I-PAC-LV, PAC-Hv, PAC R, Izinto Zokumba Kawoyela

I-Polyanionic cellulose (PAC) ivamise ukuhlukaniswa ngamamaki ahlukene ngokusekelwe esisindweni samangqamuzana ayo, izinga lokushintshwa, nezinye izici. Nakhu ukuhlukaniswa kwezinye izinhlobo ezijwayelekile ze-PAC ezisetshenziswa embonini yokumba uwoyela:

1. I-PAC-LV (I-Viscosity Ephansi):
   • I-PAC-LV iyibanga eliphansi le-viscosity ye-polyanionic cellulose esetshenziswa oketshezini lokumba olusekelwe emanzini.
   • Ibonakala nge-viscosity yayo ephansi uma iqhathaniswa namanye amabanga e-PAC.
   • I-PAC-LV ivamise ukusetshenziswa lapho ukulawulwa kwe-viscosity okumaphakathi nokulawulwa kokulahlekelwa uketshezi kuyadingeka emisebenzini yokumba.
2. I-PAC-HV (I-Viscosity ephezulu):
   • I-PAC-HV iyibanga eliphakeme le-viscosity ye-polyanionic cellulose esetshenziselwa ukuzuza i-viscosity ephakeme kuketshezi lokumba olusekelwe emanzini.
   • Ihlinzeka ngezakhiwo ezinhle kakhulu ze-rheological kanye nokulawulwa kokulahlekelwa uketshezi, okuyenza ifaneleke izimo zokumba eziyinselele lapho ukumiswa okwengeziwe kokuqinile kuyadingeka.
3. I-PAC R (Ejwayelekile):
   • I-PAC R, noma i-PAC yebanga elijwayelekile, iyibanga elimaphakathi nebanga le-viscosity ye-polyanionic cellulose.
   • Ihlinzeka nge-viscosifying elinganiselayo kanye nezindawo zokulawula ukulahlekelwa kwamanzi, okwenza ifaneleke uhla olubanzi lwezinhlelo zokusebenza zokumba lapho i-viscosity emaphakathi kanye nokulawulwa kokulahlekelwa uketshezi kuyadingeka.

Lawa mabanga ahlukene e-PAC asetshenziswa oketshezini lokumba uwoyela ukuze kuzuzwe i-viscosity ethize, i-rheology, neziqondiso zokulawula ukulahlekelwa uketshezi ngokusekelwe ezimeni zokumba, izici zokubunjwa, kanye nezidingo zokuzinza kwe-wellbore.

Emisebenzini yokumba uwoyela, i-PAC isetshenziswa njengesengezo esibalulekile kuketshezi lokumba olusekelwe emanzini ukuze:

• Lawula i-viscosity kanye ne-rheology ukuze uthuthukise ukusebenza kokumba futhi uvimbele ukungazinzi kwe-wellbore.
• Nciphisa ukulahlekelwa uketshezi ekubunjweni, unciphise umonakalo wokwakheka futhi uthuthukise ukukhiqiza kahle.
• Misa ama-cuttings abhoboziwe kanye nezinto eziqinile, okwenza kube lula ukususwa kwazo emthonjeni.
• Nikeza ukuthambisa futhi unciphise ukungqubuzana phakathi kwentambo yokubhoboza nodonga lomthombo.

Sekukonke, i-PAC idlala indima ebalulekile njenge-viscosifier kanye ne-ejenti yokulawula ukulahlekelwa uketshezi kuketshezi lokumba olusekelwe emanzini, okunikela emisebenzini yokumba ephumelelayo nephumelelayo embonini kawoyela negesi.
