摘　　要：济阳坳陷古生界煤系地层发育,具备形成煤成气藏的条件。通过分析该区煤系地层构造-热演化史对煤成气生成、聚集的影响,指出二次生烃对煤成气的生成具有重要作用,并依据地层构造史划分煤成气成藏模式,探索成藏规律,为煤成气勘探指明方向。The coal measure strata in Palaeozoic Erathem was well developed and it possesses reservoir forming conditions for coal-derived gas pool. Through the analysis of influence of tectonic-thermal evolution history of coal measure strata in this area on generation and accumulation of coal-derived gas, this paper pointed out that secondary hydrocarbon generation is very important to reservoir formation. Reservoir formation model is divided according to tectonic evolution history. The paper discusses reservoir formation rules, providing the direction of coal-derived gas exploration.
