Sebakeng sa ts'ebetso ea ho cheka, taolo e sebetsang ea maro a ho cheka a bohlokoa bakeng sa ho netefatsa katleho le polokeho ea ts'ebetso. Mekelikeli ea ho cheka, eo hape e tsejoang e le seretse sa ho cheka, e sebeletsa merero e fapaneng ho tloha ho ho pholisa le ho tlotsa karoloana ea ho phunya ho isa ho likheo tsa ho cheka holimo le ho fana ka botsitso selibeng. Karolo e 'ngoe ea bohlokoa eo hangata e fumanoang marong a ho cheka ke Carboxymethyl Cellulose (CMC), kenyelletso e feto-fetohang e bapalang likarolo tse 'maloa tsa bohlokoa ho ntlafatseng ts'ebetso le katleho ea ts'ebetso ea ho cheka.
1. Kenyelletso ea Carboxymethyl Cellulose (CMC):
Carboxymethyl Cellulose, e atisang ho khutsufatsoa joalo ka CMC, ke polima e qhibilihang ka metsi e tsoang ho cellulose, motsoako oa tlhaho o fumanehang limela. E hlahisoa ke phetoho ea lik'hemik'hale ea selulose ka etherification, moo lihlopha tsa hydroxyl li nkeloang sebaka ke lihlopha tsa carboxymethyl (-CH2-COOH). Phetoho ena e fana ka thepa e ikhethang ho CMC, e e etsa hore e feto-fetohe haholo ebile e loketse mefuta e mengata ea lits'ebetso tsa indasteri, ho kenyeletsoa meriana, lijo, litlolo le maro a ho cheka.
2. Thepa ea CMC e Amanang le Mekelikeli ea ho Cheka
Pele o kenella ts'ebelisong ea eona ea maro a ho cheka, ho bohlokoa ho utloisisa thepa ea bohlokoa ea CMC e e etsang tlatsetso ea bohlokoa:
Ho qhibiliha ha Metsi: CMC e bonts'a ho qhibiliha ha metsi ka mokhoa o babatsehang, ho etsa litharollo tse hlakileng le tse tsitsitseng ha li kopane le metsi. Thepa ena e thusa ho kenyelletsoa habonolo mekhoeng ea mokelikeli oa ho cheka, ho etsa bonnete ba ho hasana ho tšoanang.
Taolo ea Rheological: CMC e fana ka thepa ea bohlokoa ea rheological ho maro a ho cheka, a susumetsang ponahalo ea ona, boits'oaro bo fokolang ba ho kuta, le taolo ea tahlehelo ea mokelikeli. Litšobotsi tsena li bohlokoa bakeng sa ho boloka botsitso ba seliba le ts'ebetso e nepahetseng ea ho cheka.
Taolo ea ho Filtration: CMC e sebetsa e le sesebelisoa se sebetsang sa ho sefa, se etsa kuku e tšesaane, e ke keng ea qoelisoa leboteng la seliba ho thibela tahlehelo ea mokelikeli sebopehong. Sena se thusa ho boloka li-gradients tse lakatsehang tsa khatello le ho thibela tšenyo ea sebopeho.
Botsitso ba Mocheso: CMC e bonts'a botsitso bo botle ba mocheso holim'a mefuta e mengata ea mocheso e atisang ho kopana le mesebetsi ea ho cheka. Thepa ena e tiisa ts'ebetso e tsitsitseng ea metsi a ho cheka esita le tlas'a maemo a phahameng a mocheso a kopanang le ho cheka ho tebileng.
Mamello ea Letsoai: CMC e bonts'a mamello e ntle ea letsoai, e etsa hore e be e loketseng ho sebelisoa metsing a cheka a metsi a hloekileng le a metsi a letsoai. Ho feto-fetoha hona hoa hlokahala bakeng sa ts'ebetso ea ho cheka ka mefuta e fapaneng ea jeoloji.
