API 5DP Laum Yeeb NkabPuas yog cov yeeb nkab steel nrog xov xaus, siv txuas rau saum npoo Drilling cov cuab yeej mus rau hauv qab {qhov sib dhos ua ke (BHA) lossis drilling cov cuab yeej ntawm qhov chaw nyob ntawm qhov chaw nyob ntawm qhov chaw nyob ntawm qhov chaw nyob. Lub ntsuas dej tho kev thauj cov av nkos mus rau lub laum me ntsis thiab ua haujlwm nrog me ntsis kom nce, qis dua, lossis tig lub BHA. Nws yuav tsum tau tiv thaiv kev ntxhov siab sab hauv thiab sab nraud, telional rog, khoov, thiab co. Thaum cov roj thiab roj tawm thiab ua kom huv, tho yeeb nkab tuaj yeem siv ntau zaus.

Qib e tho yeeb yaj kiab, xa mus rau "hlau me me", nthuav tawm cov nplooj ntawv qis tshaj plaws muaj zog rau ib qho chaw nrog cov txiaj ntsig lub zog ntawm tsawg dua 80,000 PSI. Nws muaj peev xwm tiv thaiv ntau feem pua ntawm ncab lossis "lim" ua ntej ua ntej ua ke dua cov zog ntsuas cov kab yeeb nkab. Nws kuj tseem tiv taus kev xeb thiab tawg. Qib E yog siv hauv nruab nrab qhov tob tob los ntawm 10,000 mus rau 15,000 ko taw.
Qeb X-95, G-105, thiab S-135 tau txiav txim siab qib siab. Lawv tso tawm cov txiaj ntsig ntau ntxiv lub zog uas yuav tsum tau muab kev pabcuam tob.
Cov Qib
Cov qhab nia tsim nyog feem ntau tshaj cov specifications teev los ntawm API spec 5DP. Lawv cov khoom ua tau zoo txhim kho tau tsim los rau cov kev pab qaub, kev pabcuam tseem ceeb, thiab lwm tus siv {{2} {txhais tau tias yuav tsum tau ua.
QIB Kev Pabcuam Qib Tawm tiv thaiv sulphide kev nyuaj siab corrosion (SSC). SSC tuaj yeem tshwm sim thaum hydrogen sulfide yog tam sim no. Ingress ntawm hydrogen txuas nrog kev ntxhov siab ntau dua, qis kub, qis chloride cov ntsiab lus txo nws tau raug rau tawg thiab tsis ua tiav.
Cov kev pab cuam tseem ceeb tiv thaiv kev corrosion thaum cov roj qab zib lossis cov pa roj carbon dioxide tam sim no. Lawv yog tus nqi hloov kho tau zoo uas siv rau hauv cov ntawv thov kev txhaj tshuaj.
Sizing
Laum yeeb nkab yog tsim raws cov qauv kev qhia thiab raug muab rau hauv cov neeg sawv ntsug. Qhov ob qhov kev ua haujlwm tseem ceeb tshaj plaws yog qhov ntev thiab cov taub.
Qho ntev
Txoj hlua laum yog ua los ntawm ntau ntu ntawm cov yeeb nkab laum. Lo lus "sawv ntsug" yog hais txog ob lossis peb ntu ntawm cov yeeb nkab laum uas tau pub rau hauv lub tsev pheeb suab kom tiav 60 txog 90 ko taw ntawm kev drilling. Txhua ntu ntawm cov yeeb nkab, xa mus rau raws li ib "ib qho", tau cais los ntawm API mus rau hauv peb lub sijhawm sib txawv; R1, R2, thiab R3.
Ntau yam 1 (R1) yog luv tshaj plaws nyob rau hauv ntev, ntau dua rau sizing ntau lawm tubing lossis casing, thiab li 22 ft.
Ntau 2 (R2) yog suav hais tias yog tus qauv ntev rau cov yeeb nkab laum thiab ranges los ntawm 27 txog 31 ft.
Ntau yam 3 (R3) muaj ntau yam nyob rau hauv casing thiab kuj tau xa mus rau hauv kev lag luam drilling dej tob. Cov ntev nce poob qis dua tus naj npawb ntawm cov cuab yeej sib koom ua ke hauv txhua qhov muag ntawm cov yeeb nkab laum. Lub caij nplooj zeeg rov qab hais tias lub nra tau tshoov siab rau txhua lub cuab yeej sib koom tes yog ntau dua nce hnav thiab txo lub neej kev xav tau ntawm cov yeeb nkab laum. R3 ranges los ntawm 38 txog 45 ft.
