Casing:
Casing yeeb nkab yog siv rau hauv ob sab phlu borehole uas tau khawb rau hauv av rau procuring roj los yog roj thiab stabilizing nws. Lub casing yeeb nkab yog raug rau axial tensions thiab siab nyob rau hauv lub siab uas yog generated thaum uas siv roj los yog roj. Lawv kuj yuav tsum tau ris lub siab sab nraud uas tshwm sim los ntawm cov pob zeb nyob ib puag ncig hauv av.
OCTG casing yog qhov loj txoj kab uas hla uas yuav tsum tau cemented rau hauv lub borehole. Txoj kab uas hla ntawm OCTG casing yeeb nkab yog li ntawm 4.5 "mus rau 20". Cov yeeb nkab yog zoo-cemented thiab sawv muaj zog, nws ua raws li cov qauv ntawm lub qhov dej thiab muab qhov kev ncaj ncees. Lub casing tiv thaiv lub qhov dej los ntawm kev sib tsoo thaum cov txheej txheem drilling yog nyob rau. Zoo cemented casing yuav tsum kav lub neej ntawm lub qhov dej.
Casing yuav tsum tau thaum lub sij hawm drilling txheej txheem raws li nws yog tsim nyog rau cov hauv qab no:
tuav rau txoj hlua xyaum, tiv thaiv qhov tsis khov kho sab sauv ntawm qhov dej los ntawm caving hauv
tiv thaiv kab mob
muaj ib lub bore sab hauv uas yooj yim installation ntawm cov khoom siv ntau lawm
tiv thaiv txhua hom kua (roj) poob.
pab kaw cov cheeb tsam uas muaj kev kub ntxhov los ntawm qhov chaw ntawm lub ntiaj teb.
Qhov sib txawv ntawm cov casings yog tus neeg xyuas pib casing, nto casing, intermediate casing, ntau lawm casing, liner thiab liner tieback casing.
Tubing:
Tubing yeeb nkab yog cov yeeb nkab uas muab tso rau hauv lub qhov dej los ntawm cov yeeb nkab casing. Nws yog lub luag haujlwm rau kev thauj mus los ntawm hydrocarbons rau saum npoo. Tubing yeeb nkab yog siv los thauj cov pa roj carbon monoxide lossis roj av tom qab qhov drilling tiav. Nws thauj cov roj thiab roj mus rau cov chaw ua haujlwm ntxiv. Zoo ib yam li cov laum yeeb nkab thiab cov casing, cov yeeb nkab yeeb nkab kuj yuav tsum muaj kev kub siab thaum lub sij hawm rho tawm, thiab yog li lawv yuav tsum tau ua kom tau raws li cov qauv kev lag luam. Tubing yeeb nkab muaj nyob rau hauv ntau qhov ntau thiab tsawg xws li 1 1/4" txog 4.5".
Tubing tiv thaiv lub casing los ntawm hnav thiab tsim kua muag tshwm sim los ntawm corrosive kua, xuab zeb, paraffin, thiab lwm yam. Nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj los yog tawg, tubing yeeb nkab tuaj yeem hloov tau yooj yim.
Kab Yeeb:
Kab yeeb nkab yog cov pa roj carbon steel yeeb nkab uas muaj zog heev uas siv rau kev thauj mus los ntawm ntau yam khoom siv roj av, roj av, roj thiab dej. API 5L yog ib qho tshwj xeeb ntawm American Petroleum Institute uas tswj thiab txheeb xyuas tus qauv rau qhov loj me, lub cev, cov khoom siv thiab tshuaj lom neeg ntawm cov hlau siv rau kev tsim cov kab yeeb nkab. Ntau lub tuam txhab tsim cov yeeb nkab thoob plaws ntiaj teb ua raws li API 5L cov lus qhia rau OCTG kab yeeb nkab siv hauv Kev Lag Luam Roj thiab Roj. OCTG kab yeeb nkab yog muaj nyob rau hauv ntau qhov ntau thiab tsawg ntawm txoj kab uas hla ntawm 2 ntiv mus rau 48 ntiv tes.
Drill pipe:
Drilling yeeb nkab yog seamless yeeb nkab uas yog tig nyob rau hauv thiaj li yuav circulate lub drilling kua. Cov yeeb nkab no muaj txiaj ntsig zoo rau kev siv cov kua dej drilling rov qab rau lub annulus. Lub annulus yog qhov chaw nyob rau hauv cov roj qhov nruab nrab ntawm lub casing thiab cov kav dej. Ib qho yooj yim ncig ntawm cov kua hauv lub qhov dej yog ua tau vim yog lub annulus. Lub laum yeeb nkab yog raug rau axial nro vim hais tias siab torque yuav tsum tau rau rotating lub down-qhov sib dhos thiab drilling cov kua thiab circulating nws. OCTG laum yeeb nkab yuav tsum muaj zog heev vim tias lawv yuav tsum tau dais ntau qhov kev ntxhov siab hauv av. Cov yeeb nkab laum yog siv nyob rau hauv qhov drilling rigs thiab lawv muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab ntau yam zoo. OCTG laum yeeb nkab yuav tsum muaj zog thiab ua tau raws li cov qauv ntawm API 5DP thiab API SPEC 7-1.
Cov yeeb nkab zoo:
Cov yeeb nkab steel yog cov yeeb nkab steel uas tsis tau raug ntsuas siab uas yog siv rau hauv ntau daim ntawv thov thoob plaws ntau yam kev lag luam. Cov yeeb nkab muaj qhov ntau thiab tsawg ntawm 1/2 "mus rau 48" sab nraud thiab nws yog tsim los ntawm carbon, stainless, lossis galvanized steel. Cov yeeb nkab qauv kuj tseem hu ua structural tubing.
HDPE - Poly yeeb nkab:
Poly yeeb nkab, tseem hu ua PE, polyethylene yeeb nkab lossis polyethylene tubing, yog cov yeeb nkab thermoplastic uas hloov tau, hnav, thiab ruaj khov. Nws yog siv rau hauv kev siv xws li dej irrigation, roj kab, slurry thauj, cable conduits thiab lwm yam. Baker Tubulars nqa poly yeeb nkab xws li 1 "mus rau 12" hauv txhua qib SDR.
Raws li cov kws tshaj lij thiab cov chaw tsim khoom ntawm cov kav dej, txhua yam khoom tsim los ntawm Vigor yuav raug tsim thiab tshuaj xyuas nruj raws li API cov qauv lossis cov qauv kev lag luam siab dua. OCTG cov kav dej uas tsim los ntawm Vigor tau dhau los lees paub tias yog cov khoom lag luam zoo thiab ruaj khov hauv kev lag luam roj thiab roj.
