【摘要】：可压裂性可用来表征页岩储层能被有效改造的难易程度,对于页岩气藏的开采具有重要影响。本文从页岩气储层岩石的矿物学、岩石力学两个方面,对赣东北底-下寒武统荷塘组页岩气储层脆性指数进行了评价。结果表明,岩石力学参数求取的页岩储层脆性指数更适用于赣东北荷塘组页岩,并根据页岩弹性模量与泊松比的分布范围,建立了适合赣东北荷塘组页岩的脆性指数预测模型。
[Abstract]:Fracturing can be used to characterize the degree of difficulty that shale reservoir can be effectively modified, which has an important influence on the exploitation of shale gas reservoir. In this paper, the mineralogy and rock mechanics of shale gas reservoir are discussed. The brittleness index of shale gas reservoir of Hetang formation of Lower Cambrian formation in northeast Jiangxi is evaluated. The results show that the brittle index of shale reservoir obtained by rock mechanics parameters is more suitable for shale of Hetang formation in northeast Jiangxi Province. According to the distribution range of modulus of elasticity and Poisson's ratio, a prediction model of brittleness index for Hetang formation shale in northeastern Jiangxi is established.
