摘要
为有效解决煤层气开发过程中产能精准预测的技术问题,提高气藏资源评价结果的可靠性,对含瓦斯煤渗透特性参数—孔隙率测试方法的研究背景及研究价值进行了介绍。阐述了不同应力环境、不同气体压力等条件下的含瓦斯煤渗透特性参数—孔隙率的测试方法,分析了不同研究方法的特点、适用范围及其最新进展,并对煤体孔隙结构演化与瓦斯流动的映射规律研究成果进行总结。分析认为:含瓦斯煤渗透特性参数—孔隙率同步测试方法的研究涉及多学科交叉,需加强多物理场耦合作用影响下含瓦斯煤渗透特性参数—孔隙结构演化的表征方式、与当前常规煤层增透工艺相匹配的测试方法及测试精度提升等方面的研究。
In order to effectively solve the technical problem of accurate production capacity prediction in the process of CBM development and improve the reliability of gas reservoir resource evaluation results,the research background and value of permeability parameter-porosity test method for gassy coal were introduced. The testing method of permeability parameter-porosity test method for gassy coal under different stress environment and different gas pressure was expounded. The characteristics,application range and the latest progress of different research methods were analyzed,and the research results of pore structure evolution and gas flow mapping rule of coal body were summarized. It is concluded that the research on simultaneous testing method of permeability parameters-porosity for gassy coal involves interdisciplinary research,it is necessary to strengthen the research on characterization of permeability parameters of gassy coal under the influence of multi-physical field coupling,the testing method matching with current conventional coal seam permeability enhancement technology and the improvement of testing accuracy.
