Hydroxyl Ethyl Cellulose| HEC - Mekelikeli ea ho Cheka Oli

Hydroxyethylcellulose (HEC) ke karolo ea bohlokoa marong a ho cheka oli, e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le katleho ea ts'ebetso ea ho cheka. Tataisong ena e felletseng, re tla hlahloba thepa ea HEC, ts'ebeliso ea eona marong a ho cheka oli, melemo eo e fanang ka eona, le phello ea eona ts'ebetsong ea ho cheka.

Selelekela ho HEC:

Hydroxyethylcellulose (HEC) ke polima e qhibilihang ka metsing e tsoang ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Ka phetoho ea lik'hemik'hale, lihlopha tsa hydroxyethyl li hlahisoa mokokotlong oa cellulose, li fana ka thepa e ikhethang ho polymer. HEC e sebelisoa haholo liindastering tse sa tšoaneng, ho akarelletsa le meriana, lihlahisoa tsa tlhokomelo ea botho, thepa ea kaho, le maro a ho cheka oli.

Thepa ea HEC:

HEC e bonts'a thepa e 'maloa e e etsang hore e loketse ho sebelisoa marong a ho cheka oli:

1. Ho qhibiliha ha Metsi: HEC e qhibiliha haholo ka metsing, e lumellang hore ho be bonolo ho kenngoa ka har'a metsoako ea mokelikeli oa ho cheka ka metsi.
2. Ho teteana: HEC e sebetsa e le ntho e teteaneng, e eketsang ponahalo ea metsi a ho cheka le ho fana ka ho emisoa ho molemo ha li-drill cuttings.
3. Taolo ea Tahlehelo ea Mokelikeli: HEC e etsa kuku e tšesaane, e ke keng ea qoelisoa maboteng a seliba, e fokotsa tahlehelo ea mokelikeli sebopehong.
4. Botsitso ba Mocheso: HEC e boloka thepa ea eona ea rheological le katleho ea ho laola tahlehelo ea mokelikeli holim'a mefuta e mengata ea mocheso e kopanang le eona nakong ea ts'ebetso ea ho cheka.
5. Mamello ea Letsoai: HEC e mamella matsoai a mangata le matsoai a mangata, e leng se etsang hore e tšoanelehe ho sebelisoa metsing a letsoai kapa maro a ho cheka a brine.

Likopo tsa HEC ho Mekelikeli ea ho Cheka Oli:

HEC e sebetsa mesebetsi e 'maloa ea bohlokoa marong a ho cheka oli:

1. Taolo ea Rheology: HEC e sebelisetsoa ho lokisa thepa ea rheological ea maro a ho cheka, ho kenyelletsa le viscosity, matla a gel le ntlha ea tlhahiso. Ka ho laola rheology, HEC e netefatsa ho hloekisoa ha sekoti hantle, botsitso ba seliba, le khatello ea hydraulic bakeng sa ho cheka hantle.
2. Taolo ea Tahlehelo ea Mokelikeli: HEC e etsa kuku e tšesaane, e ke keng ea qoelisoa maboteng a seliba, e fokotsa tahlehelo ea mokelikeli sebopehong. Sena se thusa ho boloka botsitso ba hantle, ho thibela tšenyo ea sebopeho, le ho fokotsa kotsi ea ho khomarela ka tsela e fapaneng.
3. Shale Inhibition: HEC e thibela metsi le ho ruruha ha libopeho tsa shale tse kopaneng nakong ea ts'ebetso ea ho cheka. Ka ho theha mokoallo o sireletsang holim'a metsi a shale, HEC e thusa ho thibela ho phalla ha metsi le ho boloka botsitso ba wellbore maemong a thata a ho cheka.
4. Ho tsitsa ha Mocheso: HEC e boloka thepa ea eona ea rheological le katleho ea taolo ea tahlehelo ea mokelikeli holim'a mefuta e mengata ea mocheso, e etsa hore e loketse ho sebelisoa libakeng tse peli tsa mocheso le mocheso o tlaase oa ho cheka.
5. Mamello ea Letsoai: HEC e mamella matsoai a mangata le matsoai a teng ka har'a maro a ho cheka, ho netefatsa botsitso le ts'ebetso ts'ebetsong ea metsi a letsoai kapa a brine.

