Liphello tsa Hydroxy Ethyl Cellulose ho OilDrilling

Hydroxyethyl cellulose (HEC) e sebelisoa marong a ho cheka oli bakeng sa merero e fapaneng ka lebaka la thepa ea eona e ikhethang. Mona ke tse ling tsa litlamorao tsa HEC ho cheka oli:

1. Taolo ea Viscosity: HEC e sebetsa e le rheology modifier ho maro a ho cheka, ho thusa ho laola viscosity le thepa ea phallo ea mokelikeli. E ntlafatsa viscosity ea mokelikeli oa ho cheka, e leng oa bohlokoa bakeng sa ho emisa le ho tsamaisa li-cuttings tsa ho cheka holimo, ho thibela ho lula ha tsona le ho boloka botsitso ba lesoba.
2. Taolo ea Tahlehelo ea Mekelikeli: HEC e thusa ho fokotsa tahlehelo ea mokelikeli ho tsoa ho maro a ho cheka hore e be mekhoa e kenang, ka ho etsa joalo e boloka botsitso ba hantle le ho thibela tšenyo ea sebopeho. E etsa kuku e tšesaane, e ke keng ea qojoa sefahlehong sa sebopeho, e fokotsa tahlehelo ea maro a ho cheka sebopeho le ho fokotsa tlhaselo ea mokelikeli.
3. Ho Hloekisa Likoti: HEC e thusa ho hloekisoa ha mekoti ka ho ntlafatsa bokhoni ba mokelikeli oa ho cheka le ho thusa ho tlosoa ha likheo tsa ho cheka selibeng. E ntlafatsa thepa ea ho emisa ea mokelikeli, ho thibela lintho tse tiileng hore li se ke tsa lula le ho bokellana ka tlaase ho sekoti.
4. Botsitso ba Mocheso: HEC e bonts'a botsitso bo botle ba mocheso 'me e khona ho mamella mefuta e mengata ea mocheso e kopanang le eona nakong ea ts'ebetso ea ho cheka. E boloka thepa ea eona ea rheological le katleho e le motsoako oa mokelikeli tlas'a maemo a phahameng a mocheso, ho netefatsa ts'ebetso e tsitsitseng libakeng tse thata tsa ho cheka.
5. Mamello ea Letsoai: HEC e lumellana le maro a phahameng a ho cheka letsoai 'me e bontša mamello e ntle ea letsoai. E ntse e sebetsa e le sesebelisoa sa rheology modifier le se laolang tahlehelo ea mokelikeli marong a ho cheka a nang le matsoai a mangata kapa matsoai, a atisang ho kopana le mesebetsi ea ho cheka kantle ho naha.
6. E Setsoalle le Tikoloho: HEC e tsoa mehloling ea selulose e nchafalitsoeng 'me e baballa tikoloho. Tšebeliso ea eona ho maro a ho cheka e thusa ho fokotsa tšusumetso ea tikoloho ea ts'ebetso ea ho cheka ka ho fokotsa tahlehelo ea mokelikeli, ho thibela tšenyo ea sebopeho, le ho ntlafatsa botsitso ba mekoti.
7. Ho lumellana le Li-Additives: HEC e lumellana le mefuta e mengata ea li-additives tsa mokelikeli oa ho cheka, ho akarelletsa le li-shale inhibitors, lubricant le li-weighting agents. E ka kenyelletsoa habonolo mekhoeng ea mokelikeli oa ho cheka ho fihlela litšobotsi tse lakatsehang tsa ts'ebetso le ho tobana le mathata a itseng a ho cheka.

Hydroxyethyl cellulose (HEC) ke tlatsetso e feto-fetohang ka har'a maro a ho cheka oli, moo e kenyang letsoho taolong ea viscosity, taolo ea tahlehelo ea mokelikeli, ho hloekisoa ha lesoba, botsitso ba mocheso, mamello ea letsoai, ts'ireletso ea tikoloho, le ho lumellana le li-additives tse ling. Katleho ea eona ea ho ntlafatsa ts'ebetso ea mokelikeli oa ho cheka e etsa hore e be karolo ea bohlokoa ts'ebetsong ea tlhahiso ea oli le khase.
