I-Hydroxy Ethyl Cellulose (HEC) - ukugaya amafutha

I-Hydroxyethyl cellulose (HEC) ithola ukusetshenziswa ezimbonini ezihlukahlukene, kuhlanganise nomkhakha wokumba uwoyela.Ekubholeni uwoyela, i-HEC yenza izinjongo eziningana ngenxa yezakhiwo zayo eziyingqayizivele.Nansi indlela i-HEC esetshenziswa ngayo ekubholeni uwoyela:

1. I-Viscosifier: I-HEC isetshenziswa njenge-viscosifier kuketshezi lokumba ukuze kulawulwe i-rheology futhi kuthuthukiswe izakhiwo zoketshezi.Ngokulungisa ukugxila kwe-HEC, i-viscosity yokumba uketshezi ingalungiswa ukuze ihlangabezane nezidingo ezithile, njengokugcina ukuqina kwembobo, ukuthwala ama-drill cuttings, nokulawula ukulahlekelwa uketshezi.
2. Ukulawulwa Kokulahlekelwa Kwe-Fluid: I-HEC isebenza njenge-ejenti yokulawula ukulahlekelwa uketshezi emanzini okumba, okusiza ukunciphisa ukulahlekelwa uketshezi ekubunjweni.Lesi sakhiwo sibalulekile ekugcineni ubuqotho bomthombo wemithombo, ukuvimbela ukulimala kokwakheka, nokuthuthukisa ukusebenza kahle kokumba.
3. I-Suspension Agent: I-HEC isiza ukumisa okwesikhashana futhi iphathe izinto ezisikiwe zokubhoboza kanye nezinto eziqinile ngaphakathi koketshezi lokumba, ukuvimbela ukuzinza kanye nokuqinisekisa ukususwa okuphumelelayo emgodini womthombo.Lokhu kusiza ekugcineni ukusimama komthombo kanye nokuvimbela izinkinga ezifana nepayipi elibhajwe noma ukunamathela okuhlukile.
4. I-Thickener: I-HEC isebenza njenge-ejenti ejiyayo ekwenziweni kodaka, ikhulise i-viscosity futhi ithuthukise ukumiswa kwezinto eziqinile.Izakhiwo zokujiya ezithuthukisiwe zifaka isandla ekuhlanzweni okungcono kwemigodi, ukuzinza kwemigodi okuthuthukisiwe, kanye nemisebenzi yokumba eshelelayo.
5. Ukugcobisa Okuthuthukisiwe: I-HEC ingathuthukisa ukuthambisa kuketshezi lokumba, inciphise ukungqubuzana phakathi kwentambo yokubhoboza nezindonga zomthombo.Ukugcoba okuthuthukisiwe kusiza ukunciphisa i-torque nokuhudula, ukuthuthukisa ukusebenza kahle kokumba, nokwelula impilo yezinto zokusebenza zokumba.
6. Ukuzinza Kwezinga Lokushisa: I-HEC ibonisa ukuzinza okuhle kwezinga lokushisa, igcina izakhiwo zayo ze-rheological phezu kwezinhlobonhlobo zamazinga okushisa ahlangabezane nazo ngesikhathi sokusebenza kokumba.Lokhu kuyenza ifanelekele ukusetshenziswa kuzo zombili izindawo zokumba ezijwayelekile nezisezingeni eliphezulu.
7. Inobungani Nemvelo: I-HEC iyakwazi ukubola futhi ihambisana nemvelo, okuyenza ifanelekele ukusetshenziswa ezindaweni zokumba ezizwelayo emvelweni.Ubunjalo bayo obungenabo ubuthi kanye nomthelela ophansi kwezemvelo kunomthelela ezenzweni zokumba ezisimeme.

I-HEC idlala indima ebalulekile emisebenzini yokumba uwoyela ngokunikeza ukulawula kwe-viscosity, ukulawulwa kokulahlekelwa uketshezi, ukumiswa, ukuqina, ukugcoba, ukuzinza kwezinga lokushisa, nokuhambisana kwemvelo.Izakhiwo zayo eziguquguqukayo ziyenza ibe isithasiselo esibalulekile oketshezini lokumba, ibe nesandla emikhubeni yokumba ephephile, ephumelelayo, nebhekele imvelo.
