I-Hydroxyyethyl cellulose ku-fluaring fluad ekubizeni uwoyela

I-Hydroxyyethyl cellulose (I-HEC) kwesinye isikhathi isetshenziswa oketshezi olwehlaselayo osetshenziswa ekusebenzeni kwamafutha, ikakhulukazi ekuphumeni kwe-hydraulic, eyaziwa kakhulu ngokuthi i-fracking. Amanzi acwebezelayo afakwa emthonjeni wengcindezi ephezulu yokwakha ama-fractures ekwakhekeni kwamadwala, okuvumela ukukhishwa kwamafutha negesi. Nakhu ukuthi i-HEC ingafakwa kanjani ekuphumeni uketshezi:

1. Ukuguqulwa kwe-VisCosity: I-HEC isebenza njengesiguquli se-Rheology, isiza ukulawula i-viscosity yoketshezi lokuphupha. Ngokushintsha ukugxila kwe-HEC, ama-opharetha angavumelanisa ne-viscosity ukufeza izakhiwo ezifiselekayo zokuphupha, uqinisekise ukuthuthukiswa koketshezi okusebenzayo kwezokuThutha kanye nokwakhiwa kwe-flacture.
2. Ukulawulwa kokulahlekelwa yi-Fluid: I-HEC ingasiza ekulandiseni ukulahlekelwa uketshezi ekwakhekeni ngesikhathi sokuphupha kwe-hydraulic. Yakha ikhekhe elincanyana, elingenakufinyeleleka, elingenakufinyeleleka ezindongeni zokuphuka, ukunciphisa ukulahleka koketshezi kanye nokuvimbela ukulimala kokwakheka. Lokhu kusiza ukugcina ubuqotho bokuphuka futhi kuqinisekise ukusebenza kwe-reservoir efanele.
3. Ukumiswa kweProppant: Ukuqhekeka koketshezi kuvame ukuqukatha ama-propunts, njengezinambuzane noma izinhlayiya ze-ceramic, ezithathwa ekuqhekekeni ukuze zizigcine zivulekile. I-HEC isiza ukumisa okwesikhashana la ma-propunt ngaphakathi koketshezi, ukuvikela ukulungisa kwabo kanye nokuqinisekisa ukusatshalaliswa okufanayo ngaphakathi kwama-fractures.
4. I-Fracture Cleasup: Ngemuva kwenqubo yokuphupha, i-HEC ingasiza ekuhlanzeni uketshezi oluhlasele kusuka kunethiwekhi ye-Wellbore ne-Fracture. I-viscosity yayo yokulawula ukulahla kwamanzi kusiza ukuqinisekisa ukuthi i-fluad ephuphayo ingalulama kahle emthonjeni, ivumela ukukhiqizwa kwamafutha negesi ukuba iqale.
5. Ukuvumelana kwezengezo: I-HEC iyahambelana nezithasiselo ezahlukahlukene ezisetshenziswa kakhulu ekuphumeni uketshezi, kufaka phakathi ama-biocides, ukubhuculeka inhibitors, kanye nokwehliswa kwezingxabano. Ukuhambisana kwayo kuvumela ukwakhiwa koketshezi olwenziwe ngokwezifiso olwenziwe ngezimo ezithile nezidingo zokukhiqiza.
6. Ukuqina kokushisa: I-HEC ikhombisa ukuqina okuhle okushisayo, okwenza kube lula ukusetshenziswa ogwini oluvezwe kumazinga okushisa aphezulu we-Downhole. Igcina izakhiwo zayo ezimbongini kanye nokusebenza kahle njengesengezo se-fluid ngaphansi kwezimo ezimbi kakhulu, iqinisekisa ukusebenza okungaguquki ngesikhathi sokuphupha kwe-hydraulic.

IHydroxYethyl Cellulose (I-HEC) ingadlala indima ebalulekile ekwakhekeni koketshezi lwamafutha okumba izicelo. Ukuguqulwa kwayo kwe-viscosity, Ukulawulwa kokulahlekelwa koketshezi, ukumiswa kwe-proppant, ukuhambisana nezithasiselo, ukuqina kokushisa, nezinye izakhiwo kufaka isandla ekusebenzeni kahle nasekuphumeleleni kwemisebenzi ye-hydraulic ukuphupha ukusebenza. Kodwa-ke, kubalulekile ukucubungula izici ezithile ze-reservoir kanye nezimo ezinhle lapho uhlela ukugcwala koketshezi okuqukethe i-HEC.
