沁水盆地南部煤层气田煤层气成藏条件分析

Analysis of the generation conditions of coalbed gas reservoir, southern Qingshui Basin

摘要: 煤层气藏具有其自身的形成条件和气藏特征。本文从煤层气藏的形成和保存条件出发,以沁水盆地南部煤层气田为实例,从沉积、构造、煤岩演化程度、顶底板条件、水动力、地应力等方面论述了煤层气成藏特征及高产富集因素,对下一步勘探具有重要指导意义。

Abstract: The generation conditions and characteristics of coalbed gas reservoir are different from others. Based on conditions of the generation and conservation of coalbed gas reservoir the paper discussed about the generation characters from deposition, structure, revolution,seal beds, hydraulic and stress conditions, which may give direction to coalbed gas exploration.
