Hydroxyethyl Cellulose (HEC) ke polima e qhibilihang ka metsing e sebelisoang haholo ts'ebetsong ea ho cheka oli. Thepa ea eona e ikhethang ea 'mele le ea lik'hemik'hale e e fa melemo e mengata tšimong ena.
1. Ntlafatso ea thepa ea rheological
Selulose ea Hydroxyethyl e na le thepa e ntle ea ho tenya 'me e ka eketsa viscosity ea mokelikeli oa ho cheka haholo. Thepa ena e bohlokoa ka ho khetheha nakong ea ho cheka, kaha maro a phahameng a viscosity a ka emisang li-cutlets tsa ho cheka le ho li thibela ho beha ka tlase ho seliba kapa leboteng la liphaephe, ka hona ho ntlafatsa ts'ebetso ea ho cheka le polokeho. Boitšoaro ba pseudoplastic ba litharollo tsa HEC bo fella ka ho fokotseha ha viscosity ka litekanyetso tse phahameng tsa ho kuta (joaloka haufi le drill bit), e fokotsang khohlano le matla a ho pompa, le viscosity e phahameng ka litekanyetso tse tlaase tsa ho kuta (joaloka haufi le lebota la seliba), e thusang Bakeng sa ho jara. le ho emisa likheo tsa ho cheka.
2. Thepa ea metsi le ho boloka metsi
Hydroxyethyl cellulose e na le thepa e ntle haholo ea hydration mme e ka qhibiliha kapele ka metsing ebe e etsa tharollo e ts'oanang. Ts'ebetso ena e thusa ho lokisoa ka potlako le ho lokisoa ha metsoako ea mokelikeli oa ho cheka sebakeng sa marang-rang, e eketsang maemo a ts'ebetso. Ho phaella moo, HEC e boetse e na le thepa e matla ea ho boloka metsi, e ka fokotsang mouoane le tahlehelo ea metsi ka maro a ho cheka le ho boloka botsitso le katleho ea maro a ho cheka. Haholo-holo mocheso o phahameng le maemo a khatello e phahameng, thepa ea eona ea ho boloka metsi e bohlokoa haholo.
3. Sefa taolo
Nakong ea ts'ebetso ea ho cheka, tahlehelo ea mokelikeli oa mokelikeli oa ho phunya ke parameter ea bohlokoa. Tahlehelo e feteletseng ea ho sefa e tla lebisa keketsehong ea botenya ba kuku ea seretse, e tla lebisa mathateng a joalo ka ho se tsitse ha lebota le ho lutla ha seliba. Hydroxyethyl cellulose e ka fokotsa ka nepo tahlehelo ea mokelikeli oa maro a ho cheka, ea etsa kuku e teteaneng ea sefa, ea fokotsa kotsi ea ho lutla le ho putlama ha lebota la seliba, le ho ntlafatsa botsitso ba lebota la seliba. Ntle le moo, HEC e ka boloka ts'ebetso e tsitsitseng tlasa litekanyetso tse fapaneng tsa pH le maemo a mahloriso a electrolyte le ho ikamahanya le maemo a fapaneng a rarahaneng a jeoloji.
4. Eco-friendly
Ha melao ea tikoloho e ntse e thatafala le ho feta, tlhokahalo ea maro a chekang tikoloho le eona ea eketseha. Joaloka motsoako oa tlhaho oa cellulose, hydroxyethyl cellulose e na le biodegradability e ntle 'me e na le tšusumetso e fokolang tikolohong. Ha ho bapisoa le li-polymer tse ling tsa maiketsetso, tšebeliso ea HEC e fokotsa mesi e kotsi 'me e thusa ho finyella lipakane tsa ho cheka tse tala. Ho phaella moo, tlhaho e se nang chefo le e se nang kotsi ea HEC e boetse e fokotsa likotsi tse ka 'nang tsa e-ba teng ho bophelo bo botle ba basebetsi.
5. Tsa moruo
Leha theko ea hydroxyethyl cellulose e batla e phahame, ts'ebetso ea eona e ntle haholo nakong ea ts'ebeliso e ka fokotsa litšenyehelo tse akaretsang nakong ea ts'ebetso ea ho cheka. Ntlha ea pele, thepa ea HEC e sebetsang hantle ea ho tiisa le ho boloka metsi e fokotsa palo ea mokelikeli oa ho cheka le litšenyehelo tsa thepa. Ntlha ea bobeli, botsitso le botšepehi ba HEC bo fokotsa kotsi ea ho hlōleha ka tlas'a lefatše le ho koala ho sa reroang, ho fokotsa litšenyehelo tsa tlhokomelo le ho lokisa. Qetellong, thepa ea HEC e baballang tikoloho e fokotsa litšenyehelo tsa ho lahloa ha litšila le ho ipapisa le tikoloho.
6. Ho lumellana le ho Fetolana
Hydroxyethyl cellulose e na le botsitso bo botle ba lik'hemik'hale le ho lumellana ho pharaletseng, 'me e ka lumellana le mefuta e sa tšoaneng ea li-additives le mekhoa ea ho cheka metsi ho theha tsamaiso e kopanetsoeng e nang le mesebetsi e itseng. Mohlala, HEC e ka sebelisoa mmoho le liente tse thibelang ho putlama, liente tse thibelang ho dutla le mafura ho ntlafatsa tšebetso e felletseng ea maro a ho cheka le ho fihlela maemo a fapaneng a jeoloji le litlhoko tsa ho cheka. Ho phaella moo, HEC e ka boela ea sebelisoa lik'hemik'hale tse ling tsa oli tse kang ho tlatsa metsi le maro a fracturing, ho bontša ho feto-fetoha ha eona.
Hydroxyethyl cellulose e na le melemo e mengata ea ho cheka oli, haholo-holo e bonts'itsoeng ho ntlafatsa thepa ea rheological, ho eketsa matla a metsi le ho boloka metsi, ho laola ka katleho molumo oa ho hloekisa, ho ba le botsoalle ba tikoloho, moruo le mesebetsi e mengata. Melemo ena e etsa hore HEC e be tlatsetso ea bohlokoa le ea bohlokoa ts'ebetsong ea ho cheka oli, e thusang ho fihlela ts'ebetso ea ho cheka e sebetsang hantle, e bolokehileng le e se nang tikoloho. Ka tsoelopele e tsoelang pele ea thekenoloji le ho teba ha ts'ebeliso, litebello tsa ts'ebeliso ea hydroxyethyl cellulose ho cheka oli e tla ba kholo.
