摘要
水平井钻井+体积改造技术是非常规领域实现突破的关键。研究储层的脆弹性特征是储层是否适合体积改造的核心问题,通过岩石力学分析、全岩分析及核磁扫描等方法,建立岩心剪切破坏观察、脆性指数计算、断裂韧性计算和岩心CT与岩石力学结合的一套用于评价储层脆性特征的综合研究方法。
Study of reservoir brittle characteristics is the core problem of stimulated reservoir volume fracturing technology.Through rock mechanics analysis,rock mineral analysis and magnetic scanning method,this article establishes a core shear failure observation,brittle fracture toughness index calculation,core CT used in the evaluation of reservoir brittle characteristics comprehensive research methods.As the volume of this technology are preferably provided important basis for the parameters.The study has very important significance
