摘要
介绍了泥页岩(粘土矿物)水化的研究现状,包括泥页岩的水化过程、强弱结合水的区分,泥页岩中文换性阳离子种类及含量、介质中电解质种类及浓度对泥页岩水化的影响,温度、压力对粘土膨胀的影响,泥页岩强度与其含水量的关系。建议以后应重点研究泥页岩申各种组分和微观结构、温度、压力及钻井液添加剂对泥页岩水化的影响及泥页岩水化对其力学特性的影响,注重泥页岩水化同力学的耦合研究及泥页岩分类的研究。
The hydration stages, distinction of combined water, variety and content of exchange cation in shale, influence factors of shale hydration, influence of temperature and pressure on clay swelling, the relation between shale strength and its moisture are introduced in detail. Research direction on shale hydration is also presented.
