摘　　要：盐穴储气库是保障我国天然气调峰需求的重要手段,其最重要技术之一为水溶造腔数值模拟。该技术以设计安全稳定、高效利用的腔体为目的,采用数学方法模拟腔体造腔全周期参数,目前国内已初步掌握该技术。但随着建库目标向薄盐层、低品位领域拓展,传统水溶造腔模拟软件无法实现水平井、定向对接井造腔模拟等问题愈加突出。文章通过分析水溶造腔数值模拟技术研究历史,总结数值模拟现有技术框架,预测数模技术未来发展趋势,试图呈现水溶造腔数值模拟技术框架的轮廓,为进一步深入研究层状盐岩造腔机理、编制适合我国层状盐岩工况的水溶造腔软件提供参考。Salt cavern natural gas storage is one of the best way to balance the natural gas de- mand. Leaching numerical simulation is generally considered to be the most important technology for the salt cavern construction. Aimed to build a safe and efficient cavern, leaching simulation uses mathematical methods to simulate the full cycle parameter of the cavern leaching. The technology has been mastered in domestic. However, as the target of the research and the exploration has been focus on the thin, high - insoluble salt layers, typical leaching simulation software cannot handle the complex simulation project （e. g. horizontal wells, directional connected wells ）. Based on the review of the history of leaching numerical simulation, it summarized the existing leaching simula- tion methods, which predicted the future development trend of the technology, tried to outline the framework contour of the leaching simulation, and supported the further study of the technology.
