Ukusetshenziswa kwe-PAC ekumba uwoyela
Uhlolojikelele
I-Poly anionic cellulose, efushanisiwe ngokuthi i-PAC, iphuma e-ether cellulose encibilika emanzini ekhiqizwa ukuguqulwa kwamakhemikhali e-cellulose yemvelo, iyi-ether ye-cellulose encibilikayo ebalulekile emanzini, iyimpushana emhlophe noma ephuzi kancane, engenabuthi, ayinambitheki. Ingancibilika emanzini, inokuqina okuhle kokushisa nokumelana nosawoti, kanye nezakhiwo eziqinile zokulwa namagciwane. Uketshezi lodaka olwakhiwe ngalo mkhiqizo lunokuncipha okuhle kokulahlekelwa kwamanzi, ukuvimbela nokumelana nokushisa okuphezulu. Isetshenziswa kakhulu ekumba uwoyela, ikakhulukazi imithombo yamanzi anosawoti kanye nokumba uwoyela ogwini lolwandle.
Izici ze-PAC
Ingeka-ionic cellulose ether enokuhlanzeka okuphezulu, izinga eliphezulu lokushintsha kanye nokusatshalaliswa okufanayo kwezinto ezibambele. Ingasetshenziswa njenge-ejenti yokuqina, i-rheology modifier, i-ejenti yokunciphisa ukulahlekelwa kwamanzi nokunye.
1.Ifanele ukusetshenziswa kunoma yiluphi udaka kusuka emanzini ahlanzekile kuya emanzini anosawoti agcwele.
I-2.I-PAC ye-viscosity ephansi inganciphisa ngempumelelo ukulahlekelwa kokuhlunga futhi ingakhulisi kakhulu i-mucus yesistimu.
3.I-PAC ene-viscosity ephezulu ine-slurry ephezulu kanye nomphumela osobala wokwehlisa ukulahleka kwamanzi. Ifaneleka ngokukhethekile i-slurry yesigaba esiphansi-solid-phase kanye ne-non-solid-isigaba samanzi anosawoti.
4.Imifudlana yodaka eyenziwe nge-PAC ivimbela ubumba nokuhlakazeka kwe-shale kanye nokwanda endaweni enosawoti omningi, ngaleyo ndlela ivumela ukungcoliswa kodonga lwemithombo ukuthi kulawulwe.
5.Ukumba udaka okuhle kakhulu kanye noketshezi olusebenzayo, uketshezi oluhlakazekayo olusebenzayo.
I-PACIsicelo
1.PAC isicelo oketshezini sokumba.
I-PAC ilungele ukusetshenziswa njenge-inhibitor kanye ne-ejenti yokunciphisa ukulahleka kwamanzi. Imifudlana yodaka eyenziwe ye-PAC ivimbela ubumba nokuhlakazeka kwe-shale kanye nokuvuvukala endaweni enosawoti omningi, ngaleyo ndlela ivumela ukungcoliswa kodonga lwemithombo ukuthi kulawulwe.
2. Isicelo se-PAC oketshezini lokusebenza.
Uketshezi olusebenza kahle oluhlanganiswe ne-PAC luqinile kancane, olungavimbeli ukungena kokubunjwa okukhiqizayo ngezinto eziqinile futhi angalimazi ukwakheka kokukhiqiza; futhi ube nokulahlekelwa kwamanzi aphansi, okunciphisa amanzi angena ekubunjweni kokukhiqiza.
Ivikela ukwakheka kokukhiqiza ekulimaleni unomphela.
Yiba nekhono lokuhlanza ama-boreholes, ukugcinwa kwemigodi kuyancipha.
Inamandla okumelana nokungenwa kwamanzi nenhlabathi futhi ayivamisile ukuba namagwebu.
Ingagcinwa noma idluliselwe phakathi kwemithombo nemithombo, izindleko eziphansi kunoketshezi oluvamile olusebenza ngodaka.
3. Isicelo se-PAC oketshezini oluqhekekayo.
I-fracturing fluid eyenziwe nge-PAC inokusebenza okuhle kokuncibilika. Kulula ukuyisebenzisa, futhi inejubane elisheshayo lokwakheka kwejeli namandla aqinile okuthwala isihlabathi. Ingasetshenziswa ekwakhekeni kwengcindezi ye-osmotic ephansi, futhi umphumela wayo wokuqhekeka muhle kakhulu.
