| titleOfInvention | A kind of semi-transparent membranous type profile control and water plugging oil displacement agent and preparation method thereof |
| abstract | The present invention shows a kind of semi-transparent membranous type profile control and water plugging oil displacement agent and preparation method thereof, the substance forms high-molecular compound by silica key connection polar amide group, use stability recurrent dosage form at selective oil-water type semi-permeable membrane space net structure again, with very strong heatproof, salt tolerant, resistance to salinity performance have preferable selection shut-off capacity, high permeability zone and macropore can be blocked, and generate certain section to improve ability.It can be used as the profile-controlling and plugging agent of oilfield economic adaptive type, fluid diverter. |
