Summary
OBF-FLC22 inotora iyo molecular chimiro dhizaini dhizaini kuti ivandudze kuomarara kwecopolymer mamorekuru, uye yakaunzwa monomer kudzokorora unit ine yakakura nzvimbo vhoriyamu, iyo inogona zvinobudirira kuwedzera steric chipingamupinyi uye kugadzirisa mhedzisiro yekudzikisa HTHP yekusefa kurasikirwa kwechigadzirwa.Panguva imwecheteyo, kuburikidza nekusarudzwa kwekushisa uye munyu kusagadzikana monomer, kukwanisa kwekushisa uye munyu inodzivirira calcium yakawedzerwa.Chigadzirwa chacho chinokunda zvikanganiso zveyakajairwa polymer fluid kurasikirwa inoderedza, senge kushomeka kweshear kuramba, kusaita munyu calcium kuramba uye isingagutse HTHP yekurasikirwa kwemvura yekudzikisa maitiro.Iyo itsva polymer fluid kurasikirwa inoderedza.

Features
OBF-FLC22 ine yakasimba munyu kuramba.Kuburikidza nezviyedzo zvemurabhoritari, munyu wemumvura yekuchera inoshandiswa pakuongorora yakagadziriswa, uye kuramba kwemunyu kweOBF-FLC22 chigadzirwa kwakaongororwa mushure mekuchembera pa200 ℃ mu base slurry ine munyu wakasiyana.
OBF-FLC22 ine yakanakisa kupisa kugadzikana.Muchiyedzo chemurabhoritari, tembiricha yekuchembera yeOBF-FLC22 yakawedzera zvishoma nezvishoma kuti iongorore tembiricha yekudzivirira yezvigadzirwa zveOBF-FLC22 mu30% munyu slurry.
OBF-FLC22 ine kuenderana kwakanaka.Kuita kweOBF-FLC22 yezera pa200 ℃ mumvura yegungwa, composite saline uye saturated saline drilling fluid masisitimu akaongororwa nekuedza kwemurabhoritari.
