煤层气作为一种非常规气藏,其成藏过程受煤层本身、上下围岩及多种地质作用的影响,具有其特殊的成藏条件和控制系统。与常规气藏相比,无论在地质成因、储集、开采特征等均有很大不同之处。对郑庄区块地震、井、速度等资料展开研究,从煤层厚度、埋深、储层物性、围岩条件、构造、陷落柱等多方面分析其对煤层气成藏影响,并对煤层气富集成藏区进行合理的预测,为下一步勘探开发提供指导。
As an unconventional gas reservoir, CBM is affected by the coal seam itself, the upper and lower surrounding rocks and various geological functions. It has its own special reservoir forming conditions and control system. Compared with the conventional gas reservoirs, there are great differences in geological formation, reservoir and mining features. This paper studies the seismic data of Zhengzhuang block, well and velocity, and analyzes its influence on CBM formation from coal seam thickness, burial depth, reservoir physical property, surrounding rock conditions, structure and collapse column, Enrich the integrated reservoir area for a reasonable forecast, provide guidance for the next exploration and development.
