tsim cov roj thiab roj. Kom meej meej, tubing uas me dhau txwv kev tsim khoom thiab kev lag luam tom qab ntawm qhov dej. Tubing uas loj dhau lawm, txawm li cas los xij, yuav muaj kev cuam tshuam nyiaj txiag tshaj li tus nqi ntawm txoj hlua tubing nws tus kheej, vim hais tias cov tubing loj yuav cuam tshuam rau tag nrho cov casing tsim ntawm lub qhov dej.
API Tubing Pipe Loj:API Tubing ib txwm muaj txoj kab uas hla me dua li casing, tshwj tsis yog rau 4 1/2-inch inch. Ib txoj kab uas hla sab nraud ntawm 114.3 hli (4 1/2 ntiv tes) raug suav hais tias yog qhov pib thiab tuaj yeem ua tau casing lossis tubing. Txhua yam me me hu ua tubing, txhua yam loj dua yog casing.
Casing Pipe Manufacturing Txheej txheem:
Hlau ingot cua sov → hydraulic punching → reheating → extension → periodic dov → reheating → sizing → txias → straightening → yeeb nkab txiav → tshuaj xyuas
1. Lub qhov cub hluav taws xob annular yog yuav tsum tau rau cov cua sov ingot;
2. Punching thiab reheating nrog hydraulic xovxwm;
3. Cov roj casing cog siv ob lub - cov menyuam phau ntawv qhia phaj txuas ntxiv rau kev txuas ntxiv;
4. Re-siv lub qhov cub cua sov rau lub sij hawm dov, thiab siv lub qhov cub uas tsis yog- nkag rau hauv qhov cub kom rov ua kom sov, txias, ncaj, txiav cov yeeb nkab, thiab tshuaj xyuas.
