Petroleum Grade Carboxymethyl Cellulose (CMC) ke k'hemik'hale ea bohlokoa e sebelisoang indastering ea oli le khase, haholo-holo marong a ho cheka. Lebitso "LV" le emetse "Low Viscosity," ho bonts'a thepa ea eona e ikhethang le ho tšoaneleha bakeng sa lits'ebetso tse ikhethileng ka har'a ho ntšoa le ho sebetsa ha peterole.
Sebopeho le Thepa ea Petroleum Kereiti ea CMC-LV
Carboxymethyl Cellulose ke polymer e qhibilihang ka metsing e tsoang ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Phapang ea "viscosity e tlaase" e na le thepa e ikhethang, ho kenyelletsa le boima bo tlaase ba molek'hule, bo fetolelang ho ba le phello e tlaase e teteaneng ha e qhibiliha ka metsing. Sena se etsa hore e be se loketseng bakeng sa lits'ebetso tse hlokang liphetoho tse nyane ho viscosity ea mokelikeli.
Lintlha tsa Bohlokoa:
Solubility: Ho qhibiliha ho hoholo metsing, ho nolofatsa ho tsoakana le ho ajoa habonolo ka har'a maro a chekang.
Thermal Stability: E boloka botšepehi bo sebetsang tlas'a mocheso o phahameng o kopanang nakong ea ho cheka.
Mamello ea pH: E tsitsitse maemong a fapaneng a pH, e etsa hore e feto-fetohe bakeng sa libaka tse fapaneng tsa ho cheka.
Low Viscosity: Tšusumetso e fokolang ho viscosity ea mokelikeli oa motheo, oa bohlokoa bakeng sa maemo a khethehileng a ho cheka.
Tšebeliso ea Petroleum Grade CMC-LV
1. Mekelikeli ea ho Cheka
Tšebeliso e ka sehloohong ea Petroleum Grade CMC-LV ke ho etsoa ha maro a ho cheka, a tsejoang hape e le seretse. Mekelikeli ena e bohlokoa haholo ts'ebetsong ea ho cheka ka mabaka a 'maloa:
Lubrication: Mekelikeli e chekang e tlotsa karolo ea boro, e fokotsa ho hohlana le ho senyeha.
Ho pholisa: Li thusa ho pholisa karolo ea ho phunya le khoele ea ho phunya, ho thibela mocheso o feteletseng.
Taolo ea Khatello: Mekelikeli ea ho cheka e fana ka khatello ea hydrostatic ho thibela ho phatloha le ho tsitsisa seliba.
Ho tlosoa ha li-Cuttings: Li tsamaisa li-cutlets tsa li-drill holimo, li boloka tsela e hlakileng ea ho cheka.
Tabeng ena, viscosity e tlaase ea CMC-LV e tiisa hore mokelikeli oa ho cheka o lula o pompa 'me o ka phethahatsa mesebetsi ena ka katleho ntle le ho ba motenya haholo kapa oa gelatinous, o ka sitisang ho potoloha le ho cheka hantle.
2. Tahlehelo ea Mokelikeli
Taolo ea tahlehelo ea metsi e bohlokoa ts'ebetsong ea ho cheka ho thibela tahlehelo ea maro a ho cheka sebopeho. Petroleum Grade CMC-LV e sebetsa e le ntho e laolang tahlehelo ea mokelikeli ka ho etsa kuku e tšesaane, e sa khoneng ho phunyeletsa maboteng a seliba. Tšitiso ena e fokotsa ho kenella ha maro a ho cheka ka har'a mafika a pota-potileng, ka tsela eo ho boloka botšepehi ba seliba le ho thibela tšenyo e ka bang teng ea sebopeho.
3. Ho matlafatsa Botsitso ba Borehole
Ka ho kenya letsoho ho thehoeng ha kuku e tsitsitseng ea sefe, CMC-LV e thusa ho boloka botsitso ba metsi. Sena ke sa bohlokoa ka ho khetheha mekhoeng e atisang ho ba le botsitso kapa ho oa. Keke ea sefene e tšehetsa marako a seliba 'me e thibela ho thella kapa ho phunya, ho fokotsa kotsi ea tieho ea ts'ebetso le litšenyehelo tse ling tse amanang le ho se tsitse ha metsi.
4. Corrosion Inhibition
Petroleum Grade CMC-LV le eona e ka bapala karolo ea ho thibela kutu. Ka ho laola tahlehelo ea mokelikeli le ho boloka tikoloho e tsitsitseng ka har'a seliba, CMC-LV e thusa ho sireletsa lisebelisoa tsa ho cheka linthong tse senyang tse teng sebopehong kapa tse hlahisoang ka maro a ho cheka. Sena se eketsa nako ea bophelo ba lisebelisoa tsa ho cheka le ho fokotsa litšenyehelo tsa tlhokomelo.
