| 摘 要： | 通延川南地区煤层气资源丰富,以其含气量高、地质构造简单、埋藏深度适中等有利条件引起了国内外煤层气地质学家的广泛关注,成为中国煤层气勘探活动最活跃的热点地区之一。该文从水文地质条件、构造条件、煤层埋深和围岩封闭条件4个方面探讨区内煤层气控气因素。结果表明水文地质条件和构造条件是延川南地区煤层气富集的主控因素,为该地区煤层气资源的进一步勘探开发提供有力支撑。

| Abstract: | The Yanchuannan Area,with high gas content,simple geological structure,modest depth of burial and other favorable conditions for coalbed methane(CBM) has great abundant CBM concentration,which caused widespread concern in CBM geologists,Yanchuannan Area is becoming China's the most active CBM exploration area.In this paper,the factors of hydrogeological,structure,Seam depth and roof seal of CBM control were discussed.The results show that the hydrogeological and structure are the main factors.This evaluatio... |
