I-Hydroxyethyl Cellulose kwiFluid Fracturing kwi-Oil Drilling

I-Hydroxyethyl cellulose (HEC) yipolima enyibilikayo emanzini esetyenziswa ngokuqhelekileyo kwishishini leoli kunye negesi njenge-thickener kunye ne-viscosifier kwi-fracturing fluids. I-fracturing fluids isetyenziswa kwi-hydraulic fracturing, ubuchule obusetyenziselwa ukukhupha i-oyile kunye negesi kulwakhiwo lwamatye e-shale.

I-HEC yongezwa kwi-fracturing fluid ukwandisa i-viscosity yayo, enceda ukuthwala i-proppants (iincinci ezincinci ezifana nesanti okanye izinto ze-ceramic) kwiifracture ezenziwe kwi-rock shale. Iipropathi zinceda ukuvula iifractures, ukuvumela ioli kunye negesi ukuba ihambe ngokulula ngaphandle kokubunjwa kunye nomthombo.

I-HEC ikhethwa ngaphezu kwezinye iintlobo zeepolymers ngenxa yokuba izinzile kumaqondo aphezulu kunye noxinzelelo, oludibana nayo ngexesha lenkqubo ye-hydraulic fracturing. Ikwanazo nokuhambelana kakuhle nezinye iikhemikhali ezisetyenziswa ngokuqhelekileyo kulwelo oluqhekezayo.

I-HEC ithathwa njengento eyongezelelweyo ekhuselekileyo kwi-fracturing fluids, njengoko ayinayo ityhefu kwaye i-biodegradable. Nangona kunjalo, njengayo nayiphi na imichiza, kufuneka iphathwe kwaye ilahlwe ngokufanelekileyo ukuthintela naziphi na iimpembelelo ezingalunganga kokusingqongileyo.
