Tšebeliso eaCMC e OilfieldIndasteri

Carboxymethyl cellulose (CMC) e sebelisoa haholo indastering ea oli bakeng sa lits'ebetso tse fapaneng ka lebaka la thepa le ts'ebetso ea eona e ikhethang.E sebetsa e le tlatsetso e feto-fetohang marong a ho cheka, maro a ho tlatsa, le li-slurries tsa samente, har'a lits'ebetso tse ling.Mona ke tse ling tsa ts'ebeliso e tloaelehileng ea CMC indastering ea oli:

1. Mekelikeli ea ho Cheka:

  • Viscosifier: CMC e sebelisoa e le sesebelisoa sa viscosifying marong a chekang a thehiloeng metsing ho eketsa viscosity le ho ntlafatsa bokhoni ba ho jara mokelikeli.E thusa ho boloka botsitso ba seliba, ho emisa ho itšeha, le ho laola tahlehelo ea mokelikeli nakong ea ho cheka.
  • Taolo ea Tahlehelo ea Mokelikeli: CMC e sebetsa e le ntho e laolang tahlehelo ea mokelikeli ka ho etsa kuku e tšesaane, e ke keng ea qoelisoa leboteng la seliba, e thibelang tahlehelo e feteletseng ea mokelikeli sebopehong.
  • Thibelo ea Shale: CMC e thusa ho thibela ho ruruha le ho hasana ha shale ka ho koahela libaka tsa shale le ho thibela metsi a likaroloana tsa letsopa, ho fokotsa kotsi ea ho se tsitse ha seliba le liketsahalo tsa lipeipi tse khomaretsoeng.
  • Clay Stabilization: CMC e tsitsisa liminerale tsa letsopa tse sebetsang ka har'a maro a chekang, ho thibela ho ruruha ha letsopa le ho falla, le ho ntlafatsa ts'ebetso ea ho cheka ka har'a libopeho tse nang le letsopa le ruileng.

2. Mekelikeli ea ho Tlatsa:

  • Taolo ea Tahlehelo ea Mokelikeli: CMC e eketsoa ho maro a tlatsang ho laola tahlehelo ea mokelikeli sebopeho nakong ea ho phethela hantle le ts'ebetso ea ho sebetsa.E thusa ho boloka botšepehi ba sebopeho le ho thibela tšenyo ea sebopeho.
  • Shale Stabilization: CMC e thusa ho tsitsisa shale le ho thibela ho phalla ha shale le ho ruruha nakong ea ts'ebetso ea ho phethela, ho fokotsa ho se tsitse ha liliba le ho ntlafatsa tlhahiso ea hantle.
  • Filter Cake Formation: CMC e khothalletsa ho thehoa ha junifomo, kaka e ke keng ea qojoa sefahlehong sa sebopeho, ho fokotsa khatello ea phapang le ho falla ha mokelikeli ho thehoa.

3. Li-slurries tsa samente:

  • Keketso ea Tahlehelo ea Mokelikeli: CMC e sebetsa e le tlatsetso ea tahlehelo ea mokelikeli ho samenteng li-slurries ho fokotsa tahlehelo ea mokelikeli ka har'a mekhoa e kenang le ho ntlafatsa bokhoni ba ho beha samente.E thusa ho etsa bonnete ba ho itšehla thajana ho loketseng le ho kopanya samente.
  • Thickening Agent: CMC e sebetsa e le ntho e tenya ka har'a li-slurries tsa samente, e fana ka taolo ea viscosity le ho matlafatsa pompo le ho emisoa ha likaroloana tsa samente nakong ea ho beoa.
  • Rheology Modifier: CMC e fetola rheology ea li-slurries tsa samente, e ntlafatsa thepa ea ho phalla, ho hanyetsa le botsitso tlas'a maemo a tlaase.

4. Phallo e Matlafalitsoeng ea Oli (EOR):

  • Moroallo oa Metsi: CMC e sebelisoa ts'ebetsong ea likhohola tsa metsi ho ntlafatsa ts'ebetso ea ho fiela le ho ntlafatsa pholiso ea oli ho tsoa matamong.E eketsa viscosity ea metsi a ente, e ntlafatsa taolo ea motsamao le katleho ea phallo.
  • Meroallo ea Polymer: Lits'ebetsong tsa likhohola tsa polymer, CMC e sebelisoa e le setsi sa taolo ea motsamao ho ntlafatsa tumellano ea li-polymer tse kentsoeng le ho eketsa ts'ebetso ea ho fiela ha maro a fetisoang.

5. Mekelikeli e Fracturing:

  • Fluid Viscosifier: CMC e sebelisoa e le sesebelisoa sa viscosifying ka har'a maro a hydraulic fracturing ho eketsa viscosity ea mokelikeli le matla a ho jara.E thusa ho theha le ho boloka fractures sebopehong le ho ntlafatsa lipalangoang le ho beoa hantle.
  • Ntlafatso ea Fracture Conductivity: CMC e thusa ho boloka botšepehi ba sephutheloana le ts'ebetso ea fracture ka ho fokotsa ho lutla ha mokelikeli ho thehoeng le ho thibela ho ts'oaroa ha proppant.

Ka kakaretso,carboxymethyl cellulose(CMC) e bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri ea oli, ho kenyeletsoa maro a ho cheka, maro a phethelang, li-slurries tsa samente, ho hlaphoheloa ha oli e ntlafalitsoeng (EOR), le maro a robehang.Ho feto-fetoha ha eona joalo ka moemeli oa taolo ea tahlehelo ea mokelikeli, viscosifier, shale inhibitor, le rheology modifier e e etsa tlatsetso e hlokahalang bakeng sa ho netefatsa ts'ebetso e atlehileng le e atlehileng ea lebala la oli.
