摘　　要：在开采煤层气、页岩气等气藏资源过程中,陶粒支撑剂的产品性能尤为关键,合成密度小、强度高的支撑剂是实现气藏高产率的重要指标。本文在传统矾土系陶粒支撑剂的基础上,添加煤矸石(RCG)、羧甲基纤维素钠(CMC)和白云石(DOL)进行固相烧结,借助以上造孔剂多温区的热解作用以及高温液相快速填充机制改善支撑剂的基体孔隙分布特征,降低支撑剂的结构密度并提升基体强度。当掺入质量分数为15%RCG+1%CMC+1%DOL添加剂时,支撑剂表现出最佳的综合性能并满足气藏资源开采的参数要求。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.
