Taolo ea Tahlehelo ea Mokelikeli ka Hydroxyethyl Cellulose (HEC) Ts'ebetsong ea ho Cheka
Indastering ea oli le khase, ho boloka botsitso ba wellbor ho bohlokoa bakeng sa ts'ebetso e sebetsang hantle ea ho cheka. Mokhoa o mong o sebetsang oa ho finyella sena ke ka ho sebelisa Hydroxyethyl Cellulose (HEC) marong a ho cheka ho laola tahlehelo ea mokelikeli libakeng tse ka kenang metsi.
Ho Utloisisa Tahlehelo ea Mokelikeli ho Chekeng
Tahlehelo ea mokelikeli e etsahala ha maro a ho tjheka a kenella mafikeng a potolohileng nakong ea ho tjheka. Ho tjheka hona ho ka lebisa mathateng a 'maloa, ho kenyeletsoa:
- Ho se tsitse ha Wellbore: Ho lahleheloa ke mokelikeli ho ka etsa hore seliba se putlame kapa se se ke sa tsitsa.
- Tšenyo ea Sebopeho: Tahlehelo e feteletseng ea mokelikeli e ka senya sebopeho, ea ama tlhahiso ea nakong e tlang.
- Litšenyehelo tse Eketsehileng tsa Ts'ebetso: Ho laola le ho lefella tahlehelo ea mokelikeli ho ka lebisa litšenyehelong tse phahameng tsa ts'ebetso.
Karolo ea HEC Taolong ea Tahlehelo ea Metsi
Hydroxyethyl Cellulose (HEC) ke polymer e qhibilihang ka metsing e sebelisoang haholo marong a ho tjheka bakeng sa thepa ea eona ea rheological. Mesebetsi ea eona ea mantlha taolong ea tahlehelo ea mokelikeli e kenyelletsa:
- Sebopeho sa Sefa sa Kaka: HEC e thusa ho theheng kuku e tšesaane, e sa keneng metsi maboteng a liliba. Kuku ena ea sefe e sebetsa e le thibelo, e fokotsa bongata ba mokelikeli oa ho phunya o kenang sebopehong.
- Ntlafatso ea ho hlaka ha mahlo: Ka ho eketsa ho teteana ha mokelikeli oa ho tjheka, HEC e ntlafatsa ho emisoa ha li-drill cut le ho thusa ho boloka khatello e hlokahalang ea hydraulic. Ho teteana hona ho ntlafalitsoeng ho boetse ho thusa ho theheng kuku ea sefe e sebetsang hantle haholoanyane.
- Botsitso ba Wellbore: Motsoako oa tahlehelo e fokotsehileng ea mokelikeli le ho ntlafala ha viscosity ho tlatsetsa botsitsong ba wellbor ka kakaretso, ho fokotsa kotsi ea ho putlama ha wellbor le tšenyo ea ho thehoa ha eona.
Melemo ea ho Sebelisa HEC bakeng sa Taolo ea Tahlehelo ea Metsi
Ho kenyelletsa HEC ka har'a maro a ho cheka ho fana ka melemo e 'maloa:
- Ho Sebetsa ka Botlalo Litšenyehelo: HEC e sebetsa hantle ha ho na le maemo a tlase a ho tjheka, e leng se thusang ho fokotsa ditjeo tsa mokelikeli wa ho tjheka.
- Ho lumellana ha Tikoloho: HEC e nkiloe mehloling ea cellulose e nchafatsoang 'me e nkoa e le mosa tikolohong. Tšebeliso ea eona marong a ho cheka e thusa ho fokotsa tšusumetso ea tikoloho ea ts'ebetso ea ho cheka.
- Ho lumellana le Li-Additives: HEC e tsamaisana le mefuta e mengata ea li-additi tsa mokelikeli oa ho cheka, ho kenyeletsoa le li-weighting agents, li-viscosifier le li-lubricant. E ka kenyelletsoa habonolo mefuteng ea mokelikeli oa ho cheka ho fihlela litšobotsi tse lakatsehang tsa ts'ebetso le ho rarolla liphephetso tse itseng tsa ho cheka.
Qetello
Ho kenyelletsa Hydroxyethyl Cellulose (HEC) ho kenya metsi a chekang ke leano le sebetsang la ho laola tahlehelo ea mokelikeli le ho boloka botsitso ba seliba. Bokhoni ba eona ba ho etsa kuku ea sefe e sa keneng metsi, ho ntlafatsa viscosity, le ho kenya letsoho botšepehing ba seliba ka kakaretso bo e etsa karolo ea bohlokoa ts'ebetsong ea ho cheka. Ka ho sebelisa melemo ea HEC, basebetsi ba ka fihlela mekhoa ea ho cheka e sebetsang hantle le e theko e tlaase.
Bakeng sa tlhahisoleseding e batsi mabapi le ditshebediso le melemo ya HEC marong a ho tjheka, nahana ka ho hlahloba mehlodi e kang Selulose ea Kingmax.
