Mesebetsi ea Kereiti ea ho Cheka Oli ea Petroleum ke Efe?

Karolo ea ho cheka oli ea peterole Carboxymethyl Cellulose (CMC) e sebetsa mesebetsi e 'maloa ea bohlokoa ts'ebetsong ea ho cheka oli. Mesebetsi ea eona ea mantlha ke ena:

1. Viscosity Modifier:

CMC e sebelisoa e le mofetoleli oa viscosity ka maro a ho cheka ho laola thepa ea rheological ea mokelikeli. Ka ho lokisa mahloriso a CMC, viscosity ea mokelikeli oa ho cheka o ka etsoa ho finyella litlhoko tse khethehileng tsa ts'ebetso ea ho cheka. Taolo e nepahetseng ea viscosity e bohlokoa bakeng sa ho boloka botsitso ba hydraulic, ho thibela tahlehelo ea mokelikeli, le ho jara likheo tsa ho cheka holimo.

2. Taolo ea Tahlehelo ea Mokelikeli:

CMC e etsa kuku e tšesaane, e ke keng ea qojoa leboteng la borehole, e thusang ho laola tahlehelo ea mokelikeli sebopehong nakong ea ho cheka. Keke ena ea sefa e sebetsa e le tšitiso, e fokotsa kotsi ea ho se tsitse ha wellbore, tšenyo ea sebopeho, le ho lahleheloa ke phallo ea mali. CMC e tiisa ka nepo libopeho le likheo tse ka kenang, e netefatsa ts'ebetso e nepahetseng ea ho cheka.

3. Ho Suspension le Shale Thibelo:

CMC e thusa ho emisa le ho jara likotoana tsa boro le likaroloana tse ling tse tiileng holimo, ho thibela ho lula le ho bokellana ha tsona ka tlase ho sekoti. E boetse e thibela ho phalla le ho hasana ha libopeho tsa shale, ho fokotsa kotsi ea phala e khomaretsoeng, ho se tsitse ha wellbore, le tšenyo ea sebopeho. CMC e ntlafatsa ts'ebetso e akaretsang le polokeho ea ts'ebetso ea ho cheka ka ho boloka botsitso ba metsi le ho fokotsa nako ea ho theoha.

4. Phokotso ea Lubrication le Friction:

CMC e sebetsa joalo ka setlolo ho maro a ho cheka, ho fokotsa khohlano lipakeng tsa khoele ea ho phunya le lebota la borehole. Sena se fokotsa torque le ho hula khoeleng ea ho cheka, ho ntlafatsa ts'ebetso ea ho cheka le ho fokotsa ho senyeha ha lisebelisoa tsa ho cheka. CMC e boetse e ntlafatsa ts'ebetso ea li-motor tse tlase le lisebelisoa tsa ho cheka ka rotary ka ho fokotsa likhohlano le ho hlahisa mocheso.

5. Mocheso le Botsitso ba Letsoai:

CMC e bonts'a botsitso bo botle ba mocheso le letsoai, e etsa hore e loketse ho sebelisoa libakeng tse fapaneng tsa ho cheka, ho kenyeletsoa maemo a mocheso o phahameng le a letsoai le phahameng. E boloka thepa ea eona ea rheological le matla a ho laola tahlehelo ea mokelikeli esita le tlas'a maemo a tlaase a tlaase, ho netefatsa ts'ebetso e tsitsitseng le ho tšepahala mesebetsing e thata ea ho cheka.

6. E Sekehelang Tikoloho:

CMC e na le botsoalle ba tikoloho ebile e khona ho bola, 'me e etsa hore e tšoanelehe bakeng sa ho sebelisoa libakeng tseo ho chekoang ho tsona tse nang le bothata ba tikoloho. Ha e na li-additives tse kotsi kapa lik'hemik'hale tse chefo, tse fokotsang tšusumetso ho tikoloho e potolohileng le mehloli ea metsi a ka tlas'a lefatše. Mekelikeli ea ho cheka e thehiloeng ho CMC e lumellana le melao le litekanyetso tsa tikoloho, ho netefatsa mekhoa e tsitsitseng ea ho cheka.

Ka kakaretso, boemo ba ho cheka oli ea petroleum Carboxymethyl Cellulose (CMC) bo fana ka mesebetsi e 'maloa ea bohlokoa marong a ho cheka, ho kenyelletsa le phetoho ea viscosity, taolo ea tahlehelo ea mokelikeli, ho emisoa le ho thibela shale, phokotso le khohlano, mocheso le botsitso ba letsoai, le botsoalle ba tikoloho. Thepa ea eona e feto-fetohang e kenya letsoho ts'ebetsong, polokehong le ts'ebetsong ea ts'ebetso ea ho cheka oli le khase lefats'eng ka bophara.
