  • Modified graphite particle system for strengthening polymer/binary/ternary composite oil displacement system and preparation and application thereof
    Patent number: 10294409
    Abstract: The invention provides a modified graphite particle system for strengthening a polymer/binary/ternary composite oil displacement system. The modified graphite particle system comprises the following components: 1-5 parts by mass fraction dispersed graphite particles, 0.2-0.6 parts by mass fraction dispersant, 0.1-0.5 parts by mass fraction wettability modifier, and deionized water that accounts for the remaining content, based on 100 parts by total mass fraction of the components. In addition, the present invention also provides a preparation and a use of the modified graphite particle system for strengthening the polymer/binary/ternary composite oil displacement system.