Tumellano ea Tikoloho: CMC e nkuoa e le botsoalle tikolohong, e ka bola, ebile e se chefo, e fokotsa tšusumetso ea eona tikolohong le ho latela litekanyetso tsa taolo bakeng sa ts'ebetso ea ho cheka.
3. Mesebetsi ea CMC ho Mekelikeli ea ho Cheka:
Ho kenyelletsoa ha CMC mekhoeng ea mokelikeli oa ho cheka ho etsa mesebetsi e 'maloa ea bohlokoa, e tlatsetsang ts'ebetsong e akaretsang, katleho, le polokeho ea ts'ebetso ea ho cheka:
Phetoho ea Viscosity: CMC e thusa ho laola viscosity ea maro a ho cheka, ka hona a susumetsa ts'ebetso ea ona ea hydraulic le bokhoni ba ho jara likheo tsa ho cheka. Ka ho lokisa mahloriso a CMC, thepa ea rheological joalo ka khatello ea lihlahisoa, matla a gel, le boits'oaro ba phallo ea mokelikeli bo ka hlophisoa ho latela litlhoko tse ikhethang tsa ho cheka.
Taolo ea Tahlehelo ea Mokelikeli: O mong oa mesebetsi ea mantlha ea CMC marong a ho cheka ke ho fokotsa tahlehelo ea mokelikeli sebopehong nakong ea ho cheka. Ka ho etsa kuku e tšesaane e tsitsitseng leboteng la seliba, CMC e thusa ho koala masoba a sebopeho, ho fokotsa tlhaselo ea mokelikeli le ho boloka botsitso ba seliba.
Ho Hloekisa Likoti le Ho Emisa: CMC e ntlafatsa thepa ea ho emisoa ea maro a ho cheka, ho thibela ho tsitsa ha likheo tsa ho cheka le lithōle botlaaseng ba seliba. Sena se ntlafatsa ts'ebetso ea ho hloekisa mekoti, ho thusa ho tlosoa ha li-cuttings ho tloha selibeng le ho thibela ho koaloa ha khoele ea ho cheka.
Lubrication and Cooling: CMC e sebetsa e le ntho e tlotsang marong a chekang, e fokotsang khohlano lipakeng tsa khoele ea ho phunya le lebota la seliba. Sena se fokotsa ho senyeha ha lisebelisoa tsa ho cheka, ho ntlafatsa ts'ebetso ea ho cheka, 'me se thusa ho tlosa mocheso o hlahisoang nakong ea ho cheka, kahoo se tlatsetsa taolong ea mocheso.
Tšireletso ea Formation: Ka ho fokotsa tlhaselo ea mokelikeli le ho boloka botsitso ba seliba, CMC e thusa ho sireletsa sebopeho ho tsoa tšenyo le ho boloka botšepehi ba eona. Sena se bohlokoa ka ho khetheha lits'ebetsong tse bonolo tse atisang ho putlama kapa ho ruruha ha motho a kopana le maro a ho cheka.
Ho tsamaellana le Li-additives: CMC e bonts'a tšebelisano e ntle haholo le mefuta e mengata e fapaneng ea li-additives tsa mokelikeli, ho kenyeletsoa matsoai, li-viscosifiers le lisebelisoa tsa boima. Ho feto-fetoha hona ho lumella hore ho thehoe mekhoa ea mokelikeli oa ho cheka o ikemiselitsoeng ho ea ka maemo a itseng a seliba le merero ea ho cheka.
4. Likopo tsa CMC ho Mechini ea Mekelikeli ea ho Epa:
Ho feto-fetoha ha maemo le katleho ea CMC e etsa hore e be tlatsetso e fumanehang hohle mefuteng e fapaneng ea litsamaiso tsa mokelikeli oa ho cheka o sebelisoang libakeng tse fapaneng tsa ho cheka:
Leretse le Thehiloeng ka Metsi (WBM): Mekelikeli e chekang e thehiloeng metsing, CMC e sebetsa e le sesebelisoa sa bohlokoa sa rheological, se laolang tahlehelo ea mokelikeli, le kenyelletso ea ho thibela shale. E thusa ho ntlafatsa botsitso ba hantle, e ntlafatsa lipalangoang tsa li-cuttings, 'me e thusa ho hloekisa mekoti ka katleho maemong a mangata a ho cheka.
