| description | The invention provides a modified silicon carbide type ceramsite proppant and a matched fracturing fluid system and a use method thereof. The proppant is silicon carbide ceramsite with olefin groups on the surface, and is prepared by polymerizing ethylene monomers on the surface of the silicon carbide ceramsite through a plasma-initiated polymerization technology. The matched fracturing fluid is prepared by taking CO2 as a base fluid and a fluorocarbon surfactant as a tackifying and drag-reducing additive. The fracturing fluid can form strong wetting on the surface of the modified silicon carbide ceramsite, the modified silicon carbide type ceramsite proppant can overcome the problems that a conventional quartz sand/ceramsite proppant is slow in dispersion, easy to agglomerate, fast in sedimentation and the like in a non-polar CO2 fracturing fluid system, and the modified silicon carbide type ceramsite proppant and the fracturing fluid have good compatibility.
