盐岩水平溶腔建腔期流体运移实验研究

采用量纲分析法建立实验相似理论并建立模拟实验平台,采用示踪剂方法观测在不同套管间距、流量条件下的流场分布情况,并用高清相机记录。以此归纳总结出盐岩水平溶腔腔内卤水运移可分为三个作用区:对流扩散区、缓冲扩散区和饱和沉淀区。计算了各区域的运移范围,并将实验得出的数据依据相似比换算成实际工程中的数值,为现场盐岩水平溶腔的高速高效建造提供指导。

Research on fluid Migration Experiment of Construction Period of Horizontal Storage in Salt Cavity

Uses dimension analysis method to establish experiment theory and prepare?the?experiment.The process of the distribution of flow field were recorded by the high-definition camera.The tracer method was apply to measure the conditions of different casing interval and fluxes.The experimental results show that the function area of migration can be divided into three zones: convection diffusion zone, buffer zone and the saturated precipitation zone.The scope of different influence zone of fluid migration are concluded. These numerical magnitudes are converted to the numerical magnitudes of the actual engineering on the basis of similitude ratio.The study of the numerical simulation has a significant and practical value for the engineering.
