摘要 基于页岩矿物成分的页岩脆性评价方法,由于对页岩脆性矿物的认识差异,导致脆性指数的模型也有较大差异。文章通过对龙马溪组页岩矿物分析,认为石英、碳酸盐类矿物与铁矿石类矿物为脆性矿物,长石与黏土类矿物为塑性矿物,并提出了新的页岩脆性评价模型。 The evaluation methods of shale gas brittleness based on shale mineral,will result in differences of brittleness index models owing to the different knowledge of brittle mineral.This article indicates that quartz,carbonate,and iron minerals are brittle,feldspar and clay are ductile minerals by analysis of Longmaxi shale minerals.A new model to evaluate shale brittleness is proposed as well.
