CMC (Carboxymethyl cellulose) yog cov tshuaj siv cov tshuaj tua neeg siv nyob rau hauv cov roj drilling kev lag luam, feem ntau yog cov tuab thiab stabilizer rau drilling kua. Nws cov kev cuam tshuam rau kev drilling efficiency thiab tuaj yeem tham los ntawm kev txhim kho cov kua dej, thiab ua kom zoo rau cov txheej txheem drilling.
1. Cov haujlwm yooj yim ntawm CMC
thickening nyhuv
CMC tuaj yeem ua kom nce cov viscosity ntawm drilling kua. Cov cuab yeej no yog qhov tseem ceeb rau kev ua haujlwm drilling vim tias cov kua dej tuab thiab tuaj yeem muab kev txiav tawm ntawm kev txiav tawm ntawm qhov chaw nkaum thiab tiv thaiv lawv cov nyiaj tau. Nyob rau tib lub sijhawm, siab tshaj viscosity pab kom muaj kev tshem tawm zoo hauv cov kev tsim ua kom zoo thiab tiv thaiv kev txiav tawm los ntawm kev txhaws ntawm qhov chaw nkaum.
kua ruaj khov
CMC muaj cov dej ua kom muaj zog thiab kub thiab txias thiab ntsev tsis kam, uas tso cai rau nws ua haujlwm stably nyob rau hauv cov kev sib txawv ntawm geological. Nws cov tshuaj zoo heev thiab lubrication cov teeb meem txo ntau yam teeb meem tshwm sim los ntawm qhov tsis muaj zog ntawm cov txheej txheem drowitation, xws li mud nag lossis roj khiav, thiab lwm yam.
Txo cov dej ntws ntawm cov av nkos
Los ntawm kev sib xyaw nrog lwm cov Cheebtsam, cml tuaj yeem txo cov lim dej, ua kom muaj kev puas tsuaj rau cov txheej txheem hluav taws xob, tiv thaiv cov phab ntsa kom zoo, thiab yog li txhim kho kev siv hluav taws xob.
2. Cov kev cuam tshuam tshwj xeeb ntawm CMC ntawm Drilling Efficiency
Txhim kho kev tu huv kev ua haujlwm ntawm cov kua dej drilling
Thaum lub sijhawm drilling, kev sib txhuam ntawm cov laum me ntsis thiab cov tsim yuav tsim cov nyiaj ntau ntawm kev txiav. Yog tias lawv tsis tuaj yeem raug tshem tawm hauv lub sijhawm, nws yuav ua rau muaj kev cuam tshuam rau kev ua haujlwm drilling. CMC Txhim kho qhov kev ncua thiab nqa tau muaj peev xwm khiav cov dej lim dej, uas tuaj yeem coj cov cuttings tawm ntawm lub wellhead kom ntseeg tau tias qhov kev nyiam huv ntawm qhov chaw ua kom huv. Txoj haujlwm no tseem ceeb tshaj plaws rau cov khoom siv tau zoo xws li cov dej tob tob, cov dej tob tob, thiab cov kab rov tav. Nws tuaj yeem zam kev teeb meem xws li HeBorore clogging thiab me ntsis sticking, yog li ntau zuj zus drilling ceev.
Txo txoj kev pheej hmoo ntawm cov txheej txheem sib tsoo
Hauv qee qhov muag muag lossis xoob xoob pob zeb, ib qho ntawm cov haujlwm tseem ceeb ntawm cov kua dej drilling yog txhawm rau tswj qhov ruaj ntseg ntawm phab ntsa. Raws li cov tuab dua, cmc tuaj yeem txhim kho cov nplaum ntawm cov kua dej drilling los ntawm phab ntsa zoo los tiv thaiv lub phab ntsa lossis cov av nkos los ntawm cov chaw dav dav. Qhov no tsis tsuas yog txhim kho kev nyab xeeb ntawm kev ua haujlwm drilling, tab sis kuj txo qis downtime tshwm sim los ntawm phab ntsa ruaj khov, yog li kev txhim kho drilling efficiency.
