PAC-LV, PAC-Hv, PAC R, Cov Khoom Siv Rau Kev Tshawb Fawb Roj

Polyanionic cellulose (PAC) feem ntau yog muab faib ua ntau qib raws li nws qhov hnyav molecular, qib kev hloov pauv, thiab lwm yam khoom. Nov yog kev faib tawm ntawm qee hom PAC uas siv hauv kev lag luam drilling roj:

1. PAC-LV (Qis Viscosity):
   • PAC-LV yog qib viscosity qis ntawm polyanionic cellulose siv rau hauv cov kua dej drilling.
   • Nws yog tus cwj pwm los ntawm nws cov viscosity qis dua piv rau lwm cov qib PAC.
   • PAC-LV feem ntau yog siv thaum xav tau kev tswj hwm qhov viscosity nruab nrab thiab kev tswj hwm kev poob kua hauv kev ua haujlwm drilling.
2. PAC-HV (Viscosity Siab):
   • PAC-HV yog qib viscosity siab ntawm polyanionic cellulose siv rau kev ua tiav viscosity siab dua hauv cov kua dej drilling.
   • Nws muab cov khoom zoo heev rheological thiab tswj kev poob kua, ua rau nws haum rau cov xwm txheej drilling nyuaj uas xav tau kev ncua ntxiv ntawm cov khoom khov.
3. PAC R (Ib txwm):
   • PAC R, lossis qib PAC ib txwm muaj, yog qib viscosity nruab nrab ntawm polyanionic cellulose.
   • Nws muaj cov yam ntxwv sib npaug ntawm viscosifying thiab kua poob tswj, ua rau nws haum rau ntau yam kev siv drilling qhov twg xav tau kev tswj hwm viscosity thiab kua poob nruab nrab.

Cov qib sib txawv ntawm PAC no yog siv rau hauv cov kua roj drilling kom ua tiav cov hom phiaj tshwj xeeb viscosity, rheology, thiab cov kua dej poob tswj raws li cov xwm txheej drilling, cov yam ntxwv ntawm kev tsim, thiab cov kev cai ruaj khov ntawm lub qhov dej.

Hauv kev ua haujlwm drilling roj, PAC yog siv ua ib qho tseem ceeb ntxiv rau hauv cov kua dej drilling rau:

• Tswj cov viscosity thiab rheology kom zoo dua qhov kev ua tau zoo ntawm qhov drilling thiab tiv thaiv kom tsis txhob muaj qhov tsis ruaj khov ntawm lub qhov dej.
• Txo cov kua dej poob rau hauv qhov tsim, txo cov kev puas tsuaj ntawm qhov tsim thiab txhim kho kev tsim khoom zoo.
• Tshem cov txiav thiab cov khoom khov uas tau khawb, ua kom yooj yim tshem tawm ntawm lub qhov dej.
• Muab cov roj nplua nyeem thiab txo qhov kev sib txhuam ntawm txoj hlua khawb thiab phab ntsa qhov dej.

Zuag qhia tag nrho, PAC ua lub luag haujlwm tseem ceeb ua tus neeg sawv cev viscosifier thiab tus neeg sawv cev tswj kev poob kua hauv cov kua dej drilling, pab txhawb rau kev ua haujlwm drilling zoo thiab ua tiav hauv kev lag luam roj thiab roj av.
