Iziphumo zeHydroxyethyl Cellulose kwi-Oilfields

I-Hydroxyethyl cellulose (HEC) ifumana izicelo ezininzi kwishishini leoli kunye negesi, ngakumbi kwimimandla yeoli. Nazi ezinye zeziphumo kunye nokusetyenziswa kwe-HEC kwimisebenzi ye-oyile:

1. I-Drilling Fluids: I-HEC isoloko idibaniswa kwi-drilling fluids ukulawula i-viscosity kunye ne-rheology. Isebenza njenge-viscosifier, inika uzinzo kunye nokuphucula umthamo wokuthwala umbane wokugaya. Oku kunceda ukunqumamisa i-drill cuttings kunye nezinye izinto eziqinileyo, zithintele ukuba zingazinzi kwaye zibangele imiqobo kwiqula.
2. Ukulawulwa kokujikeleza okulahlekileyo: I-HEC inokunceda ukulawula ukujikeleza okulahlekileyo ngexesha lomsebenzi wokugaya ngokwenza umqobo ngokuchasene nokulahleka kwamanzi kwiifom ze-porous. Inceda ukutywina iifractures kunye nezinye iindawo ezivuzayo ekubunjweni, ukunciphisa umngcipheko wokulahleka kokujikeleza kunye nokungazinzi kakuhle.
3. I-Wellbore Cleanup: I-HEC inokusetyenziswa njengenxalenye kumanzi okucoca i-wellbore ukususa i-debris, udaka lokugrumba, kunye nekhekhe lokucoca kwiqula kunye nokwakheka. I-viscosity yayo kunye neempawu zokumiswa zinceda ekuthwaleni amaqhekeza aqinileyo kunye nokugcina ukuhamba kwamanzi ngexesha lokucoca.
4. UkuBuyiswa kwe-Oyile eYomeleziweyo (EOR): Kwiindlela ezithile ze-EOR ezifana nezikhukhula ze-polymer, i-HEC ingasetyenziselwa njenge-agent agent yokwandisa i-viscosity yamanzi okanye izisombululo ze-polymer ezifakwe kwi-reservoir. Oku kuphucula ukusebenza kakuhle kokutshayela, kususa i-oyile eninzi, kwaye konyusa ukubuyiswa kwe-oyile kwindawo yokugcina amanzi.
5. Ukulawulwa kwelahleko yolwelo: I-HEC iyasebenza ekulawuleni ukulahleka kolwelo kwi-slurries yesamente esetyenziselwa imisebenzi yesamente. Ngokwenza ikhekhe elicwengekileyo, elingenamanzi kwi-filter yobuso, inceda ukuthintela ukulahleka kolwelo olugqithisileyo ekubunjweni, ukuqinisekisa ukwahlukaniswa kwendawo efanelekileyo kunye nokuthembeka kakuhle.
6. Fracturing Fluids: I-HEC isetyenziselwa ulwelo lwe-hydraulic fracturing ukubonelela nge-viscosity kunye nolawulo lokulahleka kolwelo. Inceda ukuthwala iipropants kwiifractures kunye nokugcina ukumiswa kwazo, ukuqinisekisa ukuhanjiswa kwe-fracture esebenzayo kunye nokubuyiswa kwamanzi ngexesha lokuvelisa.
7. Ukuvuselela kakuhle: I-HEC inokufakwa kwiincindi ezine-asidi kunye nolunye unyango lokuvuselela kakuhle ukuphucula i-rheology yolwelo, ukulawula ukulahlekelwa kwamanzi, kunye nokuphucula ukuhambelana kwamanzi kunye neemeko zokugcina amanzi. Oku kunceda ukwandisa ukusebenza konyango kunye nokwandisa imveliso kakuhle.
8. Ukugqitywa kwe-Fluids: I-HEC inokongezwa kwi-fluid yokuzalisa ukulungelelanisa i-viscosity yabo kunye neempawu zokunqunyanyiswa, ukuqinisekisa ukupakishwa kwegravel esebenzayo, ukulawulwa kwesanti, kunye nokucoca i-wellbore ngexesha lokugqitywa komsebenzi.

I-Hydroxyethyl cellulose (HEC) idlala indima ebalulekileyo kwiinkqubo ezahlukeneyo ze-oyile, inegalelo ekusebenzeni kakuhle kokomba, uzinzo lwe-wellbore, ulawulo lwamadama, kunye nokwenza ngcono imveliso. Ukuguquguquka kwayo, ukusebenza kakuhle, kunye nokuhambelana nezinye izongezo kuyenza ibaluleke kakhulu kwiinkqubo ze-oilfield fluid kunye nonyango.
