Kev ua haujlwm siab PAC rau cov dej-raws li drilling kua

High-performance polyanionic cellulose (PAC) yog ib qho tseem ceeb additive nyob rau hauv dej-raws li drilling kua, muab ib tug ntau yam ntawm cov kev pab cuam uas txhim kho drilling efficiency, zoo bore stability, thiab tag nrho cov kev ua tau zoo.PAC yog cov dej-soluble polymer muab tau los ntawm cellulose, thiab nws siv rau hauv cov dej drilling pab tswj rheology, kua poob, thiab kev tswj pom.Nov yog qhov ua tau zoo PAC ua haujlwm li cas rau kev ua haujlwm ntawm cov dej-raws li drilling kua:

Cov yam ntxwv ntawm Kev Ua Haujlwm Siab PAC:

1. Dej Solubility: High-performance PAC yog yooj yim soluble nyob rau hauv dej, tso cai rau yooj yim sib tov thiab dispersion nyob rau hauv drilling kua systems.
2. Thickening thiab Rheology Control: PAC ua lub viscosifier hauv cov kua dej drilling, pab ua kom tiav thiab tswj tau qhov xav tau viscosity thiab rheological zog.Nws imparts shear-thinning tus cwj pwm, yooj yim pumpability thaum ncig thiab shear rov qab thaum zoo li qub.
3. Fluid Loss Control: PAC tsim ib lub ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa borehole, zoo txo ​​cov dej poob rau hauv kev tsim.Qhov no pab tswj kev ruaj ntseg zoo, tiv thaiv kev tsim kev puas tsuaj, thiab txo qis cov teeb meem kev poob qis.
4. Kub thiab Salinity Stability: High-performance PAC yog tsim los tswj nws cov kev ua tau zoo thiab ruaj khov nyob rau hauv ib tug ntau yam ntawm kub thiab salinity theem ntsib thaum drilling ua hauj lwm, nrog rau high-kub thiab high-salinity ib puag ncig.
5. Compatibility nrog Additives: PAC pom zoo compatibility nrog rau lwm yam drilling kua additives, xws li av nplaum stabilizers, lubricants, shale inhibitors, thiab hnyav hnyav.Nws tuaj yeem siv ua ke nrog ntau yam khoom ntxiv rau kev txiav cov dej drilling cov khoom rau cov xwm txheej tshwj xeeb thiab cov hom phiaj.

Cov txiaj ntsig ntawm Kev Ua Haujlwm Siab PAC hauv Cov Dej Drilling Fluids:

1. Txhim Kho Qhov Kev Tu: PAC pab tshem tawm cov tho kev txiav thiab cov khib nyiab hauv cov dej drilling, txhawb nqa kev tshem tawm ntawm lub qhov dej thiab tiv thaiv lawv los ntawm kev daws teeb meem thiab ua rau muaj teeb meem hauv qhov chaw.
2. Txhim kho Lubricity: Lub xub ntiag ntawm PAC nyob rau hauv cov dej drilling txo cov kev sib txhuam ntawm txoj hlua laum thiab lub qhov dej, txhim kho kev ua haujlwm drilling, txo lub zog thiab rub, thiab txuas ntxiv lub neej ntawm cov khoom siv drilling.
3. Stabilized Wellbore: PAC pab tiv thaiv qhov teeb meem tsis ruaj khov, xws li qhov loj me, sloughing shale, thiab kev tsim lub cev qhuav dej, los ntawm kev muab kev pom zoo tswj thiab tswj kev ruaj ntseg zoo.
4. Nce Tus Nqi Nkag: Los ntawm kev ua kom zoo dua cov dej drilling thiab txo cov kev sib txhuam tsis zoo, PAC kev ua haujlwm siab tuaj yeem ua rau kom nrawm dua qhov drilling thiab txuag lub sijhawm tag nrho hauv kev ua haujlwm drilling.
5. Environmental and Regulatory Compliance: Dej-raws li drilling kua uas muaj cov kev ua tau zoo PAC muab ib puag ncig zoo tshaj cov roj-raws li cov kua, suav nrog txo kev cuam tshuam ib puag ncig, yooj yim pov tseg, thiab ua raws li cov cai tswj kev ua haujlwm drilling.

Daim ntawv thov kev ua haujlwm siab PAC:

Kev ua tau zoo PAC yog siv ntau yam ntawm cov kua dej drilling, suav nrog:

• Dej-raws li av nkos (WBM): PAC yog ib qho tseem ceeb ntawm cov dej qab zib, dej ntsev, thiab cov av nkos uas siv rau ntau yam kev siv drilling, suav nrog kev tshawb nrhiav, tsim khoom, thiab ua tiav.
• Kab rov tav thiab kev taw qhia drilling: PAC pab tswj kev ruaj ntseg zoo thiab kev tswj xyuas hauv cov txheej txheem drilling nyuaj, xws li cov qhov dej txuas ntxiv, cov qhov dej kab rov tav, thiab cov qhov dej sib txawv heev.
• Offshore drilling: PAC yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv kev ua haujlwm ntawm ntug dej hiav txwv, qhov twg kev xav txog ib puag ncig, kev txwv cov khoom siv, thiab kev ruaj ntseg zoo yog qhov tseem ceeb.

Xaus:

High-performance polyanionic cellulose (PAC) plays lub luag hauj lwm tseem ceeb nyob rau hauv cov dej-raws li drilling kua, muab qhov tseem ceeb rheological tswj, kua tsis tswj, thiab wellbore stabilization zog.Los ntawm kev sib koom ua haujlwm siab PAC rau hauv cov kua dej drilling, cov neeg ua haujlwm tuaj yeem ua tiav kev ua haujlwm zoo dua qub, kev ruaj ntseg zoo, thiab kev ua tau zoo tag nrho, thaum kawg ua rau kev ua tiav thiab kev siv nyiaj txiag zoo.
