Ts'ebetso e phahameng ea PAC bakeng sa maro a ho cheka a thehiloeng metsing

Polyanionic cellulose (PAC) e sebetsang hantle haholo ke tlatsetso ea bohlokoa marong a chekang metsi, e fanang ka melemo e mengata e ntlafatsang ts'ebetso ea ho cheka, botsitso ba seliba le ts'ebetso ka kakaretso. PAC ke polima e qhibilihang ka metsing e nkiloeng ho selulose, 'me tšebeliso ea eona ho maro a ho cheka e thusa ho laola rheology, tahlehelo ea mokelikeli le taolo ea ho sefa. Mona ke kamoo PAC ea ts'ebetso e phahameng e kenyang letsoho katlehong ea maro a chekang a thehiloeng metsing:

Litšobotsi tsa PAC ea Ts'ebetso e Phahameng:

1. Motsoako oa Metsi: PAC e sebetsang hantle haholo e qhibiliha habonolo ka metsing, e lumellang hore ho be bonolo ho kopanya le ho hasana lits'ebetsong tsa mokelikeli oa ho cheka.
2. Taolo ea Thickening le Rheology: PAC e sebetsa joalo ka sebonela-hōle marong a chekang, e thusang ho fihlela le ho boloka viscosity e lakatsehang le thepa ea rheological. E fana ka boitšoaro ba ho kuta, e thusa ho pompa nakong ea ho potoloha le ho hlaphoheloa ha ho kuta ha ho tsitsitse.
3. Taolo ea Tahlehelo ea Mekelikeli: PAC e etsa kuku e tšesaane, e ke keng ea qoelisoa leboteng la borehole, e fokotsang tahlehelo ea mokelikeli sebopehong. Sena se thusa ho boloka botsitso ba seliba, ho thibela tšenyo ea sebopeho, le ho fokotsa mathata a theko e boima a phallo ea mali.
4. Thempereichara le Botsitso ba Letsoai: PAC e sebetsang ka mokhoa o phahameng e etselitsoe ho boloka ts'ebetso ea eona le botsitso ho pholletsa le mefuta e mengata ea mocheso le maemo a letsoai a fumanoang nakong ea ts'ebetso ea ho cheka, ho kenyeletsoa libaka tsa mocheso o phahameng le tse nang le letsoai le phahameng.
5. Ho lumellana le Li-additives: PAC e bonts'a tšebelisano e ntle le lisebelisoa tse ling tsa mokelikeli oa ho cheka, ho kenyeletsoa li-stabilizer tsa letsopa, lubricant, li-shale inhibitors le li-weighting agents. E ka sebelisoa hammoho le li-additives tse fapaneng ho hlophisa thepa ea mokelikeli oa ho cheka ho latela maemo le lipheo tse khethehileng tsa seliba.

Melemo ea Ts'ebetso e Phahameng ea PAC Metsing a Chesang a Thehiloeng ka Metsi:

1. Tlhoekiso e Ntlafetseng ea Likoti: PAC e thusa ho emisa likhechana tsa ho cheka le lithōle ka har'a mokelikeli oa ho cheka, ho khothalletsa ho ntšoa ka mokhoa o nepahetseng selibeng le ho li thibela ho tsitsa le ho baka mathata a fatše.
2. Matla a Ntlafetseng: Ho ba teng ha PAC marong a ho cheka ho fokotsa khohlano pakeng tsa khoele ea ho cheka le seliba, ho ntlafatsa bokhoni ba ho cheka, ho fokotsa torque le ho hula, le ho lelefatsa bophelo ba lisebelisoa tsa ho cheka.
3. Tsitsitseng Wellbore: PAC e thusa ho thibela mathata a ho se tsitse ha wellbore, joalo ka ho holisa lesoba, sloughing shale, le ho putlama ha sebopeho, ka ho fana ka taolo e sebetsang ea tlhoekiso le ho boloka botsitso ba seliba.
4. Keketseho ea Litefiso tsa ho Kena: Ka ho ntlafatsa thepa ea mokelikeli oa ho cheka le ho fokotsa tahlehelo ea likhohlano, PAC e sebetsang hantle e ka kenya letsoho ho sekhahla sa ho cheka ka potlako le ho boloka nako ka kakaretso ts'ebetsong ea ho cheka.
5. Tumellano ea Tikoloho le Taolo: Mekelikeli ea metsi a chekang metsi a nang le PAC e sebetsang hantle haholo a fana ka melemo ea tikoloho ho feta maro a thehiloeng ho oli, ho kenyelletsa le tšusumetso e fokolang ea tikoloho, ho lahloa ha bonolo, le ho latela litlhokahalo tsa taolo bakeng sa ts'ebetso ea ho cheka.

Likopo tsa PAC ea Ts'ebetso e Phahameng:

PAC e sebetsang hantle haholo e sebelisoa mefuteng e mengata e fapaneng ea mokelikeli oa ho cheka, ho kenyelletsa:

• Seretse se thehiloeng metsing (WBM): PAC ke karolo ea bohlokoa metsing a hloekileng, a letsoai le a nang le metsi a letsoai a sebelisoang bakeng sa mekhoa e fapaneng ea ho cheka, ho kenyeletsa ho hlahloba, ho hlahisa le ho phethoa.
• Ho chekoa ka tsela e tšekaletseng le e lebileng: PAC e thusa ho boloka botsitso le taolo ea seliba maemong a thata a ho cheka, joalo ka liliba tse fihlang nako e telele, liliba tse tšekaletseng le liliba tse khelohileng haholo.
• Ho cheka kantle ho lebopo: PAC e bohlokoa haholo ts'ebetsong ea ho cheka kantle ho naha, moo ho nahanoang ka tikoloho, mefokolo ea lisebelisoa, le botsitso ba liliba e le lintlha tsa bohlokoa.

Qetello:

Polyanionic cellulose (PAC) e sebetsang hantle haholo e bapala karolo ea bohlokoa ho maro a ho cheka a thehiloeng metsing, ho fana ka taolo ea bohlokoa ea rheological, taolo ea tahlehelo ea mokelikeli, le thepa ea botsitso ea seliba. Ka ho kenyelletsa PAC e sebetsang hantle haholo mekhoeng ea mokelikeli oa ho cheka, basebetsi ba ka finyella katleho e ntlafetseng ea ho cheka, botsitso ba hantle, le ts'ebetso e akaretsang, 'me qetellong ba tlatsetsa mesebetsing ea ho cheka e atlehileng le e bolokang chelete e ngata.
