Polyanionic Cellulose hauv Roj Drilling Fluid

Polyanionic Cellulose (PAC) yog dav siv nyob rau hauv cov roj drilling kua rau nws rheological zog thiab muaj peev xwm tswj cov kua dej. Nov yog qee qhov haujlwm tseem ceeb thiab cov txiaj ntsig ntawm PAC hauv cov roj drilling kua:

1. Fluid Poob Control: PAC muaj txiaj ntsig zoo hauv kev tswj cov kua dej thaum lub sijhawm ua haujlwm drilling. Nws tsim ib daim nyias nyias, impermeable lim ncuav mog qab zib rau ntawm phab ntsa borehole, txo qhov poob ntawm drilling kua rau hauv ntxeem tau formations. Qhov no pab tswj kev ruaj ntseg zoo, tiv thaiv kev tsim kev puas tsuaj, thiab txhim kho tag nrho cov drilling efficiency.
2. Rheology Hloov Kho: PAC ua raws li kev hloov kho rheology, cuam tshuam cov viscosity thiab ntws cov khoom ntawm cov kua dej drilling. Nws pab tswj cov qib viscosity uas xav tau, txhim kho kev ncua ntawm kev xyaum txiav, thiab ua kom yooj yim tshem tawm cov khib nyiab los ntawm lub qhov dej. PAC kuj tseem txhim kho cov kua dej ruaj khov nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias thiab lub zog siab thaum lub sij hawm drilling.
3. Txhim Kho Qhov Kev Tu Kom Zoo: Los ntawm kev txhim kho cov khoom raug tshem tawm ntawm cov dej drilling, PAC txhawb kev tu lub qhov zoo los ntawm kev nqa cov laum txiav rau saum npoo. Qhov no pab tiv thaiv clogging ntawm lub qhov dej, txo qhov kev pheej hmoo ntawm cov teeb meem ntawm cov yeeb nkab, thiab ua kom cov kev ua haujlwm zoo drilling.
4. Temperature Stability: PAC qhia txog qhov kub thiab txias zoo, tswj nws cov kev ua tau zoo thiab kev ua tau zoo ntawm ntau qhov kub thiab txias tau ntsib hauv kev ua haujlwm drilling. Qhov no ua rau nws haum rau siv nyob rau hauv ob qho tib si pa thiab high-temperature drilling ib puag ncig.
5. Compatibility nrog Lwm yam Additives: PAC yog sib xws nrog ntau yam ntawm drilling kua additives, xws li polymers, av nplaum, thiab ntsev. Nws tuaj yeem yooj yim muab tso rau hauv ntau yam kev siv cov kua dej drilling yam tsis muaj kev cuam tshuam rau cov kua dej lossis kev ua haujlwm.
6. Environmental Considerations: PAC yog ib puag ncig tus phooj ywg thiab biodegradable, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm drilling hauv thaj chaw rhiab heev. Nws ua raws li cov cai tswj hwm thiab pab txo qis ib puag ncig kev cuam tshuam ntawm kev ua haujlwm drilling.
7. Nqi-Effectiveness: PAC muaj nqi-zoo kua tsis tswj thiab hloov kho rheological piv rau lwm yam additives. Nws qhov kev ua tau zoo tso cai rau qis dua, txo cov khoom pov tseg, thiab kev txuag nqi tag nrho hauv cov kua dej drilling.

Polyanionic Cellulose (PAC) plays lub luag haujlwm tseem ceeb hauv cov roj drilling kua los ntawm kev muab cov kua dej tsis zoo, kev hloov kho rheology, txhim kho qhov tu, qhov kub thiab txias, kev sib raug zoo nrog lwm cov khoom siv ntxiv, kev ua raws li ib puag ncig, thiab kev siv nyiaj zoo. Nws cov khoom siv ntau yam ua rau nws yog ib qho tseem ceeb ntxiv rau kev ua tiav kev ua haujlwm zoo drilling thiab kev ua haujlwm zoo hauv kev tshawb nrhiav roj thiab roj thiab kev tsim khoom.
