摘　　要：为了明确建库过程中气、油、水三相的渗流机理,应用三类典型储层的平面可视化仿真模型开展了油藏水驱开发和高含水油藏建储气库的物理模拟实验,根据模型的可视化特征和实验数据分析,明确了不同高含水油藏建库过程中气、油、水三相的渗流机理与规律,评价了高含水油藏建库的库容量。结果表明,水驱油的渗流通道是油藏建库的主要空间,高含水油藏的残余油饱和度在建库过程中基本不发生变化,最终的含水饱和度取决于油藏的类型与储层的非均质程度。There are oil,gas and water in high water-cut reservoirs used for the construction of gas storage,which will bring a lot of uncertainties to the construction of gas storage. So it is necessary to understand the percolation mechanism of gas,oil and water in the gas storage. Visual simulation models of three typical reservoirs are used for studying the processes of water flooding and building gas storage. According to the visualization features the models and the analysis of experimental data,the percolation mechanisms and laws of oil,gas and water in the three typical reservoirs are obtained,and their storage capacity are evaluated. The results show that the seepage channels in water flooding are the main space for gas storage. The residual oil saturation of the high water-cut reservoirs does not change in building gas storage. The type and the heterogeneity degree of the reservoirs decide their final water saturation. The research results are of important guiding significance to the selection of the high water-cut sandstone reservoirs for gas storage and the construction of gas storage.