Txo cov kua dej poob
Thaum lub sij hawm drilling, drilling kua yuav nkag mus rau hauv cov av nyob, tshwj xeeb tshaj yog nyob rau thaj chaw uas pob zeb muaj siab ntsws lossis pob txha. CMC tuaj yeem tswj tau cov kua dej poob ntawm cov kua dej thiab txo cov kev poob ntawm cov kua dej hauv pores thiab pob txha lov. Qhov no tsis tsuas yog pab tau DROUNDING DEJ DABNEEG, tab sis kuj tseem yuav tau muab cov kua dej tsis ntev thiab ua rau cov kua dej nrawm nroos kom ua nws txoj haujlwm zoo.
Txhim kho kev ua haujlwm zoo thiab ua kom luv luv drilling
Vim tias cmc txhim kho cov kev ua tau zoo ntawm cov kua dej, nws ua tau zoo dua hauv kev ua kom muaj teeb meem, yog li txo cov teeb meem zoo thaum lub sijhawm drilling ua haujlwm yuav ua tau smoother. thiab ua tau zoo. Qhov kev ruaj ntseg thiab kev tu cov kev ua tau zoo ntawm cov kua dej sib tsoo cuam tshuam rau kev nce qib ntawm kev ua haujlwm. Kev siv CMC nce lub tshuab khiav ceev, yog li ua kom tsis txaus lub tshuab khiav thiab txo cov nqi ua haujlwm tag nrho.
3. Cov ntawv thov piv txwv thiab cov kev coj ua ntawm CMC
Qhov nqus tau zoo tob
Nyob rau hauv cov dej tob tob, raws li kev nqus qhov tob zuj zus thiab lub hehead siab nce, qhov ruaj khov thiab ncua ntawm cov dej drilling yog qhov tshwj xeeb. Los ntawm kev ntxiv cmc, lub viscosity ntawm cov kua dej drilling tuaj yeem txhim kho, lub peev xwm nqa tau tuaj yeem txhim kho tuaj yeem kho tau, thiab cov kua dej sib zog ntawm cov kua dej sib xyaw tuaj yeem ua kom zoo nkauj. Ib qho ntxiv, CMC muaj peev xwm txo lub sijhawm pov tseg los ntawm kev nyab xeeb phab ntsa thiab to kev ua haujlwm ntawm kev ua tau zoo ntawm kev ua haujlwm zoo.
Qhov Kub thiab Kub Thiab Kev Siab Siab Tsim Drilling
Hauv kev tsim cov kev tsim muaj qhov kub thiab kub siab, tho qhov dej yuav tsum muaj siab thermal ruaj khov thiab siab kuj. CMC tsis tuaj yeem tsuas yog ua rau muaj cov nyhuv tsuas yog siv cov nyhuv tuab tuab ntawm qhov kub thiab txias, tab sis tseem tswj kom muaj kev ruaj khov nyob hauv ib puag ncig kub kom tsis txhob muaj kev cuam tshuam dej lim. Hauv kev siv cov tswv yim, cmc txo cov kua dej poob thaum lub sij hawm khiav tawm hauv cov tsim thiab txo qis qis los ntawm cov kua dej.
Kab rov tav zoo drilling
Thaum lub sij hawm drilling txheej txheem ntawm kab rov tav thiab sab nraud ntawm phab ntsa zoo thiab tshem tawm ntawm cuttings tshwj xeeb, kev siv ntawmCmc Raws li cov tuab muaj cov teeb meem tseem ceeb. CMC muaj peev xwm txhim kho cov rheyology ntawm drilling kua, kom tsis txhob muaj teeb meem xws li daig thiab kev sib tw, thiab txhim kho kev ua tau zoo ntawm kev siv kab rov tav zoo.
Raws li cov kua dej ua kom zoo ntxiv, cmc daim ntawv thov hauv cov txheej txheem drilling tseem ceeb txhim kho kev ua haujlwm. Los ntawm kev txhim kho lub viscosity, kev ruaj khov thiab rheological cov khoom siv ntawm kev ntxuav kom zoo nkauj, muab cov dej sib tsoo zoo, thiab ua kom qeeb dua. Nrog kev tsim kho cov thev naus laus zis ntawm cov tshuab drilling, CMC muaj cov kev cia siab uas muaj kev cia siab thiab yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm yav tom ntej drooring.
