摘要
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,it has special accumulation conditions and controlling system because the accumulation process of coalbed methane is affected by the coalbed itself,surrounding rocks and multi-geological functions.It is greatly different from conventional gas reservoir in geologic origin,accumulation,exploring features,etc.This paper studies the seismic data,well and velocity in Zhengzhuang Region,analyzes the effect on accumulation of coalbed methane from thickness,buried depth,physical property,surrounding rock situation,structure and collapse column,etc,and forecasts logical predication to abundance zone,guides the exploration and development in the future.
