Title:
AMPHIPHOBIC FLUORINE-CONTAINING NANOFLUID, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/083144
Kind Code:
A1
Abstract:
The present invention relates to an amphiphobic fluorine-containing nanofluid, a preparation method therefor and an application thereof. The amphiphobic fluorine-containing nanofluid is composed of a nanocore material and a polymer shell material. The surface of the nanocore material is grafted with a coupling agent with double bonds, and the polymer shell material contains a fluorine polymer. The present invention further provides a preparation method and application for the amphiphobic fluorine-containing nanofluid. The amphiphobic fluorine-containing nanofluid of the present invention has extremely strong wetting reversal capability, can be used for reservoir reformation of an oil reservoir, can convert reservoir wettability from hydrophilic and oleophylic to remarkable amphiphobic property, and effectively solves the liquid lock effect and the Jamin effect caused by the reservoir wettability.
