利用现场钻取的岩心,模拟盐穴储气库水溶建腔过程,岩心尺寸小,且不能完全代表整个造腔层段的特征。经研究,提出了一种大尺寸盐岩储气库溶腔模型制备方法,采用氯化钠、泥土等材料配制盐岩溶腔模型;建立了盐穴储气库水溶建腔数学模型,利用相似比确定了实验参数;给出了利用人造盐岩模型开展造腔物理模拟的应用实例。 The core drilled on the site is used to simulate the water-soluble cavities in the salt cavern gas reservoirs. The core size is small and can not completely represent the characteristics of the whole cavities. Based on the research, a method for preparing cavity model for large-sized salt rock gas storage is proposed. Salt cavern model is formulated by using sodium chloride, clay and other materials. A mathematical model for water-soluble cavern formation in salt cavern gas storage is established. The experimental parameters were determined. The application example of the manmade salt rock model to simulate the cavitation was given.
