Njengoba ukunaka kwezwe ekuvikeleni indawo ezungezile kuqhubeka kwanda, imboni kawoyela, njengendawo ewumgogodla yokuphakelwa kukagesi, iye yadonsa ukunakwa okukhulu ngezindaba zayo zemvelo. Kulo mongo, ukusetshenziswa nokuphathwa kwamakhemikhali kubaluleke kakhulu.I-Hydroxyethyl Cellulose (HEC), njenge-polymer encibilikayo emanzini, isetshenziswa kabanzi ezicini eziningi zemboni kawoyela ngenxa yokusebenza kwayo okuhle kakhulu kanye nezici zokuvikela imvelo, ikakhulukazi emanzini okumba, uketshezi oluqhekekayo kanye neziqinisa udaka.
Izici eziyisisekelo ze-HEC
I-HEC iyi-polymer engeyona i-ionic eyenziwe ngokushintsha i-cellulose yemvelo, enezici ezilandelayo ezibalulekile:
I-Biodegradability: I-KimaCell®HEC yenziwe ngezinto zemvelo futhi ingaboliswa ama-microorganisms, ukugwema ukunqwabelana kokungcola okuqhubekayo endaweni ezungezile.
Ubuthi obuphansi: I-HEC izinzile kusisombululo esinamanzi, inobuthi obuphansi ku-ecosystem, futhi ifanele izikhathi ezinezidingo eziphezulu zemvelo.
Ukuncibilika kwamanzi nokuqina: I-HEC ingancibilika emanzini futhi yakhe isixazululo se-viscosity ephezulu, okwenza kube kuhle kakhulu ekulungiseni i-rheology kanye nezakhiwo zokumiswa zoketshezi.
Izicelo eziyinhloko embonini kawoyela
Isicelo ku-drilling fluid
Uketshezi lokumba luyingxenye ebalulekile enqubweni yokukhipha uwoyela, futhi ukusebenza kwawo kuthinta ngokuqondile ukusebenza kahle kokubhola kanye nokuvikelwa kokwakheka. I-HEC, njenge-thickener kanye ne-fluid loss reducer, ingakwazi ukuthuthukisa ngokuphumelelayo izakhiwo ze-rheological zokubhoboza uketshezi, ngenkathi inciphisa ukungena kwamanzi ekubunjweni nokunciphisa ingozi yokulimala kokubunjwa. Uma kuqhathaniswa nama-polymers okwenziwa endabuko, i-HEC inengozi ephansi yokungcoliswa komhlabathi ozungezile namanzi angaphansi komhlaba ngenxa yobuthi bayo obuncane kanye nokuwohloka.
Isicelo ku-fracturing fluid
Ngesikhathi senqubo yokuqhekeka, i-fracturing fluid isetshenziselwa ukwandisa ukuphuka nokuthwala isihlabathi. I-HEC ingasetshenziswa njenge-thickener ye-fracturing fluid, ithuthukise i-viscosity ye-liquid ukuthuthukisa umthamo wokuthwala isihlabathi, futhi uma kunesidingo, ingahle ihlaziywe ngama-enzyme noma ama-acids ukukhulula ama-fractures nokubuyisela ukubunjwa kwe-permeability. Leli khono lokulawula ukuwohloka lisiza ukunciphisa izinsalela zamakhemikhali, ngaleyo ndlela kuncishiswe imiphumela yesikhathi eside ekubunjweni nasezinhlelweni zamanzi angaphansi komhlaba.
Isiqinisi sodaka nesivimbeli ukulahleka kwamanzi
I-HEC iphinde isetshenziswe kabanzi njenge-stabilizer yodaka kanye nokuvimbela ukulahlekelwa kwamanzi, ikakhulukazi ngaphansi kokushisa okuphezulu nezimo zokucindezela okukhulu. Ukuzinza kwayo okuhle kakhulu kanye nokuncibilika kwamanzi kunganciphisa kakhulu ukulahlekelwa kwamanzi odaka futhi kuvikele ubuqotho bokwakheka. Ngesikhathi esifanayo, njengoba i-HEC ingasetshenziswa ngokuhlanganiswa nezinye izithasiselo ezinobungani bemvelo, ukusetshenziswa kwayo kunciphisa kakhulu ukulimala kwemvelo.
Umthelela wendawo
Yehlisa ukungcoliswa kwemvelo
Izithasiselo zamakhemikhali zendabuko ezifana nezinto zokwenziwa ze-polyacrylamide ngokuvamile zine-eco-toxicity ephezulu, kuyilapho i-HEC, ngenxa yemvelaphi yayo yemvelo kanye nobuthi obuphansi, inciphisa kakhulu ubunzima bokwelashwa kwemfucuza kanye nezingozi zokungcoliswa kwemvelo lapho isetshenziswa embonini kawoyela.
Sekela intuthuko esimeme
Imvelo ye-HEC ebolayo iyenza ikwazi ukubola kancane kancane ibe yizinto ezingenabungozi emvelweni, okusiza ukufeza ukwelashwa okuluhlaza kwemfucuza yemboni kawoyela. Ukwengeza, izici zayo zokutholwa kwezinsiza ezivuselelekayo nazo zihambisana nomqondo wentuthuko esimeme yomhlaba wonke.
Yehlisa ukulimala kwemvelo kwesibili
Ukulimala kokwakhiwa kanye nezinsalela zamakhemikhali yizona zinkinga eziyinhloko zemvelo ohlelweni lokukhishwa kukawoyela. I-HEC inciphisa kakhulu ingozi yokungcoliswa kwesibili emanzini nasenhlabathini ngenkathi inciphisa umonakalo wokwakheka futhi ithuthukisa izinqubo zokubhoboza kanye ne-fracturing. Lesi sici sikwenza kube enye indlela eluhlaza kumakhemikhali endabuko.
Izinselelo nentuthuko yesikhathi esizayo
NakubaI-HECibonise izinzuzo ezibalulekile ekuvikelweni kwemvelo nokusebenza, izindleko zayo eziphakeme kanye nemikhawulo yokusebenza ngaphansi kwezimo ezibucayi (ezifana nezinga lokushisa eliphezulu, usawoti omningi, njll.) kuseyizici ezikhawulela ukukhuthazwa kwayo okusabalele. Ucwaningo lwesikhathi esizayo lungagxila ekuguqulweni kwesakhiwo se-HEC ukuze kuthuthukiswe ukumelana nosawoti kanye nokuzinza okuphezulu kwezinga lokushisa. Ukukhuthaza ukusetshenziswa kwe-HEC ngezinga elikhulu nokujwayelekile embonini kawoyela kuyisihluthulelo sokuqaphela amandla ayo okuvikela imvelo.
I-HEC idlala indima ebalulekile embonini kawoyela ngenxa yokusebenza kwayo okuhle kakhulu nezici zokuvikela imvelo. Ngokwenza ngcono ukusebenza koketshezi lokumba, uketshezi oluqhekekayo nodaka, i-KimaCell®HEC ayithuthukisi nje kuphela ukusebenza kahle kokukhipha uwoyela, kodwa futhi inciphisa kakhulu umthelela omubi endaweni ezungezile. Ngaphansi kwesimo soguquko lwamandla aluhlaza emhlabeni wonke, ukukhuthazwa nokusetyenziswa kwe-HEC kuzonikeza ukwesekwa okuqinile kwentuthuko esimeme yemboni kawoyela.
