Polyanionic cellulose low viscosity (PAC-LV)

Polyanionic cellulose low viscosity (PAC-LV) ke mofuta oa selulose ea polyanionic eo hangata e sebelisoang e le tlatsetso marong a ho cheka bakeng sa ho hlahloba oli le khase. Mona ke kakaretso ea PAC-LV le karolo ea eona ts'ebetsong ea ho cheka:

1. Sebopeho: PAC-LV e tsoa ho selulose, polima ea tlhaho e fumanoang limela, ka phetoho ea lik'hemik'hale. Lihlopha tsa carboxymethyl li kenngoa mokokotlong oa cellulose, li e fa thepa ea anionic (e qosoang hampe).
2. Mosebetsi:
   • Viscosifier: Le ha PAC-LV e na le viscosity e tlase ha e bapisoa le limaraka tse ling tsa polyanionic cellulose, e ntse e sebetsa joalo ka viscosifier marong a chekang. E thusa ho eketsa viscosity ea mokelikeli, e thusa ho emisa le ho tsamaisa li-cuttings tse phuntsoeng.
   • Taolo ea Tahlehelo ea Mokelikeli: PAC-LV e boetse e kenya letsoho taolong ea tahlehelo ea mokelikeli ka ho etsa kuku e tšesaane ea sefelle leboteng la borehole, ho fokotsa tahlehelo ea mokelikeli oa ho cheka sebopeho.
   • Rheology Modifier: PAC-LV e susumetsa boits'oaro ba phallo le thepa ea rheological ea mokelikeli oa ho cheka, e matlafatsa ho fanyeha ha lintho tse tiileng le ho fokotsa ho lula.
3. Lisebelisoa:
   • Ho Cheka Oli le Khase: PAC-LV e sebelisoa mekelikeli ea ho cheka e thehiloeng metsing bakeng sa ho hlahloba le ho hlahisa oli le khase. E thusa ho ntlafatsa botsitso ba wellbore, ho thibela tšenyo ea sebopeho, le ho ntlafatsa bokhoni ba ho cheka.
   • Kaho: PAC-LV e ka boela ea sebelisoa e le ntho e thibelang metsi le ho boloka metsi mefuteng ea samente joalo ka li-grouts, slurries, le lirekere tse sebelisoang lits'ebetsong tsa kaho.
   • Meriana ea Meriana: Mekhahlelong ea meriana, PAC-LV e ka sebetsa e le se tlamellang, se senyang, le se laolang ho lokolloa ha letlapa le li-capsules.
4. Thepa:
   • Ho qhibiliha ha Metsi: PAC-LV e qhibiliha habonolo ka metsing, e lumellang ho kenngoa habonolo mecheng ea metsi a chekang metsi.
   • Thermal Stability: PAC-LV e boloka litšoaneleho tsa eona tsa ts'ebetso holim'a mefuta e mengata ea mocheso e kopanang le mesebetsi ea ho cheka.
   • Mamello ea Letsoai: PAC-LV e bonts'a tšebelisano e ntle le maemo a holimo a letsoai le matsoai a atisang ho kopana le libaka tsa oli.
   • Biodegradability: Joalo ka mefuta e meng ea selulose ea polyanionic, PAC-LV e nkiloe mehloling e nchafalitsoeng e thehiloeng ho limela 'me e khona ho senyeha, ho e etsa hore e boloke tikoloho.
5. Boleng le Litlhaloso:
   • Lihlahisoa tsa PAC-LV li fumaneha ka limaraka tse fapaneng le litlhaloso tse etselitsoeng litlhoko tse khethehileng tsa mokelikeli oa ho cheka.
   • Mehato ea taolo ea boleng e netefatsa botsitso le ho latela maemo a indasteri, ho kenyeletsoa lintlha tsa API (American Petroleum Institute) bakeng sa ho cheka li-additives tsa mokelikeli.

Ka kakaretso, polyanionic cellulose low viscosity (PAC-LV) ke tlatsetso ea bohlokoa ho maro a ho cheka a thehiloeng metsing, a fanang ka viscosification, taolo ea tahlehelo ea mokelikeli, le thepa ea ho fetola rheology ho ntlafatsa ts'ebetso ea ho cheka le botsitso ba hantle molemong oa ho hlahloba oli le khase.
