Polyanionic cellulose LV HV

I-Polyanionic cellulose (PAC) i-polymer encibilika emanzini etholakala ku-cellulose.Isetshenziswa kabanzi embonini kawoyela negesi njengesengezo se-drilling fluid, lapho isetshenziselwa ukulawula ukulahlekelwa uketshezi, ukwandisa i-viscosity, kanye nokwenza ngcono ukuvinjelwa kwe-shale.I-PAC itholakala emabangeni ahlukene, ngamazinga ahlukene okushintshanisa kanye nesisindo samangqamuzana.Amabanga amabili ajwayelekile e-PAC i-viscosity ephansi (LV) kanye ne-viscosity ephezulu (HV) PAC.

I-PAC LV inesisindo esiphansi samangqamuzana kanye nezinga eliphansi lokushintshwa.Isetshenziswa njenge-ejenti yokulawula ukuhlunga futhi njenge-modifier ye-rheology emanzini okumba.I-LV-PAC inokuncibilika okuhle emanzini futhi iyasebenza ezindaweni eziphansi.Ibuye isetshenziswe njenge-viscosifier kuma-slurries kasimende nanjenge-stabilizer kuma-emulsions.

I-PAC HV, ngakolunye uhlangothi, inesisindo semolekyuli ephakeme kanye nezinga eliphakeme lokushintsha kune-LV-PAC.Isetshenziswa njenge-viscosifier eyinhloko kanye ne-ejenti yokulawula ukulahlekelwa uketshezi emanzini okumba.I-HV-PAC ingasetshenziswa futhi njenge-viscosifier yesibili ngokuhlanganiswa namanye ama-polymer.Iyakwazi ukubekezelela usawoti kanye nezinga lokushisa okuphezulu, futhi iyasebenza ekugxilweni okuphezulu.

Kokubili i-LV-PAC ne-HV-PAC ziyi-polyanionic, okusho ukuthi zinezindleko ezingezinhle.Lokhu kukhokhiswa kubenza baphumelele ekulawuleni ukulahlekelwa uketshezi ngokwenza ikhekhe lokuhlunga emthonjeni.Ukushaja okungeyikho kubenza baphumelele ekuvimbeleni ukugeleza kwe-shale nokuhlakazeka.I-PAC ingaphinda ithuthukise ukuzinza kwe-wellbore ngokuvimbela ukufuduka kwezinhlayiya zenhlawulo nezinhlayiya zobumba.

Sengiphetha, i-polyanionic cellulose (PAC) iyi-polymer eguquguqukayo esetshenziswa embonini kawoyela negesi njengesengezo soketshezi lokumba.I-LV-PAC ne-HV-PAC amamaki amabili ajwayelekile e-PAC asetshenziselwa izinjongo ezihlukene.I-LV-PAC isetshenziswa njenge-ejenti yokulawula ukuhlunga nanjenge-rheology modifier, kuyilapho i-HV-PAC isetshenziswa njenge-viscosifier eyinhloko kanye ne-ejenti yokulawula ukulahlekelwa uketshezi.Womabili amamaki e-PAC angama-polyanionic futhi ayasebenza ekulawuleni ukulahlekelwa uketshezi futhi avimbele ukugeleza kwe-shale nokuhlakazeka.
