I-PAC-LV, i-PAC-Hv, i-PAC R, Izinto Zokubhoboza Uwoyela

I-polyanionic cellulose (PAC) ivame ukuhlukaniswa ngamamaki ahlukene ngokusekelwe esisindweni sayo sama-molecule, izinga lokushintshaniswa, kanye nezinye izakhiwo. Nansi incazelo yezinhlobo ezithile ezivamile ze-PAC ezisetshenziswa embonini yokumba uwoyela:

1. I-PAC-LV (Ukuqina Okuphansi):
   • I-PAC-LV iyizinga eliphansi le-viscosity ye-polyanionic cellulose esetshenziswa oketshezini lokubhoboza olusekelwe emanzini.
   • Ibonakala nge-viscosity yayo ephansi uma iqhathaniswa nezinye izinhlobo ze-PAC.
   • I-PAC-LV ivame ukusetshenziswa lapho kudingeka ukulawulwa kwe-viscosity okulinganiselwe kanye nokulawulwa kokulahlekelwa uketshezi emisebenzini yokubhoboza.
2. I-PAC-HV (Ukuqina Okuphezulu):
   • I-PAC-HV iyizinga eliphezulu le-viscosity le-polyanionic cellulose elisetshenziselwa ukufeza i-viscosity ephezulu emanzini okubhoboza asekelwe emanzini.
   • Inikeza izakhiwo ezinhle kakhulu ze-rheological kanye nokulawula ukulahleka koketshezi, okwenza ifanelekele izimo zokubhoboza ezinzima lapho kudingeka khona ukumiswa okwengeziwe kwezinto eziqinile.
3. I-PAC R (Ejwayelekile):
   • I-PAC R, noma i-PAC yebanga elijwayelekile, iyibanga le-viscosity eliphakathi nendawo le-polyanionic cellulose.
   • Inikeza izakhiwo zokulawula ukuqina okulinganiselwe kanye nokulahlekelwa uketshezi, okwenza ifaneleke ezinhlotsheni eziningi zezicelo zokubhoboza lapho kudingeka khona ukuqina okulinganiselwe kanye nokulawulwa kokulahlekelwa uketshezi.

Lezi zinhlobo ezahlukene ze-PAC zisetshenziswa oketshezini lokubhoboza uwoyela ukuze kufezwe imigomo ethile yokulawula ukuqina, i-rheology, kanye nokulahlekelwa uketshezi ngokusekelwe ezimweni zokubhoboza, izici zokwakheka, kanye nezidingo zokuqina kwe-wellbor.

Emisebenzini yokumba uwoyela, i-PAC isetshenziswa njengesithako esibalulekile koketshezi lokumba olusekelwe emanzini ukuze:

• Lawula i-viscosity kanye ne-rheology ukuze uthuthukise ukusebenza kokubhoboza futhi uvimbele ukungazinzi kwe-wellbore.
• Nciphisa ukulahleka koketshezi ekwakhekeni, unciphise umonakalo ekwakhekeni futhi uthuthukise umkhiqizo womthombo.
• Misa izingcezu ezibhoboziwe kanye nezinto eziqinile, okwenza kube lula ukuzisusa emgodini womthombo.
• Nikeza ukuthambisa futhi unciphise ukungqubuzana phakathi kwentambo yokubhoboza nodonga olumbozwe kahle.

Sekukonke, i-PAC idlala indima ebalulekile njenge-viscosifier kanye ne-ejenti yokulawula ukulahlekelwa uketshezi oketshezini lokubhoboza olusekelwe emanzini, okunegalelo ekusebenzeni kahle nokuphumelelayo kokubhoboza embonini kawoyela negesi.
