Carboxymethyl cellulose (CMC) ke polima e qhibilihang ka metsi e nkiloeng ho selulose, e sebelisoang hangata liindastering tse fapaneng bakeng sa thepa ea eona ea ho tenya, ea botsitso le e emulsifying. High viscosity CMC (CMC-HV) ka ho khetheha e na le litšobotsi tse ikhethang tse etsang hore e be ea bohlokoa haholo lits'ebetsong tse amanang le peterole.
1. Sebopeho sa Lik'hemik'hale le Sebopeho
CMC e hlahisoa ke phetoho ea lik'hemik'hale ea cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela. Mokhoa ona o kenyelletsa ho kenngoa ha lihlopha tsa carboxymethyl (-CH2-COOH) ka mokokotlong oa cellulose, e leng se etsang hore selulose e qhibilihe ka metsing. Tekanyo ea substitution (DS), e bolelang palo e tloaelehileng ea lihlopha tsa carboxymethyl ka unit ea anhydroglucose ka molek'hule ea selulose, e susumetsa haholo thepa ea CMC. Petroleum grade high viscosity CMC hangata e na le DS e phahameng, e ntlafatsang ho qhibiliha ha eona metsing le viscosity.
2. Viscosity e phahameng
Tšobotsi e hlalosang ea CMC-HV ke viscosity ea eona e phahameng ha e qhibiliha ka metsing. Viscosity ke tekanyo ea khanyetso ea mokelikeli ho phalla, 'me viscosity e phahameng ea CMC e etsa tharollo e teteaneng, e kang gel esita le maemong a tlaase. Thepa ena e bohlokoa lits'ebetsong tsa peterole moo CMC-HV e sebelisetsoang ho fetola thepa ea rheological ea maro a ho cheka le metsoako e meng. Viscosity e phahameng e tiisa ho fanyeha ho sebetsang ha lintho tse tiileng, ho tlotsa hantle, le botsitso bo ntlafetseng ba seretse sa ho cheka.
3. Ho qhibiliha ha Metsi
CMC-HV e qhibiliha haholo metsing, e leng tlhokahalo ea bohlokoa bakeng sa tšebeliso ea eona indastering ea peterole. Ha e kenngoa ho metsoako e thehiloeng metsing, e potlakela ho nosetsa le ho qhibiliha, ho etsa tharollo e tšoanang. Ho qhibiliha hona ho bohlokoa bakeng sa ho hlophisoa hantle le ho sebelisoa ha maro a ho cheka, li-slurries tsa samente, le maro a ho qetela ts'ebetsong ea peterole.
4. Thermal Stability
Ts'ebetso ea peterole hangata e kenyelletsa tikoloho ea mocheso o phahameng, 'me botsitso ba mocheso oa CMC-HV bo bohlokoa. Sehlopha sena sa CMC se etselitsoe ho boloka viscosity le ts'ebetso ea eona tlas'a mocheso o phahameng, hangata ho fihla ho 150 ° C (302 ° F). Botsitso bona ba mocheso bo tiisa ts'ebetso e tsitsitseng mecheng ea mocheso o phahameng oa ho cheka le mekhoa ea tlhahiso, ho thibela ho senyeha le ho lahleheloa ke thepa.
5. pH botsitso
CMC-HV e bonts'a botsitso bo botle ho pholletsa le mefuta e mengata ea pH, hangata ho tloha ho 4 ho isa ho 11. Boemo bona ba pH bo bohlokoa hobane maro a chekang le metsoako e meng e amanang le peterole e ka kopana le maemo a fapaneng a pH. Ho boloka viscosity le ts'ebetso maemong a fapaneng a pH ho netefatsa katleho le ts'epahalo ea CMC-HV maemong a fapaneng a ts'ebetso.
6. Mamello ea Letsoai
Lits'ebetsong tsa petroleum, maro a atisa ho kopana le matsoai a sa tšoaneng le li-electrolyte. CMC-HV e etselitsoe ho mamella maemo a joalo, ho boloka viscosity ea eona le thepa ea ts'ebetso ka boteng ba letsoai. Mamello ena ea letsoai e molemo ka ho khetheha ho cheka ho tloha lebōpong la leoatle le mesebetsing e meng moo maemo a letsoai a leng teng.
7. Taolo ea ho sefa
E 'ngoe ea mesebetsi ea bohlokoa ea CMC-HV ho maro a ho cheka ke ho laola tahlehelo ea mokelikeli, e tsejoang hape e le taolo ea ho sefa. Ha e sebelisoa ho cheka seretse, CMC-HV e thusa ho etsa kuku e tšesaane e ke keng ea qoelisoa maboteng a sekoti, ho thibela tahlehelo e feteletseng ea mokelikeli sebopehong. Taolo ena ea ho hloekisa e bohlokoa bakeng sa ho boloka botsitso ba seliba le ho thibela tšenyo ea sebopeho.
