| 摘 要： | 延川南地区是鄂尔多斯盆地石炭—二叠系含煤系的主要分布区。通过研究延川南地区的主力煤层厚度、埋深、煤岩煤质特征及演化程度、煤层吸附性、煤储层物性及含气性、煤层气保存条件等因素,认为延川南地区煤层具有层数多、主力煤层厚度大、储层含气量高、顶底板封盖性能好、构造简单等特点,具有很好的煤层气富集成藏条件,是中高煤阶煤层气勘探有利目标区。与已获得较好煤层气勘探开发先导试验效果的大宁—吉县和韩城地区相比,延川南地区具有较高的煤层气勘探开发潜力。

| Abstract: | Yanchuannan is a main area for the Carboniferous-Permian coalbed distribution in the Ordos basin.Based on a systematic research on the main coalbed thickness,depth,coal quality,evolution degree,coalbed absorbability,reservoir physical property,gas bearing,and coalbed methane preservation,Yanchuannan has favorable coal beds and depth,high gas bearing and stable tectonic,which contributes to the coalbed methane accumulation and makes Yanchuannan as a favorable target of medium and high coal rank coalbed metha... |