Melemo ea ho Sebelisa HEC ho Mekelikeli ea ho Cheka Oli:

Tšebeliso ea HEC marong a ho cheka oli e fana ka melemo e mengata:

1. Katleho e Ntlafetseng ea ho cheka: HEC e ntlafatsa thepa ea rheological ea metsi a ho cheka, ho netefatsa hore ho hloekisoa ha mekoti ka mokhoa o nepahetseng, botsitso ba hantle, le taolo ea khatello ea metsi.
2. Tšenyo e Fokotsoeng ea Sebopeho: Ka ho etsa kuku e ke keng ea qojoa, HEC e thusa ho fokotsa tahlehelo ea mokelikeli ka har'a sebopeho, ho fokotsa kotsi ea tšenyo ea sebopeho le ho boloka botšepehi ba polokelo.
3. Botsitso bo Ntlafetseng ba Wellbore: HEC e thibela ho phalla ha shale le ho ruruha, ho boloka botsitso ba hantle le ho thibela ho putlama ha hantle kapa ho se tsitse.
4. Ho feto-fetoha ha maemo: HEC e lumellana le mefuta e mengata ea li-additives tsa mokelikeli oa ho cheka 'me e ka sebelisoa mefuteng e sa tšoaneng ea maro a ho cheka, ho akarelletsa le metsi a thehiloeng metsing, a oli le a maiketsetso.
5. Katleho ea Litšenyehelo: HEC ke tlatsetso e bolokang chelete e ngata ha e bapisoa le liphetoho tse ling tsa rheology le li-agents tsa ho laola tahlehelo ea mokelikeli, tse fanang ka ts'ebetso e babatsehang ka litšenyehelo tse utloahalang.

Lintlha tsa ho Sebelisa HEC ho Mekelikeli ea ho Cheka Oli:

Leha HEC e fana ka melemo e mengata, ho na le lintlha tse ling tseo u lokelang ho li hopola:

1. Mahloriso a Molemo ka ho Fetisisa: Motsoako o nepahetseng oa HEC mekhoeng ea mokelikeli oa ho cheka o ka fapana ho latela maemo a itseng a ho cheka, sebopeho sa mokelikeli, le litšobotsi tse lakatsehang tsa ts'ebetso.
2. Ho lumellana: HEC e lokela ho lumellana le lisebelisoa tse ling le lik'hemik'hale tse teng ka mokelikeli oa ho phunya ho netefatsa botsitso le ts'ebetso.
3. Taolo ea Boleng: Ho bohlokoa ho sebelisa lihlahisoa tsa boleng bo holimo tsa HEC ho tsoa ho bafani ba thepa ba tšepahalang ho netefatsa ts'ebetso e ts'oanang, e ts'eptjoang, le ts'ebetso ea ho cheka metsoako ea mokelikeli.
4. Mehopolo ea Tikoloho: Ho lahloa ka nepo ha maro a ho cheka a nang le HEC ke habohlokoa ho fokotsa tšusumetso ea tikoloho le ho lumellana le litlhoko tsa taolo.

Qetello:

Hydroxyethylcellulose (HEC) e bapala karolo ea bohlokoa marong a ho cheka oli, ho fana ka taolo ea rheology, taolo ea tahlehelo ea mokelikeli, thibelo ea shale, botsitso ba mocheso le mamello ea letsoai. Mehaho le melemo ea eona e feto-fetohang e etsa hore e be tlatsetso e hlokahalang mekhoeng ea mokelikeli oa ho cheka, e tlatsetsang ntlafatsong e ntlafetseng ea ho cheka, botsitso ba seliba, le ts'ebetso ea ho cheka ka kakaretso. Ka ho utloisisa thepa, lits'ebetso, melemo, le menahano ea HEC marong a ho cheka oli, litsebi tsa ho cheka li ka ntlafatsa metsoako ea mokelikeli le ho ntlafatsa ts'ebetso ea ho cheka libakeng tse fapaneng tsa oli.
