Cov qib laum yeeb nkab suav nrog cov qib API txheem (E-75, X-95, G-105, & S-135), nrog rau cov qib muaj tswv.
API Qib Drill Pipe
API SPEC 5DP qhia txog cov txheej txheem kev xa khoom rau steel laum-pipes nrog chim siab cov yeeb nkab-lub cev kawg thiab vuam-ntawm cov cuab yeej sib txuas rau kev siv hauv kev drilling thiab kev tsim khoom hauv kev lag luam roj av thiab cov nkev lag luam rau peb cov khoom tshwj xeeb (PSL-1 , PSL-2 thiab PSL-3). PS-1 qhia txog phab ntsa tuab, qhov cuam tshuam lub zog, thiab cov kev xav tau lub zog muaj zog tshwj xeeb rau cov khoom siv qib. Cov qib tshwj xeeb PL-2 / PL-3 muaj qhov yuav tsum tau ua ntxiv.

Qib Elaum yeeb nkab, hu ua "mob" steel, nthuav tawm lub zog qis tshaj plaws hauv ib cheeb tsam nrog lub zog tawm los tsawg dua 80, 000 psi. Nws muaj peev xwm tiv taus qhov feem pua ntawm kev ncab lossis "strain" ua ntej tawg dua li cov qib siab dua cov yeeb nkab. Nws kuj tseem tiv taus corrosion thiab tawg. Qib E yog siv hauv qhov nruab nrab qhov tob ntawm 10, 000 txog 15, 000 ko taw.
Qib X-95, G-105, thiab S-135raug suav hais tias yog qib siab zog. Lawv nthuav tawm lub zog tawm los ntxiv uas yuav tsum tau ua rau kev pabcuam tob tob.
Cov Qib Muaj Cai
Cov qib muaj tswv feem ntau tshaj li cov lus qhia tau teev tseg los ntawm API SPEC 5DP. Lawv cov khoom ua tau zoo dua qub yog tsim los rau cov kev pabcuam qaub, kev pabcuam tseem ceeb, thiab lwm yam kev xav tau ntawm cov neeg siv.
Kev pabcuam qaubCov qib tiv thaiv sulfide kev nyuaj siab corrosion (SSC). SSC tuaj yeem tshwm sim thaum muaj hydrogen sulfide. Kev nkag siab ntawm hydrogen ua ke nrog kev ntxhov siab ntau dua, qhov kub tsis tshua muaj, pH tsis tshua muaj, thiab cov ntsiab lus chloride siab txo qis cov ductility ntawm cov qib steel ua rau lawv muaj kev cuam tshuam rau kev tawg thiab tsis ua haujlwm.
Kev pabcuam tseem ceebCov qib tiv thaiv corrosion thaum cov roj qab zib lossis cov pa roj carbon dioxide siab. Lawv yog ib qho txiaj ntsig zoo uas siv rau hauv cov ntawv thov dej.
Qhov loj me
Laum yeeb nkab yog tsim raws li tus qauv specifications thiab muaj nyob rau hauv nominal ntau thiab tsawg. Qhov thib ob qhov tseem ceeb tshaj qhov tshwj xeeb yog qhov ntev thiab txoj kab uas hla.
Ntev
Lub laum txoj hlua yog tsim los ntawm ntau ntu ntawm cov yeeb nkab laum. Lo lus "sawv" yog hais txog ob lossis peb ntu ntawm cov yeeb nkab laum uas tau pub rau hauv qhov dej kom tiav 60 mus rau 90 feet ntawm qhov drilling. Txhua ntu ntawm cov yeeb nkab, hu ua "ib zaug", yog cais los ntawm API rau hauv peb qhov ntev ntev; R1, R2, thiab R3.
Range 1 (R1) yog luv tshaj plaws nyob rau hauv ntev, ntau dua rau sizing ntau lawm tubing los yog casing, thiab ranges ntawm 18 mus rau 22 ft.
Range 2 (R2) yog suav tias yog tus qauv ntev rau cov yeeb nkab laum thiab thaj tsam ntawm 27 txog 31 ft.
Range 3 (R3) yog ib txwm muaj nyob rau hauv casing thiab tseem siv rau hauv cov dej sib sib zog nqus daim ntaub ntawv. Qhov ntev ntev txo cov cuab yeej sib koom ua ke hauv txhua qhov chaw ntawm cov yeeb nkab laum. Lub caij nplooj ntoos zeeg rov qab yog tias cov khoom siv tau tawm ntawm txhua lub cuab yeej sib koom ua ke ntau dua hnav thiab txo qhov kev cia siab lub neej ntawm cov yeeb nkab laum. R3 thaj tsam ntawm 38 mus rau 45 ft.
Txoj kab uas hla
Sab nraud txoj kab uas hla (OD) ntawm lub laum yeeb nkab yog muaj nyob rau hauv nominal qhov ntau thiab tsawg xws li ntawm {{0}}/8" mus rau 6 5/8". Txoj kab uas hla ntawm cov yeeb nkab yog xaiv raws li lub borehole txoj kab uas hla. Txhawm rau kom muaj txiaj ntsig zoo ntawm cov av nkos drilling thiab txo qhov poob siab, qhov sib piv ntawm cov yeeb nkab laum sab nraud rau lub qhov taub yuav tsum yog li 0.6.
Raws li ib qho ntawm cov kws tshaj lij laum yeeb nkab manufacturers, Vigor yuav ib txwm ua raws li qhov zoo thiab kev pabcuam los txhawb cov neeg siv khoom, muab cov neeg siv khoom zoo tib lub sijhawm, muab peb cov neeg siv khoom nrog kev sib raug zoo thiab kev pabcuam zoo tshaj plaws thiab tshuaj xyuas. cov kev pabcuam, kom cov khoom tuaj yeem tuaj txog ntawm cov neeg siv khoom hauv lub xeev zoo tshaj plaws thiab siv tau.
