含水层储气库气驱多相渗流机理物理模拟研究与常规油气田气驱物理模拟研究不同,前者主要是解决储气库多次注采循环条件下的气驱渗流机理模拟,因此从实验的设计和流程都有其特殊性、复杂性,但目前国内外文献对此报道甚少。通过对含水层储气库物理模拟实验流程的自主设计和研发,主要解决了3个方面的室内物理模拟评价技术,包括多次注采循环岩石应力敏感性评价技术、多次气水互驱多相渗流特征评价技术和多次注采后库容及渗流特征评价技术等,指出该评价技术系列可以为今后我国含水层地下储气库的建设与运行打下较好的理论基础。

The physical simulation study on the gas-drive multiphase flow mechanism of aquifer gas storage is different from that of routine gas-oil reservoir,it mainly solves the simulation of gas-drive flow mechanism of gas storage in the condiuion of repetitious injection-production,so from experiment design and flow,it has its particularity and complexity,and at present,it has few reports on the domestic and foreign papers.From independent design and study on the physical simulation experiment flow of aquifer gas.
