CMC e sebelisa indastering ea ho Cheka Petroleum le Oli

Carboxymethylcellulose (CMC) e sebelisoa haholo indastering ea ho cheka peterole le oli bakeng sa lits'ebetso tse fapaneng ka lebaka la thepa ea eona e ikhethang joalo ka polima e qhibilihang ka metsi. E tsoa ho cellulose, polymer ea tlhaho e fumanoang limela, ka mokhoa oa ho fetola lik'hemik'hale o hlahisang lihlopha tsa carboxymethyl. CMC e hiriloe mesebetsing ea ho cheka lebopong le kantle ho naha. Mona ke lisebelisoa tse 'maloa tsa bohlokoa tsa CMC indastering ea ho cheka peterole le oli:

1. Keketso ea Mokelikeli oa ho Epa:
   • CMC hangata e sebelisoa e le tlatsetso ea bohlokoa marong a ho cheka. E sebeletsa merero e mengata, ho kenyelletsa:
     • Viscosifier: CMC e eketsa viscosity ea mokelikeli oa ho cheka, e fana ka lubrication e hlokahalang le ho emisoa ha li-cuttings.
     • Taolo ea Tahlehelo ea Mokelikeli: CMC e thusa ho laola tahlehelo ea mokelikeli ka har'a sebopeho, ho netefatsa botsitso ba seliba.
     • Rheology Modifier: CMC e sebetsa joalo ka rheology modifier, e susumetsang thepa ea phallo ea mokelikeli oa ho cheka tlas'a maemo a fapaneng.
2. Suspension Agent:
   • Mekelikeli ea ho cheka, CMC e sebetsa e le ntho e emisang, e thibelang likaroloana tse tiileng, tse kang li-cuttings tse phuntsoeng, ho lula tlase ho seliba. Sena se thusa ho cheka ka mokhoa o atlehileng le ho tlosoa ha li-cuttings ho tsoa mokoting.
3. Lubricant le Friction Reducer:
   • CMC e fana ka lubrication mme e sebetsa joalo ka se fokotsang likhohlano marong a ho cheka. Sena se bohlokoa bakeng sa ho fokotsa khohlano lipakeng tsa pompo ea ho phunya le borehole, ho fokotsa khathatso ea lisebelisoa tsa ho cheka le ho ntlafatsa bokhoni ba ho cheka.
4. Ho tsitsisa ha Borehole:
   • CMC e thusa ho tsitsisa seliba ka ho thibela ho putlama ha libopeho tse chekiloeng. E etsa lesela le sireletsang marakong a seliba, ho matlafatsa botsitso nakong ea ts'ebetso ea ho cheka.
5. Keketso ea Cement Slurry:
   • CMC e sebelisoa e le tlatsetso ka har'a li-slurries tsa samente bakeng sa ho tiisa seliba sa oli. E ntlafatsa thepa ea rheological ea slurry ea samente, ho netefatsa ho behoa hantle le ho thibela ho arohana ha likarolo tsa samente.
6. Kamohelo e Matlafalitsoeng ea Oli (EOR):
   • Ts'ebetsong e ntlafalitsoeng ea ho khutlisa oli, CMC e ka sebelisoa e le moemeli oa taolo ea ho tsamaea. E thusa ho ntlafatsa ts'ebetso ea phallo ea maro a entetsoeng, ho thusa ho khutlisa oli e eketsehileng matamong.
7. Taolo ea Viscosity ea Mokelikeli:
   • CMC e hiriloe ho laola viscosity ea maro a ho cheka, ho netefatsa thepa e nepahetseng ea mokelikeli tlas'a maemo a fapaneng a tlase. Sena se bohlokoa bakeng sa ho boloka ts'ebetso ea ho cheka hantle le botsitso ba seliba.
8. Filter Cake Control:
   • CMC e thusa ho laola sebopeho sa likuku tse sefang maboteng a seliba nakong ea ho cheka. E kenya letsoho ho thehoeng ha kuku e tsitsitseng le e laoloang ea sefe, ho thibela tahlehelo e feteletseng ea mokelikeli le ho boloka botšepehi ba wellbore.
9. Mekelikeli ea ho Cheka Letamo:
   • Ha ho cheka letamo, CMC e sebelisoa mekelikeli ea ho cheka ho rarolla mathata a itseng a amanang le maemo a polokelo. E thusa ho boloka botsitso ba seliba le ho laola thepa ea mokelikeli.
10. Taolo ea Phallo e Lahlehileng:
    • CMC e hiriloe ho laola mathata a phallo ea mali nakong ea ho cheka. E thusa ho koala le ho koala likheo sebopehong, ho thibela tahlehelo ea maro a ho cheka libakeng tse nang le masoba kapa tse robehileng.
11. Mekelikeli e susumetsang hantle:
    • CMC e ka sebelisoa ka maro a hlasimollang hantle ho matlafatsa viscosity ea mokelikeli le ho emisa li-proppants nakong ea ts'ebetso ea hydraulic fracturing.

Ka kakaretso, carboxymethylcellulose (CMC) e bapala karolo ea bohlokoa indastering ea ho cheka peterole le oli, e tlatsetsang katlehong, botsitsong le polokehong ea ts'ebetso ea ho cheka. Mehaho ea eona e nang le mekhoa e mengata e etsa hore e be tlatsetso ea bohlokoa marong a ho cheka le li-slurries tsa samente, e sebetsanang le liqholotso tse fapaneng tse thulaneng le lipatlisiso le ho ntšoa ha mehloli ea oli le khase.
