CMC (Carboxymethyl Cellulose) yog ib qho tshuaj additive lug siv nyob rau hauv cov roj drilling kev lag luam, feem ntau yog ib tug thickener thiab stabilizer rau drilling kua. Nws qhov cuam tshuam rau kev ua haujlwm ntawm qhov drilling yog ntau yam thiab tuaj yeem sib tham los ntawm qhov kev xav ntawm kev txhim kho cov dej drilling, txo cov teeb meem thaum lub sij hawm drilling, thiab optimizing cov txheej txheem drilling.
1. Cov haujlwm tseem ceeb ntawm CMC
thickening nyhuv
CMC tuaj yeem ua kom cov viscosity ntawm cov dej drilling. Cov cuab yeej no yog qhov tseem ceeb rau kev ua haujlwm drilling vim tias cov kua dej tuab tuab tuaj yeem muab kev nqa tau zoo dua thiab muaj peev xwm thauj khoom, pab tshem tawm cov txiav los ntawm qhov dej thiab tiv thaiv lawv cov deposition. Nyob rau tib lub sijhawm, siab dua viscosity pab tswj kev ncua zoo hauv cov txheej txheem nyuaj thiab tiv thaiv kev txiav los ntawm clogging lub qhov dej.
kua stability
CMC muaj zog dej solubility thiab zoo kub thiab ntsev tsis kam, uas tso cai rau nws ua hauj lwm ruaj khov nyob rau hauv txawv geological tej yam kev mob. Nws zoo heev tshuaj stability thiab lubrication zog txo ntau yam teeb meem los ntawm instability ntawm drilling kua thaum lub sij hawm drilling txheej txheem, xws li av nkos los nag, roj khiav, thiab lwm yam.
Txo cov kua dej los ntawm cov av nkos
Los ntawm kev sib koom ua ke nrog lwm cov khoom, CMC tuaj yeem txo cov lim dej tsis zoo ntawm cov dej drilling, yog li tiv thaiv cov dej nkag mus rau hauv cov txheej txheem hauv av, txo kev puas tsuaj rau cov pob zeb ib puag ncig, tiv thaiv phab ntsa zoo, thiab yog li kev txhim kho drilling efficiency.
2. Qhov tshwj xeeb cuam tshuam ntawm CMC ntawm kev ua haujlwm drilling
Txhim kho qhov kev ua tau zoo ntawm cov dej drilling
Thaum lub sij hawm drilling txheej txheem, kev sib txhuam ntawm lub laum me ntsis thiab tsim yuav tsim ib tug loj npaum li cas ntawm cuttings. Yog tias lawv tsis tuaj yeem raug tshem tawm raws sijhawm, nws yuav ua rau muaj kev cuam tshuam rau kev ua haujlwm drilling. CMC txhim kho qhov kev ncua thiab nqa lub peev xwm ntawm cov dej drilling, uas tuaj yeem nqa cov kev txiav tawm ntawm lub qhov dej kom zoo kom huv si ntawm lub qhov dej. Qhov kev ua haujlwm no tseem ceeb tshwj xeeb tshaj yog rau cov hom dej sib sib zog nqus xws li qhov dej tob, qhov dej tob tob, thiab cov qhov dej kab rov tav. Nws tuaj yeem zam tau cov teeb meem zoo xws li lub qhov dej txhaws thiab me ntsis lo, yog li ua kom nrawm nrawm.
Txo qhov kev pheej hmoo ntawm cov ncej tawg
Hauv qee cov pob zeb mos los yog xoob xoob, ib qho ntawm cov haujlwm tseem ceeb ntawm cov dej drilling yog los tswj kev ruaj ntseg ntawm phab ntsa zoo. Raws li cov thickener, CMC tuaj yeem txhim kho qhov adhesion ntawm cov dej drilling, tso cai rau cov dej drilling los tsim cov yeeb yaj kiab tiv thaiv ntawm phab ntsa dej kom tiv thaiv phab ntsa dej los ntawm kev sib tsoo los yog cov av nkos los ntawm kev nkag mus rau hauv cov pob zeb ib puag ncig. Qhov no tsis tsuas yog txhim kho kev nyab xeeb ntawm kev ua haujlwm drilling, tab sis kuj txo qis lub sijhawm ua haujlwm los ntawm cov phab ntsa zoo tsis ruaj khov, yog li kev txhim kho drilling efficiency.
