Polyanionic cellulose (PAC) ke motsoako oa selulose o qhibilihang ka metsing o sebelisoang haholo indastering ea oli le khase, haholo-holo mekhoeng ea mokelikeli oa fracturing.Hydraulic fracturing, eo hangata e tsejoang e le fracking, ke mokhoa oa ho hlasimolla o sebelisoang ho eketsa ho ntšoa ha oli le khase ea tlhaho matamong a ka tlas'a lefatše.Li-PAC li bapala likarolo tse fapaneng tsa bohlokoa moralong le ts'ebetsong ea ts'ebetso ea hydraulic fracturing, e tlatsetsang katlehong, botsitsong le katlehong ka kakaretso ea ts'ebetso.
1. Kenyelletso ea polyanionic cellulose (PAC):
Polyanionic cellulose e tsoa ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela.Tlhahiso ea PAC e kenyelletsa phetoho ea lik'hemik'hale ea selulose, e hlahisang polymer ea anionic e qhibilihang ka metsing.Thepa ea eona e ikhethang e etsa hore e tšoanelehe bakeng sa mefuta e fapaneng ea likopo, ho kenyeletsoa e le motsoako oa bohlokoa ho fracturing fluid formulations.
2. Karolo ea PAC ho fracturing fluid:
Ho kenyelletsa PAC ho maro a fracturing ho ka fetola thepa ea eona ea rheological, ho laola tahlehelo ea mokelikeli, le ho ntlafatsa ts'ebetso ea mokelikeli ka kakaretso.Lintho tsa eona tse nang le mesebetsi e mengata li tlatsetsa katlehong ea hydraulic fracturing ka litsela tse ngata.
2.1 Phetoho ea 'mele:
PAC e sebetsa joalo ka rheology modifier, e amang viscosity le litšobotsi tsa phallo ea maro a robehang.Viscosity e laoloang ke ea bohlokoa bakeng sa ho fana ka mokhoa o nepahetseng, ho netefatsa hore proppant e tsamaisoa ka katleho le ho behoa ka har'a fractures e entsoeng ka har'a sebopeho sa majoe.
2.2 Taolo ea tahlehelo ea metsi:
E 'ngoe ea liqholotso tsa hydraulic fracturing ke ho thibela mokelikeli o mongata hore o se ke oa lahleheloa ke sebopeho.PAC e khona ho laola tahlehelo ea metsi ka nepo le ho etsa kuku e sireletsang filthara holim'a fracture.Sena se thusa ho boloka botsitso ba fracture, ho thibela ho kenella ka mokhoa o ts'oanelang le ho netefatsa tlhahiso e tsoelang pele hantle.
2.3 Botsitso ba mocheso:
PAC e tsitsitse mocheso, ntlha ea bohlokoa ts'ebetsong ea hydraulic fracturing, eo hangata e hlokang ho pepesehela mefuta e mengata ea mocheso.Bokhoni ba PAC ba ho boloka ts'ebetso ea eona tlas'a maemo a fapaneng a mocheso bo tlatsetsa ho ts'epahala le katleho ea ts'ebetso ea fracturing.
3. Litlhokomelo bakeng sa foromo:
Tšebeliso e atlehileng ea PAC ho maro a fracturing e hloka ho shebisisoa ka hloko litlhophiso tsa tlhahiso.Sena se kenyelletsa khetho ea sehlopha sa PAC, mahloriso, le ho tsamaellana le litlatsetso tse ling.Tšebelisano lipakeng tsa PAC le likarolo tse ling tsa mokelikeli o robehang, joalo ka li-cross-linkers le li-breaker, li tlameha ho ntlafatsoa hore li sebetse hantle.
4. Maikutlo a tikoloho le a taolo:
Ha tlhokomeliso ea tikoloho le melaoana ea hydraulic fracturing e ntse e tsoela pele ho fetoha, ts'ebeliso ea li-PAC ho maro a fracturing e lumellana le boiteko ba indasteri ba ho theha metsoako e baballang tikoloho.PAC e qhibiliha ka metsing ebile e ka senyeha, e fokotsa tšusumetso ea tikoloho le ho rarolla mathata a amanang le li-additives tsa lik'hemik'hale ho hydraulic fracturing.
5. Lithuto le lits'ebetso tsa masimong:
Lithuto tse 'maloa le lits'ebetso tsa masimong li bonts'a ts'ebeliso e atlehileng ea PAC ho hydraulic fracturing.Mehlala ena e totobatsa lintlafatso tsa ts'ebetso, ho baballa litšenyehelo le melemo ea tikoloho ea ho kenyelletsa PAC ho li-fracturing fluid formulations.
6. Mathata le tsoelopele ea kamoso:
Leha PAC e ipakile e le karolo ea bohlokoa marong a robehang, liphephetso li ntse li le joalo ka litaba tsa ho lumellana le metsi a itseng a sebopeho le tlhokeho ea lipatlisiso tse ling mabapi le litlamorao tsa bona tsa nako e telele tsa tikoloho.Lintlafatso tsa nako e tlang li ka shebana le ho rarolla mathata ana, hammoho le ho lekola mekhoa le mahlale a macha ho eketsa ts'ebetso le botsitso ba ts'ebetso ea hydraulic fracturing.
7. Qetello:
Polyanionic cellulose (PAC) e bapala karolo ea bohlokoa ho thehoeng ha maro a fracturing bakeng sa ts'ebetso ea hydraulic fracturing indastering ea oli le khase.Lintho tsa eona tse ikhethang li kenya letsoho ho laola rheology, thibelo ea tahlehelo ea mokelikeli le botsitso ba mocheso, qetellong ho ntlafatsa katleho ea ts'ebetso ea fracturing.Ha indasteri e ntse e tsoela pele ho fetoha, ts'ebeliso ea PAC e tsamaellana le menahano ea tikoloho le litlhokahalo tsa taolo, e leng se etsang hore e be karolo ea bohlokoa ntlafatsong ea mekhoa e tsitsitseng ea hydraulic fracturing.Boiteko bo ntseng bo tsoela pele ba lipatlisiso le nts'etsopele bo ka lebisa tsoelopeleng ea PAC e entsoeng ka mokelikeli oa fracturing, ho rarolla liphephetso le ho ntlafatsa ts'ebetso tlas'a maemo a fapaneng a jeoloji le a ts'ebetso.
