Cov kav hlau uas siv los txhawb cov phab ntsa ntawm cov qhov roj thiab cov roj av. Txhua lub qhov siv ntau txheej ntawm cov kav hlau nyob ntawm qhov tob thiab qhov av ntawm qhov av. Cov kav hlau tom qab lub qhov siv cov cement rau cov cement, cov kav hlau thiab cov kav dej, cov kav hlau tho qhov sib txawv, nws tsis tuaj yeem siv dua, yog cov khoom siv ib zaug xwb. Yog li ntawd, kev siv cov kav hlau suav txog ntau dua 70% ntawm tag nrho cov kav dej roj. Cov kav hlau tuaj yeem muab faib ua cov kav dej, cov kav hlau saum npoo av, cov kav hlau kev siv tshuab thiab cov kav hlau txheej roj raws li kev siv, thiab lawv cov qauv hauv cov qhov roj tau qhia hauv daim duab.
Cov yeeb nkab: feem ntau yog siv rau hauv dej hiav txwv thiab suab puam drilling, los cais dej hiav txwv thiab xuab zeb, kom ntseeg tau tias qhov drilling du, cov lus qhia tseem ceeb ntawm cov txheej txheem no yog: ∮762mm (30in) × 25.4mm, ∮762mm (30in) × 19.06mm.
Lub plhaub nto: feem ntau yog siv rau thawj qhov kev khawb, khawb cov av mos rau hauv lub hauv paus, txhawm rau kaw qhov av no yam tsis muaj kev tawg, yuav tsum siv lub plhaub nto rau kev kaw. Cov lus qhia tseem ceeb ntawm lub plhaub nto: 508mm (20in), 406.4mm (16in), 339.73mm (13-3/8in), 273.05mm (10-3/4in), 244.48mm (9-5/8in), thiab lwm yam. Qhov tob ntawm cov yeeb nkab nyob ntawm qhov tob ntawm cov khoom mos, uas feem ntau yog 80 ~ 1500m. Nws lub siab sab nraud thiab lub siab sab hauv tsis loj, feem ntau siv K55 steel qib lossis N80 steel qib.
Cov txheej txheem kev siv tshuab: yog siv rau hauv cov txheej txheem drilling ntawm kev tsim cov khoom nyuaj, thaum nws ntsib cov txheej txheem tawg, txheej roj, txheej roj, txheej dej, txheej ploj, txheej ntsev nplaum thiab lwm yam khoom nyuaj, nws yuav tsum tau kaw, txwv tsis pub qhov drilling tsis tuaj yeem ua tiav. Qee lub Qhov Dej tob thiab nyuaj, thiab qhov tob ntawm lub qhov dej yog ntau txhiab meters, qhov dej tob no xav tau ntau txheej ntawm cov txheej txheem kev siv tshuab, nws cov khoom siv kho tshuab thiab kev ua haujlwm sealing siab, kev siv cov qib hlau kuj siab dua, ntxiv rau K55, ntau dua N80 thiab P110 qib hlau, qee lub Qhov Dej tob kuj siv Q125 lossis siab dua uas tsis yog API qib hlau xws li V150. Cov lus qhia tseem ceeb ntawm cov txheej txheem casing yog: 339.73mm (13-3 / 8in), 273.05mm (10-3 / 4in), 244.48mm (9-5 / 8in), 219.08mm (8-5 / 8in), 193.68mm (7-5 / 8in), 177.8mm (7in), thiab lwm yam.
Cov txheej roj casing: Thaum tho qhov rau hauv txheej phiaj (txheej roj thiab roj), nws yog qhov tsim nyog los kaw cov roj thiab roj txheej thiab sab saud uas raug tsim nrog cov roj casing, thiab cov yeeb nkab roj nyob hauv cov roj casing. Hauv txhua hom casing casing, qhov tob ntawm qhov drilling yog qhov tob tshaj plaws, thiab nws cov khoom siv kho tshuab thiab kev ua haujlwm sealing kuj yog qhov siab tshaj plaws. Cov qib hlau yog K55, N80, P110, Q125, V150 thiab lwm yam. Cov lus qhia tseem ceeb ntawm cov reservoir casing yog: 177.8mm (7in), 168.28mm (6-5/8in), 139.7mm (5-1/2in), 127mm (5in), 114.3mm (4-1/2in), thiab lwm yam.