Melemo ea ho Sebelisa Kereiti ea Petroleum CMC-LV
1. Katleho ea Ts'ebetso
Tšebeliso ea CMC-LV marong a ho cheka e ntlafatsa haholo ts'ebetso ea ts'ebetso. Viscosity ea eona e tlaase e tiisa hore mokelikeli o lula o khona ho laola le ho sebetsa maemong a fapaneng a ho cheka, ho nolofatsa ts'ebetso e bonolo le ho fokotsa nako ea ho theoha.
2. Litšenyehelo-Ka katleho
Ka ho thibela tahlehelo ea mokelikeli le ho boloka botsitso ba seliba, CMC-LV e thusa ho fokotsa nako e sa hlahiseng tlhahiso le litšenyehelo tse amanang. E fokotsa tlhokahalo ea lisebelisoa tse eketsehileng le mehato ea ho sebetsana le tahlehelo ea mokelikeli kapa ho se tsitse ha borehole, ho fella ka ho boloka litšenyehelo ka kakaretso.
3. Tšusumetso ea Tikoloho
Petroleum Grade CMC-LV e nkiloe ho cellulose, mohloli oa tlhaho le o ka nchafatsoang. Tšebeliso ea eona mekelikeli ea ho cheka e ka kenya letsoho mekhoeng ea ho cheka e baballang tikoloho. Ho feta moo, taolo e sebetsang ea tahlehelo ea mokelikeli e fokotsa monyetla oa tšilafalo ea tikoloho ho tsoa ho maro a cheka a kenang sebopeho.
4. Ntlafatso ea Tšireletseho
Ho boloka botsitso ba seliba le ho laola tahlehelo ea mokelikeli ke tsa bohlokoa bakeng sa ts'ebetso e sireletsehileng ea ho cheka. CMC-LV e thusa ho thibela ho phatloha, ho putlama ha liliba, le maemo a mang a kotsi, ho netefatsa polokeho ea basebetsi le lisebelisoa.
Lisebelisoa tse Ntle ho Mekelikeli ea ho Cheka
Leha ts'ebeliso ea mantlha ea Kereiti ea Petroleum CMC-LV e le marong a ho cheka, e na le ts'ebeliso e 'ngoe ka har'a indasteri ea peterole le ho feta.
1. Ts'ebetso ea ho tiisa
Ts'ebetsong ea samente, CMC-LV e ka sebelisoa ho fetola thepa ea li-slurries tsa samente. E thusa ho laola tahlehelo ea mokelikeli le ho ntlafatsa thepa ea rheological ea slurry, ho netefatsa mosebetsi oa samente o sebetsang hantle le o tšoarellang.
2. Ntlafatso ea Oli e Ntlafetseng (EOR)
CMC-LV e ka sebelisoa mekhoeng e Ntlafetseng ea Pholiso ea Oli, moo thepa ea eona e thusang ho ntlafatsa motsamao oa maro a entetsoeng, ho ntlafatsa ts'ebetso ea ho hlaphoheloa.
3. Hydraulic Fracturing
Ka hydraulic fracturing, CMC-LV e ka ba karolo ea sebopeho sa mokelikeli oa fracturing, moo e thusang ho laola tahlehelo ea mokelikeli le ho boloka botsitso ba fractures e entsoeng.
Petroleum Grade CMC-LV ke khemikhale e feto-fetohang le ea bohlokoa indastering ea oli le khase, e sebelisoang haholo marong a ho cheka ho ntlafatsa ts'ebetso, polokeho le ts'ireletso ea tikoloho. Mehaho ea eona e ikhethang, joalo ka viscosity e tlase, ho qhibiliha ho holimo, le botsitso ba mocheso, e etsa hore e be ea bohlokoa haholo bakeng sa taolo ea tahlehelo ea mokelikeli, botsitso ba metsi le ho thibela kutu. Ntle le maro a ho cheka, ts'ebeliso ea ona ho samente, ho khutlisa oli e ntlafalitsoeng, le ho robeha ha hydraulic ho totobatsa bohlokoa ba eona. Ha indasteri e ntse e tsoela pele ho batla litharollo tse sebetsang hantle le tse baballang tikoloho, karolo ea Petroleum Grade CMC-LV e kanna ea hola, e tiisa boemo ba eona e le karolo ea bohlokoa mekhoeng ea sejoale-joale ea boenjiniere ba peterole.
