Selulose ea Hydroxyethyl ka Mokelikeling o Fehlang ka ho Cheka Oli

Hydroxyethyl cellulose (HEC) ka nako e 'ngoe e sebelisoa mokelikeli oa fracturing o sebelisoang ts'ebetsong ea ho cheka oli, haholo-holo ho hydraulic fracturing, e tsejoang ka hore ke fracking.Mekelikeli ea fracturing e kenngoa ka har'a seliba ka khatello e phahameng ho etsa fractures ka har'a mafika, e leng se lumellang ho ntšoa ha oli le khase.Mona ke kamoo HEC e ka sebelisoang ka har'a maro a fracturing:

1. Viscosity Modification: HEC e sebetsa e le rheology modifier, e thusang ho laola viscosity ea fracturing fluid.Ka ho fetola mahloriso a HEC, basebetsi ba ka fetola viscosity ho finyella thepa e lakatsehang ea mokelikeli oa fracturing, ho netefatsa hore ho tsamaisoa hantle ha metsi le ho thehoa ha fracture.
2. Taolo ea Tahlehelo ea Mokelikeli: HEC e ka thusa ho laola tahlehelo ea mokelikeli ka har'a sebopeho nakong ea hydraulic fracturing.E etsa kaka e tšesaane e ke keng ea qojoa maboteng a ho robeha, ho fokotsa tahlehelo ea mokelikeli le ho thibela tšenyo ea sebopeho.Sena se thusa ho boloka botsitso ba fracture le ho netefatsa ts'ebetso e nepahetseng ea polokelo.
3. Proppant Suspension: Hangata metsi a fracturing a na le lisebelisoa, tse kang lehlabathe kapa likaroloana tsa ceramic, tse kenngoa ka har'a fractures ho li boloka li bulehile.HEC e thusa ho emisa li-proppants tsena ka har'a mokelikeli, ho thibela ho lula ha tsona le ho netefatsa ho ajoa ka mokhoa o ts'oanang ka har'a fractures.
4. Fracture Cleanup: Ka mor'a ts'ebetso ea fracturing, HEC e ka thusa ho hloekisa mokelikeli oa fracturing ho tloha selibeng le marang-rang a fracture.Viscosity ea eona le thepa ea ho laola tahlehelo ea mokelikeli e thusa ho netefatsa hore mokelikeli o robehileng o ka khutlisoa hantle selibeng, e leng se lumellang tlhahiso ea oli le khase ho qala.
5. Ho lumellana le Li-additives: HEC e lumellana le li-additives tse fapa-fapaneng tse atisang ho sebelisoa mekelikeli ea fracturing, ho akarelletsa le biocides, corrosion inhibitors, le li-reducers tsa friction.Ho lumellana ha eona ho lumella ho etsoa ha maro a qhekellang a ikhethileng a lumellanang le maemo a itseng a seliba le litlhoko tsa tlhahiso.
6. Temperature Stability: HEC e bonts'a botsitso bo botle ba mocheso, e etsa hore e loketse ho sebelisoa ka maro a fracturing a pepesehileng mocheso o phahameng o tlase.E boloka thepa ea eona ea rheological le katleho e le motsoako oa mokelikeli tlas'a maemo a feteletseng, ho netefatsa ts'ebetso e tsitsitseng nakong ea ts'ebetso ea hydraulic fracturing.

Hydroxyethyl cellulose (HEC) e ka bapala karolo ea bohlokoa ho thehoeng ha maro a fracturing bakeng sa lits'ebetso tsa ho cheka oli.Phetoho ea viscosity ea eona, taolo ea tahlehelo ea mokelikeli, ho emisoa ka mokhoa o ts'oanelang, ho lumellana le li-additives, botsitso ba mocheso, le thepa e 'ngoe e kenya letsoho katlehong le katlehong ea ts'ebetso ea hydraulic fracturing.Leha ho le joalo, ke habohlokoa ho nahana ka litšobotsi tse khethehileng tsa letamo le maemo a seliba ha ho etsoa metsoako ea mokelikeli oa fracturing e nang le HEC.
