In the process of extracting coalbed methane,shale gas and other gas reservoir resources,the product performance of ceramic proppants is particularly crucial.Low synthetic density and high strength of proppant are important indicators for achieving high gas reservoir productivity.On the basis of traditional ceramic proppants,by adding raw coal gangue(RCG),sodium carboxymethyl cellulose(CMC),and dolomite(DOL)for solid state sintering,the matrix pore distribution characteristics of the proppants were improved,the structural density of the proppants was reduced,and the matrix strength was enhanced,with the help of the multi temperature pyrolysis effect of the pore forming agents and the high-temperature liquid phase rapid filling mechanism.When a mass fraction of 15％RCG+1％CMC+1％DOL additive is added,the proppant exhibits the best comprehensive performance and meets the parameter requirements for gas reservoir resource extraction.
