Tšebeliso ea CMC ho Petroleum

Moetso oa CMC oa boemo ba peterole: PAC- HV PAC- LV PAC-L PAC-R PAC-RECMC-HVCMC- LV

1. Mesebetsi ea PAC le CMC lebaleng la oli ke e latelang:

1. Seretse se nang le PAC le CMC se ka etsa hore lebota la seliba le thehe kuku e tšesaane le e tiileng ea sefene e nang le "permeability" e tlase, e fokotsa tahlehelo ea metsi;

2. Ka mor'a ho eketsa PAC le CMC seretseng, mochine oa ho cheka o ka fumana matla a tlaase a pele a ho kuta, e le hore seretse se be bonolo ho ntša khase e phuthetsoeng ho sona, 'me ka nako e ts'oanang, litšila li lahleloa ka potlako seretseng. sekoti;

3. Ho cheka seretse, joalo ka lintho tse ling tse emisitsoeng le ho qhalakanngoa, ho na le sethala se itseng sa bophelo. Ho eketsa PAC le CMC ho ka etsa hore e tsitse le ho lelefatsa bophelo ba sethala.

2. PAC le CMC li na le thepa e latelang e babatsehang lits'ebetsong tsa oli:

1. Boemo bo phahameng ba ho nkela sebaka, ho lumellana hantle ha ho nkela sebaka, viscosity e phahameng, tekanyo e tlaase, ho ntlafatsa ka katleho katleho ea tšebeliso ea seretse;

2. Ho hanyetsa mongobo o motle, ho hanyetsa letsoai le ho hanyetsa alkali, ho loketse metsi a hloekileng, metsi a leoatle le seretse se tletseng metsi a letsoai a nang le metsi;

3. Boleng ba kaka e entsoeng ka seretse e ntle ebile e tsitsitse, e ka khonang ho tsitsisa sebopeho sa mobu o bonolo le ho thibela lerako la seliba hore le se ke la oa;

4. E loketse tsamaiso ea seretse eo litaba tsa eona tse tiileng li leng thata ho li laola 'me li na le liphetoho tse ngata.

3. Litšobotsi tsa ts'ebeliso ea CMC le PAC ho cheka oli:

1. E na le bokhoni bo phahameng ba ho laola tahlehelo ea metsi, haholo-holo ho fokotsa tahlehelo ea matla, e ka laolang tahlehelo ea metsi ka tekanyo e phahameng ka tekanyo e tlaase ntle le ho ama thepa e meng ea seretse;

2. Ho hanyetsa mocheso o motle le ho hanyetsa letsoai ho babatsehang. Tlas'a motsoako o itseng oa letsoai, e ntse e ka ba le bokhoni bo botle ba ho fokotsa tahlehelo ea metsi le rheology e itseng. Ka mor'a ho qhibiliha ka metsing a letsoai, viscosity e batla e sa fetohe, haholo-holo e loketseng likopo tsa offshore. Litlhokahalo tsa ho cheka le seliba se tebileng;

3. E ka laola hantle rheology ea seretse, e na le thixotropy e ntle, 'me e loketse seretse leha e le sefe se nang le metsi ka metsing a hloekileng, metsi a leoatle, le metsi a letsoai a tletseng letsoai;

4. Ho feta moo, PAC e sebelisoa e le mokelikeli o samenteng, o ka thibelang mokelikeli ho kena masobeng le ho robeha;

5. Filtrate e lokiselitsoeng le PAC e ka mamella tharollo ea 2% ea KCL (e tlameha ho ekeletsoa ha ho etsoa filtrate) 'me e na le solubility e ntle, e bonolo ho e sebelisa, e ka lokisoa setšeng,' me e na le lebelo le potlakileng la gelation le bokhoni bo matla ba ho jara lehlabathe. E sebelisoa ka sebopeho, 'me phello ea eona ea khatello ea khatello e ntle haholo.
