  • Methods for preparing liquid-solid phase change proppant with a controllable particle size based on emulsified resin
    Patent number: 11708527
    Abstract: Some embodiments of the present disclosure provide a method for preparing a self-phase change proppant based on an emulsified and toughened bio-based epoxy resin. Toughening modification is performed on the bio-based epoxy resin by graphite particles, and then the bio-based epoxy resin after the toughening modification is emulsified by SiO2 particles as an emulsifier to prepare the self-phase change proppant; a proportion of different mesh numbers in the self-phase change proppant is adjusted by changing a concentration of the emulsifier during emulsification; and the chemical formula of the bio-based epoxy resin is: The proppant particles in the present disclosure have good sphericity and high fracture permeability after being laid, which can effectively extract the remaining oil in the fractures, thus improving the development efficiency of the oilfield.
