伴随煤层气开发规模的不断扩大,煤层气井的数据类型及数量越来越丰富,从而可以为研究不同构造模式下煤层气井的产能提供足够的数据支撑。从研究区的构造特征入手,与实际生产数据相结合,对构造特征对煤层气富集的关系进行分析,最终分析认为:成煤期后的地壳的抬升运动会打破煤层中原有的吸附平衡条件,在保存条件不利的情况下,易使煤层气运移逸散;构造运动形成的断裂对煤层气的保存和逸散起着重要的影响作用;由于构造运动形成的规模不等的褶皱,在不同程度上影响煤层气的富集成藏作用。
With the continuous expansion of coalbed methane development, the types and quantities of CBM wells are becoming more and more abundant, which can provide sufficient data support for studying the productivity of CBM wells under different tectonic models. Starting from the tectonic characteristics of the study area and combining with the actual production data, the relationship between tectonic features and coalbed methane enrichment is analyzed. The final analysis shows that the uplift movement of the crust after coal formation will break the original adsorption equilibrium conditions in the coal seam, In the unfavorable conditions, it is easy to transport and escape the coalbed methane. The faults formed by the tectonic movement play an important role in the preservation and escape of coalbed methane. Due to the varying sizes of folds formed by tectonic movement, The degree of impact on the enrichment and accumulation of coalbed methane.
