摘要(Abstract)：

为了提高煤层含气量预测效果,更准确地评价煤层气资源量、预测煤层气开发前景,以及制定合理的开发方案,基于大量文献调研,首先梳理了煤层气及煤层含气量的概念、影响因素,其次对煤层含气量预测方法的特点进行了比较分析,进而开展了煤层含气量预测方法发展趋势分析.研究表明,煤层舍气量的影响因素主要包括煤的变质程度、温度、压力、煤质、煤层有效埋藏深度、储层有效厚度、储层物性等,其中,煤变质程度起着根本性作用.煤层含气量定量预测方法主要有等温吸附曲线法、含气量梯度法、测井法、地震法等.合理选择煤层含气量预测方法,开展多学科、多种预测方法综合预测含气量研究、研发新的煤层含气量预测方法是煤层含气量预测的主要发展趋势.
