摘　　要：煤层气地质研究正面临以下挑战:a)煤层气成藏的地质过程与动力学机制研究,以揭示生气性和储气性的协调发展关系,查明复杂地质条件下煤层气藏的形成机理、成藏类型和分布规律;b)煤层气储集系统与聚散机制研究,以剖析煤-水-气的耦合关系与煤的储层特性共同制约煤层气的扩散、渗流、运移、逸失和聚集的过程;c)煤层气藏经济高效开发的场效应研究,以探讨地球物理场和地球化学场与人工改造、强化开采间的互动机制,有效预测煤层气的勘探开发效果。We are presently involved in the challenge of geological research on coalbed methane, including: a)to reveal the coordinated relationship between the generation and the preservation of coalbed methane and to discover the forming mechanism, pool-forming types and distribution rules of coalbed methane pools under complex geologic conditions by studying on the geologic processes and dynamical mechanism of pool-formation; b)to analyse the processes of diffusion, percolation, migration, escaping and accumulation of coalbed methane which are commonly restricted by coal-water-gas coupling connection and coal-reservoir features by studying on the reservoir systems and accumulating-disseminating mechanism of coalbed me-thane; c)to probe into the mutual stimulating mechanism between the geophysical and geochemical field and man-made reconstruction and intensified exploitation and to effectively predict the results of exploration and exploitation of coalbed methane by studying on the field effects during the economical and high-efficiency exploitation of coalbed methane pools.