Txo qhov drilling kua poob
Thaum lub sij hawm drilling txheej txheem, drilling kua yuav nkag mus rau hauv av tsim, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas lub pob zeb muaj porosity siab los yog puas. CMC tuaj yeem tswj tau cov kua dej tsis zoo ntawm cov dej drilling thiab txo qhov poob ntawm cov kua dej hauv qhov hws thiab pob txha. Qhov no tsis tsuas yog pab txuag cov nqi ntawm cov dej drilling, tab sis kuj tseem tiv thaiv cov dej drilling los ntawm kev poob sai heev thiab cuam tshuam rau kev ua haujlwm, kom ntseeg tau tias cov dej drilling tseem ua haujlwm tau zoo.
Txhim kho drilling efficiency thiab shorten drilling voj voog
Vim tias CMC txhim khu kev ua tau zoo ntawm cov dej drilling, nws ua tau zoo dua hauv kev tu lub qhov dej, txhim kho cov phab ntsa zoo, thiab nqa cov txiav, yog li txo ntau yam teeb meem tshwm sim thaum lub sij hawm drilling txheej txheem thiab xyuas kom meej tias kev ua haujlwm drilling tuaj yeem smoother. thiab ua tau zoo. Kev ruaj ntseg thiab kev ua haujlwm ntawm kev ua haujlwm ntawm cov dej drilling ncaj qha cuam tshuam rau kev nce qib ntawm drilling. Kev siv CMC nce qhov nrawm nrawm, yog li ua kom lub voj voog drilling thiab txo cov nqi khiav lag luam tag nrho.
3. Daim ntawv thov piv txwv thiab cov txiaj ntsig zoo ntawm CMC
qhov tob tob drilling
Nyob rau hauv qhov tob tob drilling, raws li qhov drilling qhov tob nce thiab lub taub hau siab nce, qhov ruaj khov thiab kev ncua ntawm cov dej drilling yog qhov tseem ceeb tshwj xeeb. Los ntawm kev ntxiv CMC, qhov viscosity ntawm cov dej drilling tuaj yeem txhim kho, kev nqa lub peev xwm ntawm cov txiav tuaj yeem txhim kho, thiab kev ua haujlwm zoo ntawm cov dej drilling tuaj yeem ua kom ntseeg tau. Tsis tas li ntawd, CMC tuaj yeem txo cov sijhawm pov tseg los ntawm cov phab ntsa ntub dej thiab cov dej ntws tawm, txhim kho kev ua haujlwm ntawm qhov dej tob tob.
Kev kub siab thiab kev kub siab tsim drilling
Hauv kev tsim nrog qhov kub thiab txias siab, cov kua dej drilling yuav tsum muaj cov thermal stability thiab siab tsis kam. CMC tuaj yeem tsis tsuas yog ua kom cov nyhuv thickening ntawm qhov kub thiab txias, tab sis kuj tseem muaj kev ruaj ntseg zoo nyob rau hauv qhov chaw kub kub kom tsis txhob degradation ntawm drilling kua ua haujlwm. Hauv kev siv cov tswv yim, CMC txo cov kua dej poob thaum lub sij hawm drilling hauv cov formations thiab txo cov sij hawm poob los ntawm cov teeb meem dej drilling.
kab rov tav drilling
Thaum lub sij hawm drilling txheej txheem ntawm kab rov tav qhov dej, txij li qhov ruaj khov ntawm cov phab ntsa zoo thiab kev tshem tawm cov txiav yog qhov tshwj xeeb, kev siv covCMC raws li lub thickener muaj cov teebmeem tseem ceeb. CMC tuaj yeem txhim kho cov rheology ntawm cov dej drilling, pab cov dej drilling kom muaj kev ncua zoo thiab kev thauj mus los, kom cov txiav tuaj yeem raug tshem tawm hauv lub sijhawm, tsis txhob muaj teeb meem xws li daig thiab txhaws, thiab txhim kho kev ua haujlwm ntawm kab rov tav zoo drilling.
Raws li kev ua kom zoo drilling kua dej ntxiv, CMC daim ntawv thov nyob rau hauv cov txheej txheem drilling ho txhim kho drilling efficiency. Los ntawm kev txhim kho cov viscosity, stability thiab rheological zog ntawm drilling kua, CMC plays lub luag hauj lwm tseem ceeb hauv kev tu lub qhov dej, txo cov phab ntsa zoo, tswj cov dej poob, thiab nce drilling ceev. Nrog rau kev txhim kho txuas ntxiv ntawm kev siv tshuab drilling, CMC muaj cov ntawv thov dav dav hauv ntau qhov chaw ib puag ncig thiab yuav ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm drilling yav tom ntej.
