【摘要】 煤层气作为非常规气藏勘探领域,储层性质及成藏条件具有其特殊性。沁水盆地郑庄区块煤层气的生产实践进一步证明,利用地震资料是高效开发煤层气的重要保障。本文通过对郑庄区块地震资料开展精细解释,落实、分析小断层和陷落柱的分布规律,研究3#煤储层性质,利用新技术,精细预测3#煤的分布范围及高含气量的分布区,为煤层气的勘探开发提供了重要的地质依据。更多还原

【Abstract】 In the exploration domain,CBM,as a non-conventional gas deposit,has its peculiarity in reservoir character and deposit forming conditions.The CBM production practice in Zhengzhuang block of Qinshui basin has further proved that seismic data are important guarantee for effective development of coal bed methane.The paper analyzes the distribution rule of small faults and collapse columns based on the elaborate interpretation of the seismic data of Zhengzhuang block.The paper investigates the characteristics of No.3 seam reservoir,and makes an elaborate forecast of the distribution range of No.3 seam and high gas content zone using new techniques,which provides important geological basis for exploration and development of the CBM.更多还原
