I-Hydroxyethyl Cellulose ku-Fracturing Fluid ekubhobozeni uwoyela

I-Hydroxyethyl cellulose (HEC) ngezinye izikhathi isetshenziswa oketshezini lokuqhekeka olusetshenziswa emisebenzini yokubhoboza uwoyela, ikakhulukazi ekuqhekekeni kwe-hydraulic, okwaziwa kakhulu ngokuthi i-fracking. Uketshezi lokuqhekeka lufakwa emgodini ngengcindezi ephezulu ukuze kudaleke ukuqhekeka ekwakhekeni kwamadwala, okuvumela ukukhishwa kukawoyela negesi. Nansi indlela i-HEC engasetshenziswa ngayo oketshezini lokuqhekeka:

1. Ukuguqulwa kwe-Viscosity: I-HEC isebenza njengoguquli we-rheology, isiza ukulawula i-viscosity yoketshezi lokuqhekeka. Ngokulungisa ukuhlushwa kwe-HEC, opharetha bangakwazi ukulungisa i-viscosity ukuze bafinyelele izakhiwo zoketshezi lokuqhekeka ezifiselekayo, baqinisekise ukuthuthwa koketshezi okuphumelelayo nokudalwa kokuqhekeka.
2. Ukulawulwa Kokulahlekelwa Uketshezi: I-HEC ingasiza ekulawuleni ukulahleka koketshezi ekwakhekeni ngesikhathi sokuqhekeka kwe-hydraulic. Yakha ikhekhe lokuhlunga elincane, elingangenwa amanzi ezindongeni zokuqhekeka, inciphise ukulahleka koketshezi futhi ivimbele ukulimala kokwakheka. Lokhu kusiza ukugcina ubuqotho bokuqhekeka nokuqinisekisa ukusebenza kahle kwedamu.
3. Ukumiswa Kwe-Proppant: Uketshezi lokuqhekeka luvame ukuqukatha ama-proppants, njengesihlabathi noma izinhlayiya ze-ceramic, ezithwalwa zingene emaphukeni ukuze zihlale zivulekile. I-HEC isiza ekumiseni la ma-proppants ngaphakathi koketshezi, ivimbele ukuhlala kwawo futhi iqinisekise ukusatshalaliswa okufanayo ngaphakathi kwamaphukeni.
4. Ukuhlanzwa Kokuqhekeka: Ngemva kwenqubo yokuqhekeka, i-HEC ingasiza ekuhlanzeni uketshezi lokuqhekeka oluvela kunethiwekhi yomgodi kanye nokuqhekeka. Izakhiwo zayo zokulawula ukuqina kanye nokulahlekelwa uketshezi zisiza ukuqinisekisa ukuthi uketshezi lokuqhekeka lungatholakala kahle emthonjeni, okuvumela ukukhiqizwa kukawoyela negesi ukuthi kuqale.
5. Ukuhambisana Nezithasiselo: I-HEC iyahambisana nezithasiselo ezahlukahlukene ezivame ukusetshenziswa ekuqhekekeni koketshezi, okuhlanganisa ama-biocides, ama-corrosion inhibitors, kanye nama-friction reducers. Ukuhambisana kwayo kuvumela ukwakheka koketshezi lokuqhekeka okwenziwe ngokwezifiso olulungiselelwe izimo ezithile zomthombo kanye nezidingo zokukhiqiza.
6. Ukuzinza Kwezinga Lokushisa: I-HEC ibonisa ukuzinza okuhle kokushisa, okwenza ifaneleke ukusetshenziswa koketshezi lokuqhekeka oluvezwe emazingeni okushisa aphezulu. Igcina izakhiwo zayo ze-rheological kanye nokusebenza kahle njengesithasiselo soketshezi ngaphansi kwezimo ezimbi kakhulu, iqinisekisa ukusebenza okuqhubekayo ngesikhathi sokuqhekeka kwe-hydraulic.

I-Hydroxyethyl cellulose (HEC) ingadlala indima ebalulekile ekwakhiweni koketshezi lokuqhekeka kwe-fracturing ukuze kusetshenziswe ukubhoboza uwoyela. Ukuguqulwa kwayo kwe-viscosity, ukulawula ukulahleka koketshezi, ukumiswa kwe-proppant, ukuhambisana nezithasiselo, ukuqina kokushisa, nezinye izakhiwo kunegalelo ekusebenzeni nasekuphumeleleni kwemisebenzi yokuqhekeka kwe-hydraulic. Kodwa-ke, kubalulekile ukucabangela izici ezithile zedamu kanye nezimo zemithombo lapho uklama ukwakheka koketshezi lokuqhekeka oluqukethe i-HEC.
