| 摘 要： | 影响煤层气可采性的主要地质因素有：煤层的渗透性、储层压力、含气饱和度、解吸率等。其中煤层的渗透性是关键因素之一，包括煤体结构和割理发育程度两个方面。依据各项地质条件分析，对豫西各煤田进行评价选区，认为平顶山等煤田的煤体结构保存较好，割理发育，煤层气可采性较好，为下步煤层气试验开发的有利地区。

| Abstract: | Main geologic factors that influence recoverability of coal-seam gas include coal-bed permeability, reservoir pressure, gas saturation and desorption rate. Permeability of coal bed is one of the critical factors involving coal bed structure and development of cleating. The coalfields in the west of Henan province are evaluated and sorted based on analysis of all the geologic factors. The Pingdingshan coalfield, with well preserved coal bed structure and well developed cleating, is believed to have high recoverability of coal-seam gas and is a favorable area for future pilot development. |
