陆相页岩气勘探开发工作刚起步,常规油气储层的评价方法体系难以适用于特殊的页岩气储层。目前,国内针对陆相页岩气储层评价的工作开展得相对较少,需要建立相应的评价标准。基于国内外页岩气勘探开发,对陆相页岩气储层特征进行了分析,筛选出岩性组合、单层厚度、有机质丰度、热成熟度、脆性指数等5项评价参数。参考国内外页岩气评价方法和相关标准,针对性的提出陆相页岩气的评价标准。
The exploration and development of continental shale gas has just started, and the evaluation method of conventional oil and gas reservoirs is not suitable for special shale gas reservoirs. At present, the domestic work on the evaluation of continental shale gas reservoirs is relatively small, and the corresponding evaluation criteria need to be established. Based on the domestic and overseas exploration and development of shale gas, the characteristics of continental shale gas reservoirs were analyzed and five evaluation parameters such as lithology combination, single layer thickness, organic matter abundance, thermal maturity and brittleness index were selected. Reference shale gas evaluation methods at home and abroad and related standards, targeted evaluation of continental shale gas evaluation criteria.
