Raws li lub tuam txhab muaj kev paub txog kev drilling, Vigor tau muaj lub sijhawm los ua haujlwm nrog ob qho tib si txheej txheem laum yeeb nkab thiab hnyav hnyav laum yeeb nkab (HWDP) hla ntau qhov kev tsim kho qhov dej. Thaum ob hom tubulars sib koom qee qhov zoo sib xws, muaj qhov sib txawv uas yog qhov tseem ceeb kom nkag siab thaum tsim thiab ua tiav cov haujlwm drilling zoo.
Drill Pipe vs. Heavy Weight Drill Pipe
Ntawm nws cov tub ntxhais, lub laum yeeb nkab yog ib qho tseem ceeb ntawm txoj hlua laum, ua tus thawj conduit rau kev xa cov rotational torque thiab axial load los ntawm qhov chaw mus rau lub laum ntsis. Ob qho tib si tus qauv tho yeeb nkab thiab HWDP ua tiav lub luag haujlwm tseem ceeb no, tab sis lawv cov khoom tshwj xeeb thiab lub peev xwm txawv qhov txawv.
Standard laum yeeb nkab feem ntau yog tsim los ntawm high-strength, low-alloy steel qib zoo li Qib E los yog Qib X. Cov kav dej no yog tsim los ua kom muaj kev sib npaug ntawm lub zog, ductility, thiab nqi-zoo, ua rau lawv haum rau ntau yam ntawm drilling. daim ntawv thov.
Ntawm qhov tod tes,hnyav hnyav laum yeeb nkabyog ib hom tshwj xeeb ntawm tubular engineered los muab lub zog siab dua, nce qhov hnyav, thiab txhim kho qhov tawv nqaij piv rau cov qauv tho yeeb nkab. Qhov no yog ua tiav los ntawm kev siv cov qib hwm alloy steel thiab cov txheej txheem kev kho cua sov tshwj xeeb.
Cov txheej txheem tsim khoom
Cov txheej txheem metallurgy thiab kev tsim khoom sib txawv ua haujlwm hauv kev tsim HWDP yog qhov tseem ceeb rau nws cov khoom tshwj xeeb. Ib qho ntawm cov qib feem ntau siv rau HWDP yog S-135, uas yog lub zog siab, qis-alloy steel nrog qhov tsawg kawg nkaus lub zog ntawm 135,000 psi (930 MPa). Lwm cov qib hwm zoo li V-150 thiab X-160 muaj peev xwm muaj zog dua.
Txhawm rau ua tiav cov qib siab zog no, HWDP tau txais cov txheej txheem kho cua sov tshwj xeeb, xws li quenching thiab tempering, uas ua kom cov hlau tsis zoo thiab txhim kho nws cov khoom siv kho tshuab. Tsis tas li ntawd, HWDP feem ntau nta cov phab ntsa thicknesses piv rau cov txheej txheem laum yeeb nkab ntawm tib txoj kab uas hla sab nraud, ua rau nws qhov hnyav nce thiab nruj.
Heavy weight laum yeeb nkab Nyhav ib ko taw thiab tawv:
Thawj qhov sib txawv ntawm tus qauv laum yeeb nkab thiab HWDP yog lawv qhov hnyav thiab qhov nruj ntawm ib ko taw. Thaum tus qauv 5-inch laum yeeb nkab yuav hnyav li ntawm 19.5 phaus ib ko taw (29 kg / m), 5-inch HWDP tuaj yeem hnyav li ntawm 28-32 phaus ib ko taw ({{6} } kg / m), nyob ntawm seb cov qib tshwj xeeb thiab phab ntsa thickness.
Qhov hnyav nce no txhais mus rau qhov hnyav dua ntawm me ntsis (WOB), uas yog qhov tseem ceeb rau kev nkag mus rau qhov nyuaj thiab abrasive formations los yog thaum drilling directional lossis kab rov tav qhov dej. Qhov ntxiv txhav ntawm HWDP kuj tseem pab tswj kom zoo dua qhov tu, txo qhov kev pheej hmoo ntawm cov teeb meem ntawm cov yeeb nkab, thiab tswj cov downhole vibrations, uas tuaj yeem ua rau kev xyaum ua haujlwm ntxov ntxov.
Daim ntawv thov:
Kev xaiv ntawm tus qauv laum yeeb nkab thiab HWDP feem ntau yog tsav los ntawm daim ntawv thov tshwj xeeb drilling thiab cov kev cov nyom uas xav tau thoob plaws hauv txoj kev tsim kho qhov dej. Nyob rau hauv dav dav, tus qauv laum yeeb nkab yog haum rau ntau cov pa ntsug thiab directional drilling scenarios qhov twg cov formations kuj mos thiab cov zoo trajectories tsis heev complex.
Txawm li cas los xij, thaum drilling los ntawm cov tawv tawv thiab abrasive formations, xws li quartzite, basalts, los yog compacted shales, los yog thaum tackling txuas mus txog los yog kab rov tav zoo profiles, lub peev xwm ntawm HWDP ua tau zoo heev. Qhov hnyav ntxiv thiab qhov tawv nqaij uas muab los ntawm HWDP tuaj yeem txhim kho tus nqi nkag mus (ROP), txo qis lub sijhawm tsis muaj txiaj ntsig, thiab txo qis qhov pheej hmoo cuam tshuam nrog rau qhov nyuaj drilling qhov chaw.
Thaum HWDP muaj qhov zoo ntawm kev ua tau zoo, nws qhov hnyav thiab qhov hnyav kuj tseem xav tau cov txheej txheem tuav thiab tu tshwj xeeb. Cov cuab yeej nqa tau zoo, xws li cov cuab yeej tshwj xeeb cov yeeb nkab tuav thiab cov cranes uas muaj peev xwm txaus, yuav tsum tau siv los xyuas kom muaj kev nyab xeeb ntawm kev tuav hauv pem teb.
Raws li lub chaw tsim khoom ntawm cov cuab yeej drilling, peb pab neeg lub luag haujlwm yog kom pom zoo thiab muab tus nqi zoo tshaj plaws laum txoj hlua teeb tsa uas tuaj yeem muaj kev nyab xeeb thiab ua tau raws li lub hom phiaj xav tau tom qab paub txog cov kev cai tshwj xeeb, tsim cov yam ntxwv, thiab cov kev cov nyom uas xav tau. Qee qhov xwm txheej, kev sib xyaw ua ke ntawm cov txheej txheem laum yeeb nkab thiab HWDP tej zaum yuav yog qhov kev daws teeb meem zoo tshaj plaws, kev siv zog ntawm txhua hom tubular ntawm ntau theem ntawm txoj kev tsim kho zoo.