Seretse se Thehiloeng ka Oli (OBM): CMC e fumana lits'ebetso ka har'a maro a chekang a thehiloeng ka oli hape, moo e sebetsang joalo ka mofetoleli oa rheology, moemeli oa taolo ea tahlehelo ea mokelikeli, le emulsifier stabilizer. Sebopeho sa eona sa ho qhibiliha ha metsi se lumella hore ho be bonolo ho kenngoa ka har'a lihlahisoa tsa seretse se entsoeng ka oli, ho fana ka ts'ebetso e ntlafetseng le ho lumellana le tikoloho.
Synthetic-based Mud (SBM): CMC e boetse e sebelisoa ka maro a ho cheka a entsoeng ka maiketsetso, moo e thusang ho ntlafatsa thepa ea rheological, taolo ea tahlehelo ea mokelikeli, le thibelo ea shale ha e ntse e netefatsa ho lumellana le oli ea maiketsetso. Sena se etsa hore litsamaiso tsa SBM li fetohe le ho sebetsa hantle maemong a thata a ho cheka.
Lisebelisoa tse Khethehileng: Ka ntle ho lisebelisoa tse tloaelehileng tsa mokelikeli, CMC e sebelisoa lits'ebetsong tse khethehileng tse kang ho cheka ka mokhoa o sa leka-lekaneng, ho cheka khatello e laoloang, le ho matlafatsa liliba. Thepa ea eona e ikhethang e etsa hore e be e loketseng ho sebetsana le mathata a itseng a amanang le maemo a thata a ho cheka, joalo ka lifensetere tse moqotetsane tsa pore le libopeho tse sa tsitsang.
Carboxymethyl Cellulose (CMC) e bapala karolo ea bohlokoa ho thehoeng le ts'ebetsong ea maro a ho cheka ho pholletsa le ts'ebetso e mengata ea ho cheka. Mehaho ea eona e ikhethang, ho kenyelletsa ho qhibiliha ha metsi, taolo ea rheological, taolo ea ho sefa, botsitso ba mocheso, le ho tsamaellana le tikoloho, e etsa hore e be tlatsetso e hlokahalang bakeng sa ho matlafatsa botsitso ba seliba, ts'ebetso ea mokelikeli le ts'ebetso e akaretsang ea ho cheka. Ho tloha seretseng se thehiloeng metsing ho ea ho litsamaiso tse thehiloeng ho oli le tsa maiketsetso, CMC e fumana lits'ebetso tse ngata, tse kenyang letsoho katlehong le polokehong ea ts'ebetso ea ho cheka ka har'a libopeho tse fapaneng tsa jeoloji le maemo a ts'ebetso. Ha mahlale a ho cheka a ntse a tsoela pele ho fetoha le mathata a ho cheka a ntse a rarahana le ho feta, bohlokoa ba CMC ho ntlafatsa ts'ebetso ea mokelikeli oa ho cheka le ho fokotsa likotsi tsa ts'ebetso e lebelletsoe ho lula e le ntho e ka sehloohong.
Ka ho utloisisa mesebetsi le ts'ebeliso ea CMC marong a ho cheka, baenjiniere ba ho cheka le basebetsi ba ka etsa liqeto tse nang le tsebo mabapi le tlhahiso ea mokelikeli, khetho ea tlatsetso, le maano a ts'ebetso, e leng se lebisang ntlafatsong ea kaho ea liliba, litšenyehelo tse fokotsehileng, le taolo e ntlafalitsoeng ea tikoloho ho oli le khase. indasteri.
