Ukusetyenziswa kweSelulosi yeHydroxyethyl kwi-Oilfield Drilling

I-Hydroxyethyl cellulose (HEC) yipolymer enyibilikayo emanzini esetyenziswa kakhulu kwishishini leoli kunye negesi, ngakumbi kwimisebenzi yokomba.I-HEC isetyenziselwa ukugrumba ulwelo ukubonelela ngolawulo lwe-rheological kunye nokuthintela ukulahleka kolwelo.Oku kulandelayo zezinye zezicelo ezithile ze-HEC kwindawo yokomba yeoli:

1. Ulawulo lwe-Rheology: I-HEC isetyenziselwa ukulawula i-rheology yokucoca ulwelo.Ukongezwa kwe-HEC kwandisa i-viscosity ye-drilling fluid, enceda ukumisa i-drill cuttings kunye nokukhusela ukuhlalisa.I-viscosity ye-drilling fluid inokulungiswa ngokutshintsha ukugxininiswa kwe-HEC kumanzi.
2. UThintelo lokuLahleka kolwelo: I-HEC isetyenziswa njengesongezo sokulahleka kolwelo kulwelo lokomba.Xa ifakwe kwi-drilling fluid, i-HEC yenza ifilimu encinci kwiindonga ze-wellbore, ezinceda ukuthintela ukulahlekelwa kwe-drilling fluid ekubunjweni.
3. Ukunqunyanyiswa kwee-Solids: I-HEC yi-arhente yokumisa esebenzayo kumasuntswana aqinileyo kwi-drilling fluids.Ukongezwa kwe-HEC kunceda ukugcina izinto eziqinileyo ekumisweni, zithintele ukuba zingahlali phantsi kwe-wellbore.
4. Ulawulo lokucoca: I-HEC isetyenziswe njenge-arhente yokulawula ukuhluza kwi-drilling fluids.Ukongezwa kwe-HEC kunceda ukulawula izinga apho i-drilling fluid ihluza ekubunjweni, ukukhusela ukulahlekelwa kwexabiso elixabisekileyo lokugaya.

Isishwankathelo, i-Hydroxyethyl cellulose (HEC) idlala indima ebalulekileyo kwishishini leoli kunye negesi njenge-drilling fluid additive, ukubonelela ngolawulo lwe-rheological, ukuthintela ukulahlekelwa kwamanzi, ukumiswa kwezinto eziqinileyo, kunye nokulawulwa kokucoca.
