摘　　要：在深井煤层气藏开采过程中,力学结构强度及导流能力俱佳的陶粒支撑剂是高效开采煤层气藏的重要前提。陶粒支撑剂合成原料的二次加工有利于使其获得优质综合性能以满足在复杂的地层环境中的应用。本文对低品位铝矾土和煤矸石固废料进行陈腐处理,制备了煤层气用陶粒支撑剂,深入分析了水分浸润作用对矾土矿石原料、煤矸石添加剂等烧结性能的影响,同时探究了陈腐水化作用与支撑剂结构致密性、孔隙特征、物相尺寸等参数的变化规律。最终合成了满足煤层气开采的高品质陶粒支撑剂,为我国今后矿产资源的高效利用及煤层气藏的快速稳定开采提供了研发基础。During the course of deep coalbed gas exploitation,the ceramic proppant with a good mechanical structure and flow conductivity are benefited to improve the mining efficiency of coalbed gas.Reprocessing of proppant raw materials is conducive to obtaining superior properties to meet the application in complex stratigraphy environment.In this paper,ceramic proppant for coalbed gas exploitation was prepared by using stale treatment on the low-grade bauxite and solid waste of coal gangue.The effect between the water wettability and sintering property was analyzed with the different stale interval.The variation rules of stale hydration were investigated on proppant about the microstructure density,pore distribution and phase size.Finally,the high-quality ceramic proppant was synthesized for satisfying the demand of coalbed gas mining,which provides the research basis for the efficient utilization of mineral resources and the stable exploitation of coalbed gas in the future.
