Imiphumela ye-Hydroxyethyl Cellulose ku-Oilfields

I-Hydroxyethyl Cellulose (HEC) i-polymer encibilika emanzini evame ukusetshenziswa embonini kawoyela negesi njenge-rheology modifier, thickener, kanye ne-stabilizer. Nansi eminye yemiphumela ye-HEC ezindaweni zikawoyela:

1. Ukulawulwa kwe-viscosity: I-HEC isetshenziselwa ukulawula i-viscosity yokumba uketshezi kanye nama-slurries kasimende ezindaweni zikawoyela. Kuyasiza ukugcina i-viscosity ezinzile ngaphansi kwezimo ezihlukahlukene, njengezinga lokushisa noshintsho lwengcindezi.
2. Ukulawulwa kokuhlunga: I-HEC inganciphisa izinga lokulahlekelwa uketshezi emanzini okumba kanye nama-slurries kasimende, okuthuthukisa izakhiwo zawo zokulawula ukuhlunga. Lokhu kusiza ukuvimbela ukwakheka kwamaqebelengwane odaka angangeni futhi kunciphisa ingozi yepayipi elinamathele ngesikhathi sokumba.
3. I-Shear thinning: I-HEC ibonisa ukuziphatha kokunciphisa i-shear, okusho ukuthi i-viscosity yayo iyancipha ngaphansi kwengcindezi yokugunda. Lesi sakhiwo singaba wusizo ekusetshenzisweni kwendawo yamafutha lapho i-viscosity ephansi idingeka ngesikhathi sokupompa kodwa i-viscosity ephezulu ifunwa emgodini womthombo.
4. Ukuzinza kwe-Fluid: I-HEC isiza ukuzinzisa uketshezi lokumba kanye nodaka lukasimende ngokuvimbela ukumisa nokugeleza kwezinto eziqinile ezimisiwe.
5. Ukuhambisana nemvelo: I-HEC ihambisana nemvelo futhi ayidali kulimaze i-ecosystem. Ayinabuthi futhi iyabola, okuyenza ibe inketho ephephile ukuthi isetshenziswe ezindaweni zikawoyela.
6. Ukuhambisana nezinye izithasiselo: I-HEC ihambisana nohlu olubanzi lwezinye izithasiselo ezisetshenziswa embonini kawoyela negesi, okuhlanganisa ukumba udaka, ama-brines, nama-slurries kasimende. Ingasetshenziswa ngokuhambisana namanye ama-polymers, njenge-xanthan gum, ukuthuthukisa ukusebenza koketshezi lokumba kanye ne-cement slurries.

Sekukonke, imiphumela ye-HEC ezindaweni zikawoyela iyenza ibe isithako esibalulekile sokuthuthukisa izakhiwo zoketshezi lokumba kanye nama-slurries usimende. Ukulawula i-viscosity yayo, ukulawulwa kokuhlunga, ukuziphatha kokugunda kwe-shear, ukuzinza koketshezi, ukuhambisana kwemvelo, nokuhambisana nezinye izithasiselo kuyenza ibe isithako esibalulekile embonini kawoyela negesi.
