Roj Drilling Fluid Polyanionic Cellulose Polymer PAC-LV

Polyanionic cellulose low viscosity (PAC-LV) yog ib qho tseem ceeb polymer additive nyob rau hauv cov roj drilling kua formulations. Ntawm no yog cov ncauj lus kom ntxaws txog nws lub luag haujlwm thiab qhov tseem ceeb:

1. viscosity Control: PAC-LV ua lub viscosifier hauv cov roj drilling kua, txhim kho lawv lub peev xwm los tshem tawm thiab thauj cov khib nyiab thiab txiav mus rau saum npoo. Txawm hais tias nws cov viscosity tsawg piv rau lwm qib PAC, PAC-LV tseem ua rau muaj kev nce ntxiv viscosity tag nrho ntawm cov dej drilling, pab hauv lub qhov ntxuav thiab tag nrho cov drilling efficiency.
2. Fluid Loss Control: PAC-LV pab tswj cov kua dej los ntawm kev tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa borehole. Qhov no txo ​​qhov poob ntawm cov dej drilling rau hauv kev tsim, tswj kev ruaj ntseg zoo, thiab tiv thaiv qhov sib txawv ntawm qhov sib txawv thiab tsim kev puas tsuaj.
3. Kev Hloov Kho Rheology: PAC-LV cuam tshuam rau cov khoom siv rheological ntawm cov kua dej drilling, ua kom zoo rau kev ncua ntawm cov khib nyiab thiab txo qis. Nws txhim kho cov kua muaj peev xwm nqa thiab thauj cov drilled cuttings, txhim kho lub qhov ntxuav thiab txo qhov kev pheej hmoo ntawm cov teeb meem ntawm cov yeeb nkab.
4. Temperature Stability: PAC-LV nthuav qhia zoo thermal stability, tswj nws cov yam ntxwv ntawm kev ua tau zoo tshaj qhov kub ntawm ntau yam uas tau ntsib hauv kev ua haujlwm drilling. Qhov no ua kom muaj kev ua tau zoo ntawm cov dej drilling hauv ob qho tib si kub-kub thiab qis-kub ib puag ncig.
5. Salinity Compatibility: PAC-LV qhia tau tias muaj kev sib raug zoo nrog cov ntsev ntau ntau thiab cov brine feem ntau ntsib hauv thaj chaw oilfield. Nws tuav nws txoj kev ua tau zoo nyob rau hauv ntau yam dej qab ntsev, ua kom ntseeg tau qhov kev ua tau zoo ntawm cov kua dej drilling hauv kev sib txawv thiab cov reservoirs.
6. Environmental Considerations: PAC-LV yog muab los ntawm cov nroj tsuag txuas ntxiv dua tshiab thiab yog biodegradable, ua rau nws tus phooj ywg ib puag ncig. Nws siv nyob rau hauv cov dej drilling pab txo qhov cuam tshuam ib puag ncig thaum ua kom muaj kev ua haujlwm zoo drilling.
7. Formulation Flexibility: PAC-LV muaj nyob rau hauv ntau qib thiab cov kev qhia tshwj xeeb kom tau raws li cov kev xav tau ntawm cov dej drilling. Nws versatility tso cai rau formulation yooj, ua rau kev cai-tailored drilling kua tshuab los daws tej yam kev mob zoo thiab cov teeb meem.

Hauv cov ntsiab lus, polyanionic cellulose low viscosity (PAC-LV) plays lub luag haujlwm tseem ceeb hauv cov roj drilling kua formulations los ntawm kev muab viscosity tswj, kua poob tswj, rheology hloov kho, thiab ib puag ncig compatibility. Kev siv nws ua rau muaj txiaj ntsig zoo thiab ua tiav kev ua haujlwm drilling los ntawm kev tswj xyuas qhov chaw zoo, txhim kho qhov tu, thiab txo qhov tsim kev puas tsuaj.