8. Biodegradability and Environmental Impact
E le khetho e hlokolosi ea tikoloho, CMC-HV e ka senyeha 'me e tsoa mehloling e ka nchafatsoang. Biodegradability ea eona e bolela hore e senyeha ka tlhaho ha nako e ntse e ea, e fokotsa tšusumetso ea tikoloho ha e bapisoa le li-polymers tsa maiketsetso. Tšobotsi ena e ntse e le ea bohlokoa haholo kaha indasteri ea peterole e tsepamisitse maikutlo holim'a ts'ebetso le ho fokotsa mehato ea tikoloho.
9. Ho lumellana le Li-additives tse ling
Hangata CMC-HV e sebelisoa hammoho le li-additives tse ling ka maro a ho cheka le metsoako e meng ea peterole. Ho tsamaellana ha eona le lik'hemik'hale tse fapaneng, joalo ka xanthan gum, guar gum, le li-polymers tsa maiketsetso, li lumella ho etsoa ha thepa ea mokelikeli ho fihlela litlhoko tse ikhethileng tsa ts'ebetso. Ho feto-fetoha hona ho ntlafatsa ts'ebetso le katleho ea maro a ho cheka.
10. Lubricity
Mesebetsing ea ho cheka, ho fokotsa khohlano pakeng tsa khoele ea ho phunya le borehole ho bohlokoa bakeng sa ho cheka hantle le ho fokotsa ho apara. CMC-HV e kenya letsoho ho lubricity ea maro a ho cheka, ho fokotsa torque le ho hula, le ho ntlafatsa ts'ebetso e akaretsang ea ts'ebetso ea ho cheka. Lubricity ena e boetse e thusa ho lelefatsa nako ea bophelo ea lisebelisoa tsa ho cheka.
11. Ho emisoa le botsitso
Bokhoni ba ho emisa le ho tsitsisa lintho tse tiileng ka har'a maro a ho cheka a bohlokoa ho thibela ho lokisa le ho netefatsa thepa e ts'oanang ho pholletsa le mokelikeli. CMC-HV e fana ka bokhoni bo botle ba ho emisa, ho boloka thepa ea boima, li-cuttings, le lintho tse ling tse tiileng li ajoa ka ho lekana. Botsitso bona bo bohlokoa bakeng sa ho boloka thepa ea mokelikeli oa ho cheka o tsitsitseng le ho thibela mathata a ts'ebetso.
12. Kopo-Specific Melemo
Mekelikeli ea ho Epa: Mekelikeling ea ho cheka, CMC-HV e ntlafatsa ho hlaka, e laola tahlehelo ea mokelikeli, e tsitsisa sekoti, 'me e fana ka lubrication. Thepa ea eona e netefatsa ts'ebetso e nepahetseng ea ho cheka, ho fokotsa tšusumetso ea tikoloho, le ho ntlafatsa ts'ebetso e akaretsang ea sistimi ea mokelikeli oa ho cheka.
Mekelikeli ea ho Tlatsa: Ha maro a phetheloa, CMC-HV e sebelisoa ho laola tahlehelo ea mokelikeli, ho tsitsisa seliba, le ho netefatsa bots'epehi ba ts'ebetso ea ho phethela. Ho tsitsa ha eona ha mocheso le ho lumellana le lisebelisoa tse ling ho etsa hore e tšoanelehe bakeng sa ho sebelisoa ka liliba tse phahameng tsa mocheso, tse nang le khatello e phahameng.
Ts'ebetso ea Samente: Lirapeng tsa samente, CMC-HV e sebetsa joalo ka sesebelisuoa sa viscosifier le se laolang tahlehelo ea mokelikeli. E thusa ho fihlela thepa ea rheological e lakatsehang ea slurry ea samente, ho netefatsa ho beoa hantle le sete ea samente, le ho thibela ho falla ha khase le tahlehelo ea mokelikeli.
Petroleum grade high viscosity CMC (CMC-HV) ke polymer e feto-fetohang le ea bohlokoa indastering ea peterole. Litšobotsi tsa eona tse ikhethang, ho kenyelletsa le viscosity e phahameng, ho qhibiliha ha metsi, botsitso ba mocheso le pH, mamello ea letsoai, taolo ea ho sefa, biodegradability, le ho tsamaellana le li-additives tse ling, li etsa hore e be ea bohlokoa bakeng sa lits'ebetso tse fapaneng tse amanang le peterole. Ho tloha ho maro a ho cheka ho isa ho phethoa le ts'ebetso ea samente, CMC-HV e ntlafatsa ts'ebetso, ts'ebetso, le ts'ebetso ea tikoloho ea ts'ebetso ea tlhahiso ea peterole le tlhahiso. Ha indasteri e ntse e tsoela pele ho fetoha, tlhokahalo ea lisebelisoa tse sebetsang hantle, tse se nang tikoloho joalo ka CMC-HV e tla eketseha, e totobatsa karolo ea eona ea bohlokoa ts'ebetsong ea sejoale-joale ea peterole.
