Mokelikeli oa ho cheka HEC (hydroxyethyl cellulose)

Hydroxyethyl Cellulose (HEC) ke tlatsetso e tloaelehileng e sebelisoang marong a ho cheka, a tsejoang hape e le seretse sa ho cheka, ho fetola thepa ea bona ea rheological le ho ntlafatsa ts'ebetso ea bona nakong ea ts'ebetso ea ho cheka. Mona ke kamoo HEC e sebelisoang ka teng e le motsoako oa mokelikeli oa ho cheka:

1. Taolo ea Viscosity: HEC ke polima e qhibilihang ka metsing e ka eketsang haholo viscosity ea maro a ho cheka. Ka ho lokisa boemo ba HEC ka har'a mokelikeli, li-driller li ka laola viscosity ea eona, e leng ea bohlokoa bakeng sa ho jara li-cuttings tse chekiloeng holimo le ho boloka botsitso ba seliba.
2. Taolo ea Tahlehelo ea Mokelikeli: HEC e thusa ho fokotsa tahlehelo ea mokelikeli ho tloha mokelikeli oa ho phunya ho ea sebopeho nakong ea ho cheka. Sena se bohlokoa bakeng sa ho boloka khatello e lekaneng ea hydrostatic selibeng, ho thibela tšenyo ea sebopeho, le ho fokotsa kotsi ea ho lahleheloa ke phallo ea mali.
3. Ho Hloekisa Likoti: The viscosity e ntseng e eketseha e fanoang ke HEC e thusa ho emisa likotoana tse chekiloeng le lintho tse ling tse tiileng ka har'a mokelikeli oa ho cheka, ho nolofalletsa ho ntšoa ha tsona selibeng. Sena se ntlafatsa ts'ebetso ea ho hloekisa masoba le ho fokotsa menyetla ea mathata a ho theosa joalo ka phala e khomaretsoeng kapa ho khomarela ka tsela e fapaneng.
4. Ho tsitsa ha Mocheso: HEC e bonts'a botsitso bo botle ba mocheso, ho etsa hore e loketse ho sebelisoa ha ho cheka metsi a sebetsang tlas'a maemo a mangata a mocheso. E boloka thepa ea eona ea rheological le ts'ebetso esita le ka mocheso o phahameng o kopanang le libaka tse tebileng tsa ho cheka.
5. Mamello ea Letsoai le Tšilafalo: HEC e mamella matsoai a mangata le litšila tse atisang ho fumanoa marong a ho cheka, a kang brine kapa ho cheka metsoako ea seretse. Sena se tiisa ts'ebetso e tsitsitseng le botsitso ba mokelikeli oa ho phunya esita le maemong a thata a ho cheka.
6. Ho lumellana le Lisebelisoa tse ling: HEC e lumellana le lisebelisoa tse ling tse sa tšoaneng tsa ho cheka metsi, ho akarelletsa le biocides, lubricant, shale inhibitors, le lisebelisoa tsa ho laola tahlehelo ea mokelikeli. E ka kenyelletsoa habonolo ho sebopeho sa mokelikeli oa ho cheka ho finyella thepa e lakatsehang le litšobotsi tsa ts'ebetso.
7. Mehopolo ea Tikoloho: HEC ka kakaretso e nkuoa e le botsoalle ho tikoloho ebile e se chefo. Ha e hlahise likotsi tse kholo tikolohong kapa ho basebetsi ha e sebelisoa ka nepo ts'ebetsong ea ho cheka.
8. Tekanyetso le Kopo: Tekanyo ea HEC ka maro a ho cheka a fapana ho latela lintlha tse kang viscosity e lakatsehang, litlhoko tsa taolo ea tahlehelo ea mokelikeli, maemo a ho cheka, le litšobotsi tse itseng tsa seliba. Ka tloaelo, HEC e eketsoa tsamaisong ea mokelikeli oa ho phunya 'me e kopane ka botlalo ho etsa bonnete ba ho hasana ho tšoanang pele ho sebelisoa.

HEC ke tlatsetso e feto-fetohang e bapalang karolo ea bohlokoa ho ntlafatseng ts'ebetso le botsitso ba maro a ho cheka, ho kenya letsoho ts'ebetsong e atlehileng le e atlehileng ea ho cheka indastering ea oli le khase.
