I-Hydroxyethyl Cellulose kuFluid Fracturing Emgodini Kawoyela

I-Hydroxyethyl cellulose (HEC) i-polymer encibilika emanzini evame ukusetshenziswa embonini kawoyela negesi njengento ejiyayo kanye ne-viscosifier kuketshezi oluqhekekayo. Uketshezi lwe-Fracturing lusetshenziswa ekuqhekekeni kwe-hydraulic, indlela esetshenziselwa ukukhipha uwoyela negesi ekwakhekeni kwamatshe e-shale.

I-HEC yengezwe ku-fracturing fluid ukuze kwandiswe i-viscosity yayo, okusiza ukuthwala ama-proppants (izinhlayiya ezincane ezifana nesihlabathi noma izinto ze-ceramic) ekuqhekekeni okudalwe edwaleni le-shale. Ama-propants asiza ukuvula ama-fractures, okuvumela uwoyela negesi ukuthi kugeleze kalula ngaphandle kokubunjwa futhi ungene emthonjeni.

I-HEC ikhethwa ngaphezu kwezinye izinhlobo zama-polymers ngoba izinzile emazingeni okushisa aphezulu kanye nezingcindezi, ezihlangabezana nazo ngesikhathi senqubo ye-hydraulic fracturing. Futhi inokuhambisana okuhle namanye amakhemikhali avame ukusetshenziswa ekuqhekekeni koketshezi.

I-HEC ibhekwa njengesengezo esiphephile uma kuqhathaniswa noketshezi oluqhekekayo, njengoba ingenabo ubuthi futhi ibola. Kodwa-ke, njenganoma iyiphi ikhemikhali, kufanele iphathwe futhi ilahlwe ngendlela efanele ukuze kugwenywe noma yimiphi imithelela engemihle endaweni ezungezile.
