OCTGsawv rauRoj Lub Tebchaws Tubular Khoom. Cov no yog tsev neeg ntawm cov kav hlau tshwj xeeb uas siv rau hauv qhov drilling, ua tiav, thiab tsim cov roj thiab cov qhov dej.
OCTG kav tau muab faib ua peb hom kev ua haujlwm tseem ceeb:Drill Pipe, Casing, thiabTubing.
Xav tau ib pob OCTG tag nrho?Tau txais ib qho kev sib sau ua ke rau Drill Pipe, Casing, thiab Tubing hauv ib qho chaw.
Drill Pipe (Tuam Tshoj)
Cov yeeb nkab laum yog qhov hnyav - lub luag haujlwm, seamless yeeb nkab siv los tig lub laum me ntsis thiab ncig cov dej drilling ( av nkos ). Nws yog qhov "active" tshaj plaws ntawm peb hom.
Muaj nuj nqi:Transmits torque los ntawm qhov chaw mus rau me ntsis thiab xa av nkos kom txias me ntsis thiab nqa cuttings rov qab mus rau saum npoo.
Feature tseem ceeb:Nws yogrov siv tau. Thaum ib ntu yog drilled, cov yeeb nkab yog rub tawm thiab khaws cia rau qhov project tom ntej.
Cov khoom sib txuas:Nta "Tool Joints"-thickened, siab-strength threaded ends tsim los tiv taus ntau pua ua-thiab- tawg cycles.
Specification:Tswj los ntawmAPI 5 DP.
Casing Pipe (Permanent Structure)
Casing yog cov qauv "phab ntsa" ntawm lub qhov dej. Nws yog ib tug loj - txoj kab uas hla cov yeeb nkab uas yog txo mus rau hauv lub qhib borehole thiab cemented nyob rau hauv qhov chaw.
Muaj nuj nqi:
Tiv thaiv lub qhov dej los ntawm kev sib tsoo.
Tiv thaiv dej hauv av los ntawm kev sib kis.
cais thaj chaw siab sib txawv.
Feature tseem ceeb:Nws yogruaj khov. Thaum cemented, nws tseem nyob hauv qhov dej mus ib txhis.
Hom kev ua haujlwm:
Tus neeg xyuas pib:Cov yeeb nkab sab nraud tiv thaiv sab saum toj - qhov tsua -ins.
Nto:Tiv thaiv cov khaubncaws sab nraud povtseg.
Nruab nrab:Tswj siab - thaj chaw siab hauv qhov dej tob.
Kev tsim tawm:Txheej kawg uas tiv thaiv thaj chaw tsim khoom.
Specification:Tswj los ntawmAPI 5 CT.
Tubing Tube (Cov Khoom Siv Hluav Taws Xob)
Tubing yog "straw" uas zaum hauv lub casing. Nws yog cov yeeb nkab uas cov roj los yog roj yeej ntws mus rau saum npoo.
Muaj nuj nqi:Ua kua dej los ntawm lub reservoir mus rau lub qhov dej.
Feature tseem ceeb:Nws yogtshem tau / hloov tau. Tsis zoo li casing, tubing tsis cemented. Yog tias nws corrodes los yog txhaws, nws tuaj yeem rub tawm thiab hloov.
Loj:Feem ntau me dua li casing (feem ntau 2-3/8 "rau 4-1/2").
Specification:Tswj los ntawmAPI 5 CT.
Couplings thiab Connectors
Thaum tsis yog "pipe" lawv tus kheej, lawv yog ib feem tseem ceeb ntawm OCTG tsev neeg.
Standard Couplings:Lub tog raj kheej luv siv los koom nrog ob qhov ntev ntawm lub casing lossis tubing.
Kev sib txuas hwm hwm:Tshwj xeeb, roj- nruj threads siv rau siab -siab los yog siab-kub (HPHT) qhov dej uas txheem threads yuav to.
Qhov tseem ceeb Distinctions los ntawm ib puag ncig (Qib)
OCTG yog ntxiv categorized los ntawmQib, uas txiav txim siab cov yeeb nkab lub zog thiab tshuaj tiv thaiv:
| Ib puag ncig | Cov Qib Siab | Qhov Tseem Ceeb |
| "Sweet" Service | J55, K55, N80, P110 | Lub zog yog qhov tseem ceeb; tsis muaj H2S tam sim no. |
| "Siab" Service | L80, C90, T95, C110 | Corrosion Resistance. Yuav tsum tiv thaiv Hydrogen Sulfide (H2S) tawg. |
| Sib sib zog nqus/siab | P110, Q125 | Lub zog tawm los heev los txhawb qhov hnyav ntawm txoj hlua ntev ntev. |

FAQ
OCTG txhais li cas?
OCTGsawv rauRoj Lub Tebchaws Tubular Khoom. Nws yog ib lub sij hawm sib sau ua ke rau cov kav dej tshwj xeeb uas siv rau hauv qhov drilling, ua tiav, thiab tsim cov roj thiab cov qhov dej.
OCTG siv rau dab tsi?
OCTG(Oil Lub Tebchaws Tubular Khoom) cov kav dej yog siv rau covdrilling, tiav, thiab ntau lawmntawm cov roj thiab roj qhov dej.
Muaj peb yam tseem ceeb siv:
Drilling: Laum cov kav dejyog siv los tig lub laum me ntsis thiab circulate kua los tsim lub qhov dej.
Kev them nyiaj yug tus qauv: Cov kav dejkab lub qhov dej kom tiv thaiv nws los ntawm kev sib tsoo, cais thaj chaw siab, thiab tiv thaiv cov dej hauv av los ntawm kev sib kis.
Kev tsim tawm: Cov kav dejua raws li "conduit" lossis straw uas coj cov roj thiab roj los ntawm cov dej hauv av mus rau saum npoo.
