本文试从苏南地区地质条件出发,通过对龙潭组煤层特征（厚度、形态、结构、稳定性、分布及其煤炭资源)、煤层含气量、煤储层特征（储集空间与煤岩吸附特征)、煤变质程度、瓦斯压力、水文地质条件等方面总结龙潭组煤层气地质特征,为区内龙潭组煤层气资源现状及其勘查前景提供地质依据,并得出符合客观实际的认识。

Based on the geological characters in South Jiangsu area,the geological characters of coal-seam gases in Longtan Formation such as coal-seam characters (thickness, shape, texture, stability, distribution and coal resources), gas content, coal reservoir characters (storage space and rock absorptive characters), degree Of coal metamorphism,gas pressure,hydrogeological conditions etc. have summarized in order to provide geological bases for the present situation and exploration prospect of coal-seam gas resources in the Longtan Formation of the area and obtain knowledge according with Objective reality.
