Mophato oa ho Cheka Oli CMC LV

Oil drilling grade carboxymethyl cellulose (CMC) LV ke mofuta oa polymer e qhibilihang ka metsing e sebelisoang haholo indastering ea oli le khase. Ke motsoako o fetotsoeng oa cellulose, motsoako oa tlhaho o fumanehang maboteng a lisele tsa limela. CMC LV e atisa ho sebelisoa e le viscosifier, rheology modifier, liquid loss reducer, le shale inhibitor ho cheka maro. Sehloohong sena, re tla tšohla thepa, lits'ebetso, le melemo ea sehlopha sa ho cheka oli CMC LV.

Thepa ea CMC LV

Mokhahlelo oa ho cheka oli CMC LV ke phofo e tšoeu kapa e sa hloekang, e sa nkheng, 'me e sa latsoeheng e qhibilihang haholo metsing. E tsoa ho selulose ka ts'ebetso ea phetoho ea lik'hemik'hale e kenyelletsang ho kenyelletsoa ha lihlopha tsa carboxymethyl molek'hule ea cellulose. Tekanyo ea substitution (DS) e lekanya palo ea lihlopha tsa carboxymethyl ho yuniti ea tsoekere ka molek'hule ea selulose, e amang thepa ea CMC LV.

CMC LV e na le lisebelisoa tse 'maloa tse etsang hore e be thuso ho maro a ho cheka. Ke polymer e qhibilihang ka metsi e ka etsang litharollo tsa viscous ka metsi. E boetse e na le pH-sensitive, le viscosity ea eona e fokotseha ha pH e ntse e eketseha. Thepa ena e e lumella ho sebelisoa maemong a fapaneng a pH. Ho feta moo, CMC LV e na le mamello e phahameng ea letsoai, e etsang hore e tšoanelehe bakeng sa tšebeliso ea maro a ho cheka a thehiloeng ho brine.

Lisebelisoa tsa CMC LV

Viscosifier
E 'ngoe ea ts'ebeliso ea mantlha ea CMC LV marong a ho cheka ke joalo ka viscosifier. E ka thusa ho eketsa viscosity ea mokelikeli oa ho cheka, o thusang ho emisa le ho tsamaisa li-cutlets tsa drill holimo. Thepa ena ke ea bohlokoa ka ho khetheha mesebetsing ea ho cheka moo sebopeho se ntseng se phunngoa se sa tsitsang kapa moo ho nang le kotsi ea ho lahleheloa ke potoloho.

Mofetoleli oa Rheology
CMC LV e boetse e sebelisoa e le mofetoleli oa rheology ka maro a ho cheka. E ka thusa ho laola thepa ea phallo ea mokelikeli, e leng ntho ea bohlokoa bakeng sa ho boloka botsitso ba seliba. CMC LV e ka thusa ho thibela ho putlama kapa ho lokisa lintho tse tiileng ka har'a mokelikeli oa ho cheka, e leng se ka lebisang mathateng a ho cheka.

Mokelikeli Tahlehelo Reducer
CMC LV e boetse e sebelisoa e le se fokotsang tahlehelo ea mokelikeli ka maro a ho cheka. E ka thusa ho etsa kuku e tšesaane, e ke keng ea qojoa leboteng la seliba, e thusang ho fokotsa tahlehelo ea mokelikeli oa ho cheka sebopeho. Thepa ena ke ea bohlokoa ka ho khetheha libopeho tse nang le matla a fokolang kapa mesebetsing e tebileng ea ho cheka moo litšenyehelo tsa ho potoloha ho lahlehileng li ka bang bohlokoa.

Shale Inhibitor
CMC LV e boetse e sebelisoa e le "shale inhibitor" marong a ho cheka. E ka thusa ho thibela ho ruruha le ho hasana ha libopeho tsa shale, tse ka lebisang ho se tsitseng ha hantle le ho lahleheloa ke potoloho ea mali. Thepa ena e bohlokoa ka ho khetheha ts'ebetsong ea ho cheka moo sebopeho se phuntsoeng e leng shale.

Melemo ea CMC LV

Sebetsa se Ntlafetseng sa ho Cheka
CMC LV e ka thusa ho ntlafatsa bokhoni ba ho cheka ka ho fokotsa kotsi ea ho potoloha ha mali, ho boloka botsitso ba hantle, le ho ntlafatsa thepa ea mokelikeli oa ho cheka. Thepa ena e ka thusa ho fokotsa litšenyehelo tsa ho cheka le ho ntlafatsa ts'ebetso e akaretsang ea ts'ebetso ea ho cheka.

Botsitso bo ntlafetseng ba Wellbore
CMC LV e ka thusa ho ntlafatsa botsitso ba wellbore ka ho laola thepa ea phallo ea mokelikeli oa ho cheka le ho thibela ho ruruha le ho hasana ha libopeho tsa shale. Thepa ena e ka thusa ho fokotsa kotsi ea ho putlama ha seliba kapa ho phatloha ho ka bang kotsi le ho ba kotsi.

Phello e Fokotseng ea Tikoloho
CMC LV ke lintho tse ka senyehang habonolo le tikolohong tse se nang litlamorao life kapa life tse kotsi tikolohong. Thepa ena e etsa hore e be khetho e khahlehang bakeng sa ts'ebetso ea ho cheka libakeng tse sa tsotelleng tikoloho.

Chelete e sebetsang
CMC LV ke khetho e theko e tlaase bakeng sa maro a ho cheka ha a bapisoa le lipolymer tse ling tsa maiketsetso le li-additives. E fumaneha habonolo ebile e na le litšenyehelo tse tlase ha e bapisoa le li-polymer tse ling tsa maiketsetso le li-additives, e leng se etsang hore e be khetho e ntle bakeng sa mesebetsi e mengata ea ho cheka.

Ho feto-fetoha ha maemo
CMC LV ke polima e feto-fetohang e ka sebelisoang mefuteng e mengata ea maro a ho cheka. E ka sebelisoa ka metsi a hloekileng a thehiloeng metsing, a nang le metsi a letsoai, le marotholi a thehiloeng ka oli. Ho feto-fetoha hona ho etsa hore e be polymer e tsebahalang indastering ea oli le khase.

Qetello

Oli drilling grade carboxymethyl cellulose (CMC) LV ke polymer e feto-fetohang le e sebelisoang haholo indastering ea oli le khase. Hangata e sebelisoa e le viscosifier, rheology modifier, liquid loss reducer, le shale inhibitor mekelikeli ea ho cheka. CMC LV e na le lisebelisoa tse 'maloa tse e etsang hore e be thuso ho maro a ho cheka, ho kenyelletsa le bokhoni ba eona ba ho eketsa viscosity, ho laola thepa ea phallo, ho fokotsa tahlehelo ea mokelikeli, le ho thibela ho ruruha le ho hasana ha shale. E boetse e na le litšenyehelo tse tlaase, e ka senyeha habonolo, 'me ha e na tikoloho, e leng se etsang hore e be khetho e ntle bakeng sa mesebetsi e mengata ea ho cheka. Ka ho feto-fetoha ha maemo le melemo e mengata, CMC LV e kanna ea tsoela pele ho ba polymer ea bohlokoa indastering ea oli le khase lilemo tse tlang.
