Hydroxyethyl Cellulose ka har'a mokelikeli oa ho pshatla oli

Hydroxyethyl cellulose (HEC) ka linako tse ling e sebelisoa mokelikeling oa ho qhaqha o sebelisoang mesebetsing ea ho cheka oli, haholo-holo ho qhaqha oli ka metsi, e tsejoang haholo e le fracking. Mekelikeli ea ho qhaqha e kenngoa ka har'a seliba ka khatello e phahameng ho baka mapetso mafikeng, e leng se lumellang ho ntšoa ha oli le khase. Mokhoa oa HEC o ka sebelisoa mokelikeling oa ho qhaqha oli ke ona:

1. Phetoho ea Viscosity: HEC e sebetsa e le mofetoleli oa rheology, e thusang ho laola viscosity ea mokelikeli oa ho robeha. Ka ho fetola mahloriso a HEC, basebetsi ba ka fetola viscosity ho fihlela litšobotsi tse lakatsehang tsa mokelikeli oa ho robeha, ho netefatsa hore ho tsamaisoa ha mokelikeli ka katleho le ho etsoa ha ho robeha.
2. Taolo ea Tahlehelo ea Mokelikeli: HEC e ka thusa ho laola tahlehelo ea mokelikeli sebopehong nakong ea ho pshatleha ha metsi ka metsi. E etsa kuku e tšesaane, e sa keneng ka metsing maboteng a ho pshatleha, e fokotsa tahlehelo ea mokelikeli le ho thibela tšenyo sebopehong. Sena se thusa ho boloka botsitso ba ho pshatleha le ho netefatsa ts'ebetso e ntle ea letamo.
3. Ho fanyeha ha Proppant: Metsi a qhetsolang hangata a na le di-proppant, tse kang lehlabathe kapa dikarolwana tsa ceramic, tse iswang ka hara maqeba ho di boloka di bulehile. HEC e thusa ho fanyeha di-proppant tsena ka hara mokelikeli, e thibela ho dula ha tsona le ho netefatsa kabo e tshwanang ka hara maqeba.
4. Ho Hloekisa ho Robeha: Kamora ts'ebetso ea ho robeha, HEC e ka thusa ho hloekisa mokelikeli oa ho robeha ho tsoa marang-rang a seliba le a ho robeha. Matla a eona a ho teteana le taolo ea tahlehelo ea mokelikeli a thusa ho netefatsa hore mokelikeli oa ho robeha o ka fumanoa ka katleho selibeng, e leng se lumellang tlhahiso ea oli le khase ho qala.
5. Ho tsamaellana le Lintho tse Ekelitsoeng: HEC e tsamaellana le lintho tse ling tse sebelisoang hangata marong a ho qhaqha, ho kenyeletsoa le lintho tse bolaeang likokoana-hloko, lithibela-mafu tsa ho bola, le lintho tse fokotsang khohlano. Ho tsamaellana ha eona ho lumella ho etsoa ha maro a ho qhaqha a entsoeng ka mokhoa o ikhethileng a etselitsoeng maemo a itseng a seliba le litlhoko tsa tlhahiso.
6. Ho Tsitsa ha Mocheso: HEC e na le botsitso bo botle ba mocheso, e leng se etsang hore e lokele ho sebediswa marong a ho qhaqha a pepesehetseng mocheso o phahameng. E boloka thepa ya yona ya rheological le katleho e le sehlomathiso sa mokelikeli tlasa maemo a feteletseng, e netefatsa tshebetso e tsitsitseng nakong ya mesebetsi ya ho qhaqha ha hydraulic.

Hydroxyethyl cellulose (HEC) e ka bapala karolo ea bohlokoa ho thehoeng ha maro a fracturing bakeng sa lits'ebetso tsa ho cheka oli. Phetoho ea eona ea viscosity, taolo ea tahlehelo ea mokelikeli, ho emisoa ha proppant, ho lumellana le lintho tse ling tse tlatsetsang, botsitso ba mocheso, le litšobotsi tse ling li kenya letsoho katlehong le katlehong ea ts'ebetso ea fracturing ea hydraulic. Leha ho le joalo, ho bohlokoa ho nahana ka litšobotsi tse ikhethileng tsa letamo le maemo a liliba ha ho etsoa meralo ea fracturing ea mokelikeli o nang le HEC.
