Iziphumo zeHydroxyethyl Cellulose kwi-Oilfields

I-Hydroxyethyl Cellulose (HEC) i-polymer e-soluble yamanzi esetyenziswa ngokuqhelekileyo kwishishini leoli kunye negesi njenge-rheology modifier, i-thickener, kunye ne-stabilizer. Nazi ezinye zeempembelelo ze-HEC kwiindawo zeoli:

1. Ulawulo lwe-Viscosity: I-HEC isetyenziselwa ukulawula i-viscosity yokugaya amanzi kunye ne-samente slurries kwiindawo zeoli. Inceda ukugcina i-viscosity ezinzileyo phantsi kweemeko ezahlukeneyo, ezifana nobushushu kunye nokutshintsha koxinzelelo.
2. Ukulawulwa kokucoca: I-HEC inokunciphisa izinga lokulahleka kwamanzi kwi-drilling fluids kunye ne-samente slurries, ephucula iimpawu zabo zokulawula ukuhluza. Oku kunceda ukuthintela ukubunjwa kwamaqebengwana odaka angagxumekiyo kunye nokunciphisa umngcipheko wokuxinga kombhobho ngexesha lomsebenzi wokomba.
3. I-Shear thinning: I-HEC ibonisa ukuziphatha kwe-shear-thinning, oku kuthetha ukuba i-viscosity yayo iyancipha phantsi koxinzelelo lwe-shear. Le propati ingaba luncedo kwizicelo ze-oilfield apho i-viscosity ephantsi ifunekayo ngexesha lokupompa kodwa i-viscosity ephezulu ifunwa kwi-wellbore.
4. Ukuzinza kwe-Fluid: I-HEC inceda ukuzinzisa ulwelo lokugaya kunye ne-cement slurry ngokuthintela ukuhlalisa kunye nokujikeleza kwezinto eziqinileyo ezimisiwe.
5. Ukuhambelana nokusingqongileyo: I-HEC inobuhlobo nokusingqongileyo kwaye ayibangeli monakalo kwi-ikhosistim. Ayinatyhefu kwaye iyabola, iyenza ibe lukhetho olukhuselekileyo lokusetyenziswa kwiindawo zeoyile.
6. Ukuhambelana nezinye izongezo: I-HEC iyahambelana noluhlu olubanzi lwezinye izongezo ezisetyenziswa kwishishini leoli kunye negesi, kubandakanywa udaka lwe-drilling, i-brines, kunye ne-samente slurries. Ingasetyenziselwa ukudibanisa nezinye iipolymers, ezifana ne-xanthan gum, ukuphucula ukusebenza kwe-drilling fluids kunye ne-cement slurries.

Ngokubanzi, iimpembelelo ze-HEC kwiindawo ze-oyile zenza ukuba ibe yongezelelo oluxabisekileyo ekuphuculeni iipropathi zokugaya ulwelo kunye ne-samente slurries. Ulawulo lwayo lwe-viscosity, ulawulo lokuhluza, i-shear thinning behavior, ukuzinza kwamanzi, ukuhambelana nokusingqongileyo, kunye nokuhambelana nezinye izongezo kuyenza ibe yinto ebalulekileyo kwishishini leoli kunye negesi.
