Polyanionic cellulose hauv roj drilling kua

Polyanionic cellulose (PAC) yog siv dav hauv cov roj drilling kua rau nws cov khoom siv hluav taws xob thiab muaj peev xwm los tswj cov kua dej. Nov yog qee qhov haujlwm tseem ceeb thiab cov txiaj ntsig ntawm PAC hauv roj drilling kua:

1. Kev tswj cov dej: PAC yog qhov ua tau zoo hauv kev tswj cov kua dej thaum lub sijhawm. Nws tsim cov lim lim nyias, kev siv lub lim lim dej ntawm lub hnab borehole, txo qhov poob ntawm cov kua drilling mus rau hauv cov forous. Qhov no yuav pab tswj kom muaj kev ruaj khov ruaj khov, tiv thaiv kev tsim kev puas tsuaj, thiab txhim kho cov kev ua kom haum.
2. Rheology hloov kho: PAC ua raws li kev kho siab rheology, muaj kev cuam tshuam rau cov viscosity thiab flow cov khoom ntawm drilling kua. Nws pab txhawm rau tswj cov qib viscosity, txhim kho kev raug tshem tawm ntawm cov khib nyiab, thiab pab txhawb kev tshem tawm ntawm cov haujlwm ntawm qhov chaw nkaum. PAC kuj tseem txhim kho cov kua ruaj khov raws li sib txawv kub thiab cov peev txheej siab tau tshwm sim thaum lub tshuab khiav.
3. Txhim kho qhov qhov rooj ntxuav: los ntawm kev txhim kho cov khoom raug ncua ntawm cov kua dej drilling, PAC txhawb nqa qhov kev ntxuav kom zoo los ntawm kev nqa cov txiav txiav kom ntev. Qhov no pab tiv thaiv clogging ntawm qhov chaw nyob, txo qhov kev pheej hmoo ntawm cov yeeb nkab yeeb, thiab ua kom nruj kev ua haujlwm du.
4. Qhov kub qhuav: PAC cov khoom pov puag zoo ua tau zoo tshaj plaws, tswj nws qhov kev ua tau zoo thiab ua tau zoo tshaj li ntau yam kub tau ntsib hauv kev ua haujlwm drooring. Qhov no ua rau nws haum rau siv nyob rau hauv ob qho kev cai thiab kev ntsuas kub kub.
5. Kev sib xyaw nrog lwm cov tshuaj ntxiv ntxiv: PAC yog sib haum ntau txoj kev sib tw ntawm cov kua dej ntxiv, suav nrog cov polymers, clays, thiab ntsev. Nws tuaj yeem yooj yim incorporated rau ntau cov kua dej tsis muaj kev tsis zoo ntawm cov kua lossis ua tau zoo.
6. Ib puag ncig cov kev txiav txim siab: PAC yog ib puag ncig ib puag ncig thiab biodegradable, ua rau nws xaiv qhov kev xaiv txaus rau cov haujlwm tsis sib haum. Nws ua raws nrog kev cai tswj hwm thiab pab txo qis cov kev cuam tshuam ib puag ncig ntawm kev ua ub no.
7. Tus nqi-txiaj ntsig: PAC muaj cov roj uas siv tau cov roj uas siv tau zoo thiab siv hluav taws xob ntau dua piv rau lwm cov kev sib ntxiv. Nws cov kev ua tau zoo tso cai rau kev txo qis qis, txo cov khib nyiab, thiab tag nrho cov nqi txuag tau hauv cov kua dej drilling.

Polyanionic cellulose (PAC) ua lub luag haujlwm tseem ceeb hauv kev tswj cov roj roj, kev sib txawv nrog lwm cov kev sib ntxiv, kev ua raws li ib puag ncig, thiab kev ua kom zoo rau ib puag ncig. Nws cov khoom muaj ntau yam ua rau nws tseem ceeb ntxiv rau kev ua tiav kev ua haujlwm zoo tshaj plaws thiab kev tshawb nrhiav cov haujlwm thiab kev ua haujlwm ntau dua.
