Liphello tsa Hydroxyethyl Cellulose libakeng tsa Oil

Hydroxyethyl cellulose (HEC) e fumana lits'ebetso tse 'maloa indastering ea oli le khase, haholo libakeng tsa oli. Mona ke tse ling tsa litlamorao le ts'ebeliso ea HEC ts'ebetsong ea sebaka sa oli:

1. Mekelikeli ea ho cheka: HEC e atisa ho eketsoa ho maro a ho cheka ho laola viscosity le rheology. E sebetsa joaloka viscosifier, e fana ka botsitso le ho matlafatsa matla a ho jara a mokelikeli oa ho cheka. Sena se thusa ho emisa likhechana tsa ho cheka le lintho tse ling tse tiileng, ho li thibela ho tsitsa le ho baka tšitiso selibeng.
2. Taolo ea Potoloho e Lahlehileng: HEC e ka thusa ho laola ho potoloha ho lahlehileng nakong ea ts'ebetso ea ho cheka ka ho theha tšitiso khahlanong le tahlehelo ea mokelikeli ka har'a sebopeho sa porous. E thusa ho koala fractures le libaka tse ling tse ka khonang ho thehoa, ho fokotsa kotsi ea ho lahleheloa ke potoloho le ho se tsitse ha seliba.
3. Wellbore Cleanup: HEC e ka sebelisoa e le karolo ea metsi a hloekisang liliba ho tlosa lithōle, seretse se chekang, le kuku e sefang ho tsoa selibeng le ho bōptjoa. Viscosity ea eona le thepa ea ho emisoa li thusa ho tlosa likaroloana tse tiileng le ho boloka motsamao oa mokelikeli nakong ea ts'ebetso ea ho hloekisa.
4. Ntlafatso ea Oli e Ntlafetseng (EOR): Ka mekhoa e itseng ea EOR e kang likhohola tsa polymer, HEC e ka sebelisoa e le ntho e teteaneng ho eketsa viscosity ea metsi kapa litharollo tsa polymer tse kentsoeng ka letamong. Sena se ntlafatsa ts'ebetso ea ho fiela, se tlosa oli e ngata, 'me se ntlafatsa ho hlaphoheloa ha oli ho tsoa letamong.
5. Taolo ea Tahlehelo ea Mokelikeli: HEC e sebetsa hantle ho laola tahlehelo ea mokelikeli ka har'a li-slurries tsa samente tse sebelisoang bakeng sa ts'ebetso ea samente. Ka ho etsa kaka e tšesaane, e ke keng ea qojoa sefahlehong sa sebopeho, e thusa ho thibela tahlehelo e feteletseng ea mokelikeli ho sebopeho, ho netefatsa ho itšehla thajana ho nepahetseng le ho tšepahala hantle.
6. Fracturing Fluids: HEC e sebelisoa ka har'a maro a hydraulic fracturing ho fana ka viscosity le taolo ea tahlehelo ea mokelikeli. E thusa ho jara li-proppants ho fractures le ho boloka ho emisoa ha tsona, ho netefatsa hore ho na le conductivity e sebetsang ea fracture le ho hlaphoheloa ha metsi nakong ea tlhahiso.
7. Ho hlasimolla hantle: HEC e ka kenyelletsoa marong a acidizing le liphekolo tse ling tsa ho hlasimolla hantle ho ntlafatsa rheology ea mokelikeli, ho laola tahlehelo ea mokelikeli, le ho ntlafatsa ho lumellana ha mokelikeli le maemo a polokelo. Sena se thusa ho ntlafatsa ts'ebetso ea kalafo le ho eketsa tlhahiso e ntle.
8. Mekelikeli ea ho Tlatsa: HEC e ka eketsoa mokelikeli oa ho tlatsa ho lokisa viscosity ea bona le thepa ea ho emisa, ho netefatsa ho paka ka mokhoa o sebetsang oa lehlohlojane, taolo ea lehlabathe, le tlhoekiso ea liliba nakong ea ts'ebetso ea ho phethela.

Hydroxyethyl cellulose (HEC) e bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa sebaka sa oli, ho kenya letsoho ts'ebetsong e ntle ea ho cheka, botsitso ba seliba, taolo ea polokelo le ntlafatso ea tlhahiso. Ho feto-fetoha ha eona, ho sebetsa hantle, le ho tsamaellana le litlatsetso tse ling ho e etsa karolo ea bohlokoa lits'ebetsong le kalafong ea mokelikeli oa oli.
