Polyanionic cellulose LV HV

I-Polyanionic cellulose (PAC) i-polymer e-soluble yamanzi ephuma kwi-cellulose. Isetyenziswa kakhulu kwishishini leoli kunye negesi njengesongezo solwelo lokomba, apho isetyenziselwa ukulawula ukulahleka kolwelo, ukwandisa i-viscosity, kunye nokuphucula inhibition ye-shale. I-PAC ifumaneka kumabakala ahlukeneyo, ngamaqondo ahlukeneyo okutshintsha kunye nobunzima bemolekyuli. Amanqaku amabini aqhelekileyo ePAC yi-viscosity ephantsi (LV) kunye ne-viscosity ephezulu (HV) PAC.

I-PAC LV inobunzima obuphantsi bemolekyuli kunye neqondo eliphantsi lokuthatha indawo. Isetyenziswe njenge-arhente yokulawula ukuhluza kunye ne-rheology modifier kwi-drilling fluids. I-LV-PAC inokunyibilika okulungileyo emanzini kwaye iyasebenza kwiindawo eziphantsi. Ikwasetyenziswa njenge-viscosifier kwi-sement slurries kwaye njenge-stabilizer kwi-emulsions.

I-PAC HV, kwelinye icala, inobunzima obuphezulu bemolekyuli kunye neqondo eliphezulu lokuthatha indawo kune-LV-PAC. Isetyenziswa njenge-viscosifier ephambili kunye nearhente yokulawula ukulahleka kolwelo kumanzi okomba. I-HV-PAC isenokusetyenziswa njenge-viscosifier yesibini ngokudityaniswa nezinye iipholima. Inokunyamezela ityuwa kunye nobushushu, kwaye iyasebenza kwiindawo eziphezulu.

Zombini i-LV-PAC kunye ne-HV-PAC zi-polyanionic, okuthetha ukuba zithwala intlawulo embi. Le ntlawulo ibenza basebenze ekulawuleni ilahleko yolwelo ngokwenza ikeyiki yokucoca kwiqula. Umrhumo ongalunganga uwenza ukuba asebenze ekuthinteleni i-shale hydration kunye nokusasazeka. I-PAC inokuphucula uzinzo lwe-wellbore ngokuthintela ukufuduka kwezohlwayo kunye namasuntswana odongwe.

Ukuqukumbela, i-polyanionic cellulose (PAC) i-polymer eguquguqukayo esetyenziswa kwishishini leoli kunye negesi njenge-drilling fluid additive. I-LV-PAC ne-HV-PAC ngamabakala amabini afanayo ePAC asetyenziselwa iinjongo ezahlukeneyo. I-LV-PAC isetyenziswa njenge-arhente yokulawula ukuhluza kunye ne-rheology modifier, ngelixa i-HV-PAC isetyenziswa njenge-viscosifier ephambili kunye ne-arhente yokulawula ukulahleka kwamanzi. Omabini amabanga e-PAC a-polyanionic kwaye ayasebenza ekulawuleni ukulahleka kolwelo kunye nokuthintela ukuhanjiswa kwe-shale kunye nokusasazeka.
