I-Hydroxyethyl Cellulose kuFluid Fracturing Emgodini Kawoyela

I-Hydroxyethyl cellulose (HEC) kwesinye isikhathi isetshenziswa oketshezini oluqhekekayo olusetshenziswa emisebenzini yokumba uwoyela, ikakhulukazi ku-hydraulic fracturing, okwaziwa ngokujwayelekile ngokuthi i-fracking.Uketshezi oluqhekekayo lujovelwa emthonjeni ngomfutho ophezulu ukuze kudaleke ukuqhekeka ekwakhekeni kwamadwala, okuvumela ukukhishwa kukawoyela negesi.Nansi indlela i-HEC engasetshenziswa ngayo kuketshezi oluqhekekayo:

1. Ukuguqulwa Kwe-Viscosity: I-HEC isebenza njengesilungisi se-rheology, esiza ukulawula i-viscosity yoketshezi oluphukayo.Ngokulungisa ukugxila kwe-HEC, opharetha bangakwazi ukulungisa i-viscosity ukuze bafinyelele izakhiwo ezifiselekayo ze-fracturing fluid, ukuqinisekisa ukuthuthwa kwamanzi okuphumelelayo nokudalwa kokuphuka.
2. Ukulawulwa Kokulahleka Kwe-Fluid: I-HEC ingasiza ekulawuleni ukulahlekelwa uketshezi ekwakhekeni ngesikhathi sokuqhekeka kwe-hydraulic.Yakha ikhekhe lokuhlunga elincanyana, elingenakunyakaziswa ezindongeni zokuphuka, ukunciphisa ukulahlekelwa kwamanzi nokuvimbela ukulimala ekubunjweni.Lokhu kusiza ukugcina ubuqotho bokuphuka nokuqinisekisa ukusebenza kahle kwe-reservoir.
3. I-Proppant Suspension: Uketshezi oluqhekekayo luvame ukuqukatha ama-proppants, njengesihlabathi noma izinhlayiya ze-ceramic, ezithwalwa kuma-fractures ukuze zihlale zivulekile.I-HEC isiza ukumisa lawa ma-propants ngaphakathi koketshezi, ukuvimbela ukuhlaliswa kwawo kanye nokuqinisekisa ukusatshalaliswa okufanayo phakathi kokuqhekeka.
4. I-Fracture Cleanup: Ngemva kwenqubo yokuqhekeka, i-HEC ingasiza ekuhlanzeni uketshezi oluphuma ku-wellbore kanye nenethiwekhi ye-fracture.I-viscosity yayo kanye nezakhiwo zokulawula ukulahlekelwa koketshezi zisiza ukuqinisekisa ukuthi uketshezi oluqhekekayo lungatholakala kahle emthonjeni, okuvumela ukukhiqizwa kukawoyela negesi ukuthi kuqale.
5. Ukuhambisana Nezithasiselo: I-HEC ihambisana nezithasiselo ezihlukahlukene ezivame ukusetshenziswa kuketshezi oluqhekekayo, okuhlanganisa ama-biocides, ama-corrosion inhibitors, nezinciphisi ze-friction.Ukuhambisana kwayo kuvumela ukwakheka koketshezi oluqhekekayo olwenziwe ngokwezifiso oluhambisana nezimo ezithile zomthombo kanye nezidingo zokukhiqiza.
6. Ukuqina Kwezinga Lokushisa: I-HEC ibonisa ukuzinza okuhle kokushisa, okuyenza ifanelekele ukusetshenziswa kuketshezi oluqhekekayo oluvezwe emazingeni okushisa aphezulu.Igcina izakhiwo zayo ze-rheological kanye nokusebenza kahle njengesengezo samanzi ngaphansi kwezimo ezimbi kakhulu, iqinisekisa ukusebenza okungaguquki ngesikhathi sokusebenza kwe-hydraulic fracturing.

I-Hydroxyethyl cellulose (HEC) ingadlala indima ebalulekile ekwakhiweni koketshezi oluqhekekayo lwezinhlelo zokusebenza zokumba uwoyela.Ukuguqulwa kwe-viscosity yayo, ukulawulwa kokulahlekelwa uketshezi, ukumiswa kwe-propant, ukuhambisana nezithasiselo, ukuzinza kwezinga lokushisa, nezinye izakhiwo kunomthelela ekusebenzeni nasekuphumeleleni kokusebenza kwe-hydraulic fracturing.Nokho, kubalulekile ukucabangela izici ezithile zechibi nezimo zomthombo lapho uklama ukwakheka koketshezi oluphukayo oluqukethe i-HEC.
