煤层气储层性能综合评价方法与应用

Methods of integrated evaluation on coal bed methane reservoir property and its application

煤储层特征评价研究是煤层气勘探试验中和进行商业开发前所必须进行的一项技术工作。本文在煤储层性能参数单因素评价基础上,提出了进行储层特征综合评价的重要性和定量计算方法。并将此方法在安徽淮南煤田新集煤层气开发示范区研究工作中进行了应用,评价结果表明相对定性和单因素评价更为科学、合理、可信。

The evaluation and study on coal reservoir property is a basic technological work that is required to do essentially in CBM exploration test and before commercial exploitation. On the basis of single factor evaluation, the importance and quantity calculation method for the integrated evaluation on coal reservoir property is presented in this paper. The method has been applied in Xinji CBM exploitation in Huainan coal field of south China's Anhui province. The result indicates that the evaluation of relative qualitative and single factor is more scientific, reasonable and reliable.
