Thawj qhov sib txawv ntawmTshiabthiabHwmlaum yeeb nkab nyob rau hauv lawvsiv keeb kwmthiabseem phab ntsa thickness (RWT). Txawm hais tias ob qho tib si suav hais tias yog siab - zoo thiab muaj kev nyab xeeb rau kev drilling, lawv muaj cov kev txwv sib txawv thiab cov cim cim.
Tshiab vs. Hwm: Koj Yuav Txuag Li Cas? Tau txais tus nqi sib piv hnub no.
New Drill Pipe
Txhais:Cov yeeb nkab uas tau tuaj ncaj qha los ntawm lub tshuab tsim thiab tsis tau siv rau hauv qhov dej.
Phab ntsa seem Thickness (RWT):Nws muaj100%ntawm nws thawj nominal phab ntsa thickness (xws li me me raug tolerances).
Kev txheeb xyuas:Feem ntau muajtsis muaj xim bands. Nws raug txheeb xyuas los ntawm lub Hoobkas "mill stencil" (cov ntawv pleev xim rau) thiab cov cim kos rau ntawm cov cuab yeej pob qij txha.
Kev ua tau zoo:Muab qhov siab tshaj plaws tensile lub zog, torsional tawm los, thiab sab hauv siab tsis kam.
Daim ntawv thov:Feem ntau yog siv rau qhov chaw huab cua xws li ultra- qhov dej tob, qhov tob tob, lossis High-Pressure High-Temperature (HPHT) qhov dej uas qhov kev nyab xeeb yog qhov tseem ceeb.
Premium Drill Pipe
Txhais:Siv cov yeeb nkab uas tau dhau los ua qhov tsis zoo -Kev Ntsuas Kev Ntsuas Hluav Taws Xob (NDT)-xws li kev tshuaj xyuas ultrasonic lossis electromagnetic- kom paub tseeb tias nws tseem muaj suab nrov.
Phab ntsa seem Thickness (RWT):Yuav tsum khaws tsawg kawg80%ntawm nws thawj nominal phab ntsa thickness. Yog hais tias phab ntsa thickness poob qis dua 80%, nws yog downgraded rau Class 2.
Kev txheeb xyuas:Kev lag luam tus qauv cim yogob kab dawb.
Kev ua tau zoo:Lub zog yog kwv yees li 80% ntawm cov yeeb nkab tshiab. Thaum thinner, nws tseem muaj zog txaus rau feem ntau cov txheej txheem drilling.
Daim ntawv thov:Qhov no yog qhov"kev lag luam ua haujlwm."Feem ntau ntawm cov txheej txheem onshore thiab offshore drilling tej yaam num siv Premium yeeb vim hais tias nws muab ib tug pov thawj theem ntawm kev nyab xeeb ntawm tus nqi qis dua yuav tshiab.
Phab ntsa seem Thickness (RWT)
New Drill Pipe:Muaj100%ntawm nws thawj nominal phab ntsa thickness (yuav tsum tau ib tug me me raug kam rau ua ntawm -12.5%). Nws nyob ntawm nws qhov siab tshaj plaws ntawm cov qauv siv zog.
Premium Drill Pipe:Tau hnav los ntawm kev sib txhuam tawm tsam phab ntsa borehole tab sis yuav tsum khaws ciatsawg kawg yog 80%ntawm nws thawj phab ntsa thickness. Yog tias nws poob rau 79%, nws tsis yog "Premium."
Siv Keeb Kwm
Tshiab:Ncaj nraim los ntawm kev tsim khoom zeb. Nws yeej tsis tau siv downhole.
Hwm:"Siv" lub cev. Nws tau raug siv hauv kev ua haujlwm drilling tab sis tau dhau los ua qhov tsis zoo -kev kuaj kev puas tsuaj (NDT)- xws li kev tshuaj xyuas ultrasonic lossis electromagnetic- los ua pov thawj nws tseem ua tau raws li 80% qhov pib.
Identification (Xim Bands)
Tshiab:Feem ntau tsis muaj xim bands. Nws raug txheeb xyuas los ntawmzeb stencil(cov ntawv pleev xim rau ntawm cov yeeb nkab) thiab stamped cim rau ntawm lub cuab yeej sib koom.
Hwm:Txheeb xyuas los ntawmob kab dawbpleev xim rau ntawm cov yeeb nkab lub cev (feem ntau nyob ze ntawm qhov chaw lossis cov cuab yeej sib koom ua ke).
Mechanical Performance
Vim tias cov yeeb nkab hwm yog nyias dua li Cov yeeb nkab Tshiab, nws cov kev txwv tsis pub muaj qis dua:
Tensile zog:Cov yeeb nkab hwm tuaj yeem txhawb nqa qhov hnyav dua li Cov yeeb nkab tshiab ua ntej ncab lossis snapping.
Torsional Yield:Cov yeeb nkab hwm muaj qhov txwv qis dua, txhais tau tias nws muaj kev cuam tshuam ntau dua rau "twisting off" nyob rau hauv kev ntxhov siab.
Sab hauv siab:Cov yeeb nkab tshiab muaj qhov ntsuas tawg ntau dua piv rau Premium.

FAQ
Dab tsi yog premium laum yeeb nkab?
Premium laum yeeb nkab yog hais txog laum yeeb nkab tsim nrogTxhim kho threading specificationsuas tshaj li API cov cai.
Yuav ua li cas txheeb xyuas S qib thiab G qib laum yeeb nkab?
kom paub qhov txawvS135thiab G105 laum kav ib API 5DP: S135 yog cim "S135" thiab siv rau ultra-sib sib zog nqus, siab-stress wells (piv txwv li, kab rov tav drilling), nrog min yield zog ntau dua los yog sib npaug rau 135,000 psi thiab tensile zog Ntau dua los yog sib npaug rau 0014 SC TIAB SA 0177). G105 yog cim "G105" rau qhov nruab nrab- qhov tob tob (tsawg dua lossis sib npaug li 6,000m), nrog rau min yield Ntau dua lossis sib npaug rau 105,000 psi thiab tensile Ntau dua lossis sib npaug rau 115,000 psi, tsis tas yuav tsum muaj tshuaj tiv thaiv{{23}.}sulfur test (58 lus)
