摘　　要：页岩储层脆性特征是可压性评价中的重要环节,对于评估页岩油气的开采潜力和制定合理的开发方案具有重要意义。通过综合介绍页岩储层脆性评价的常用方法和技术,结合产气剖面、测试产能等资料进行统计分析认为,脆性与产气性具有很好的正相关性,为水平井的靶窗优选、分级分簇优化等提供科学依据。The brittleness characteristics of shale reservoirs are a crucial aspect of formation fracturing property evaluation,which is significant for evaluating the producing potential of shale oil and gas and formulating reasonable development plans.By providing a comprehensive introduction to common methods and technologies for evaluating shale reservoir brittleness and analyzing gas production profiles and test capacities,it is concluded that brittleness has a strong positive correlation with gas production.This provides scientific evidence for optimizing target windows and the staged clustering of horizontal wells.
