Polyanionic cellulose (PAC) bụ polymer soluble mmiri nke a na-ejikarị na ụlọ ọrụ mmanụ ala dị ka ihe mgbakwunye mmiri mmiri.Ọ bụ ihe nrụpụta polyanionic nke cellulose, nke a na-emepụta site na mgbanwe kemịkalụ nke cellulose na carboxymethyl.PAC nwere ihe ndị mara mma dị ka oke mmiri solubility, nkwụsi ike nke okpomọkụ, na nguzogide hydrolysis.Ngwongwo ndị a na-eme PAC ka ọ bụrụ ihe mgbakwunye dị mma maka sistemu mmiri mmiri na nyocha na mmepụta mmanụ ala.
Ngwa nke PAC na mkpọ mmanụ bụ tumadi n'ihi ikike ya ịchịkwa viscosity na nchacha nke mmiri mmiri.Njikwa viscosity bụ ihe dị mkpa na-arụ ọrụ ịkụ ala ka ọ na-emetụta arụmọrụ na nchekwa.Ojiji nke PAC na-enyere aka mee ka viscosity nke mmiri na-egwupụta ihe na-eme ka ọ dị ike, nke dị oke mkpa maka ịnọgide na-enwe ihe ndị na-asọpụta nke mmiri mmiri na-asọpụta.A na-achịkwa viscosity nke mmiri mkpọpu mmiri site na ntinye nke PAC ejiri mee ihe yana ịdị arọ molekụla nke polymer.Ngwakọta PAC na-arụ ọrụ dị ka ihe na-agba agba, ma ọ bụ viscosifier, n'ihi na ọ na-eme ka viscosity nke mmiri na-egwupụta ihe.Viscosity nke mmiri mkpọpu na-adabere na ntinye PAC, ogo nnọchi na ịdị arọ molekụla.
Njikwa nzacha bụ ihe ọzọ dị oke mkpa n'ịrụ ọrụ olulu mmiri.Arụ ọrụ nzacha metụtara ọnụego nke mmiri na-abanye na mgbidi olulu mmiri n'oge a na-egwupụta ihe.Iji PAC na-enyere aka melite njikwa nzacha ma belata ntinye mmiri mmiri.Ntinye mmiri mmiri nwere ike ibute mfu nke mgbasa ozi, mmebi nguzobe na mbelata arụmọrụ mkpọpu.Ịgbakwunye PAC na mmiri mmiri na-egwupụta ihe na-emepụta ihe dị ka gel nke na-eme ka achicha nzacha na mgbidi olulu mmiri.Achịcha nzacha a na-ebelata ntinye mmiri, na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe nke olulu mmiri na ibelata ihe ize ndụ nke mmebi nhazi.
A na-ejikwa PAC na-emeziwanye ihe mkpochapụ shale nke mmiri mmiri.Mbelata nke ns bụ ikike nke mmiri na-egwupụta ihe iji gbochie shale na-emeghachi omume site na mmiri mmiri na ọzịza.Mmiri mmiri na mgbasawanye nke shale reactive nwere ike ibute nsogbu dị ka enweghị isi nke ọma, ọkpọkọ rapaara, na mgbasa ozi na-efunahụ ya.Ịtinye PAC na mmiri mmiri na-egwupụta ihe na-emepụta ihe mgbochi n'etiti shale na mmiri mmiri.Ihe mgbochi a na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe nke mgbidi olulu mmiri site na ibelata hydration na ọzịza nke shale.
Ngwa ọzọ nke PAC na mkpọpu mmanụ bụ ihe mgbakwunye mbelata mbelata mmiri.Ọnwụ filtration na-ezo aka na mfu nke mmiri mmiri na-egwupụta ihe na-abanye na nhazi n'oge a na-egwupụta ihe.Ọnwụ a nwere ike ibute mmebi nguzobe, mgbasa ozi na-efunahụ yana ibelata arụmọrụ mkpọpu.Ojiji nke PAC na-enyere aka belata mfu mmiri site na ịmepụta achicha nzacha na mgbidi olulu mmiri nke na-egbochi mmiri na-asọba na nhazi ahụ.Mbelata nke mmiri mmiri na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe nke ọma ma na-eme ka ọ dị mma igwu mmiri.
A nwekwara ike iji PAC mee ka nkwụsi ike nke olulu mmiri mmiri mmiri.Nkwụsi ike nke Wellbore na-ezo aka n'ikike nke igwu mmiri iji kwado nkwụsi ike nke olulu mmiri mgbe a na-egwupụta ihe.Ojiji nke PAC na-enyere aka mee ka mgbidi olulu mmiri guzosie ike site n'ịme achicha nzacha na mgbidi olulu mmiri.Achịcha nzacha a na-ebelata ntinye mmiri n'ime mgbidi ma belata ihe ize ndụ nke enweghị isi nke ọma.
Iji polyanionic cellulose na-egwupụta mmanụ na-enye ọtụtụ uru.A na-eji PAC iji chịkwaa viscosity na nzacha arụmọrụ nke mmiri mkpọ mmiri, kwalite ọrụ mgbochi shale, belata nzacha filtration, ma melite nkwụsi ike nke ọma.Iji PAC na-egwupụta mmanụ na-enyere aka ịbawanye arụmọrụ ma na-ebelata ihe ize ndụ nke mmebi nhazi, mgbasa ozi na-efunahụ na enweghị ntụkwasị obi nke ọma.Ya mere, ojiji nke PAC dị oke mkpa maka ịga nke ọma nke ịkụ ala na mmepụta mmanụ.
