摘要
裂缝性碳酸盐岩储层普遍具有双重介质特征,裂缝孔隙网络系统中的多相流体渗流复杂,国内外相关研究成果少。裂缝性碳酸盐岩储气库的物理模拟试验主要包括微观可视化和岩心,从宏观和微观两方面研究该类型储气库的气水两相渗流过程中的气、水两相渗流规律及注采运行机理。总结出一套现阶段针对裂缝性碳酸盐岩储气库的物理模拟评价手段,并分析了该类型储气库物理模拟研究的发展趋势,对于修正储气库库容参数,指导储气库正常高效运行具有重要意义。
Fractured carbonate reservoirs generally have dual-medium characteristics,and multiphase fluid seepage in fracture porous network system is complex.So,the research thereof is difficult and there are less related research results at home and abroad.Physical simulation of fractured carbonate gas storage mainly includes two parts：microscopic visualization and core.In this paper,gas-water percolation law and injection-production mechanism of such gas storage are discussed from both macroscopic and microscopic viewpoints.A set of evaluation methods of physical simulation applicable at this stage are proposed.Furthermore,the development tendency of the physical simulation is analyzed.The research results will have a great significance to amend parameters of gas storage capacity and guide the normal and efficient operation of gas storage.
