中文摘要： 以我国层状盐岩能源地下储库工程为背景，开发适合于模拟盐穴储库地质环境的损伤层状盐岩自愈合试验平台。利用超声波技术及细观力学试验方法，研究层状盐岩受损界面在不同地质环境下的自愈合特征及损伤自愈合区渗透率变化规律。旨在探索含夹层盐穴储库环境因素对层状盐岩损伤界面自愈的影响程度，揭示层状盐岩损伤界面自愈合规律，明确损伤界面自愈合度与渗透率之间的关系，建立层状盐岩界面损伤-愈合-渗透率之间的关系模型，为规避层状盐岩油气储库渗漏诱发的灾变提供理论指导和技术支持。

英文摘要： Taking the bedded salt rock energy underground storage project in China as background, development suitable for the simulation salt cavern reservoir geological environment damage bedded salt rock self-healing test platform. The self-healing characteristic and permeability variation of damaged layered rock salt interface in different geological environment are studied, using ultrasonic wave technology and micromechanics test methods. Explore the self-healing of damaged bedded rock salt interface impacted by geological factors of rock salt storage. Reveals the self-healing laws of the damaged bedded salt rock. Definitude the relation between the self-healing and permeability. Build the mathematicl model of damage, self-healing and permeability. Provide theoretical guidance and technical support to circumvent bedded rock salt oil and gas reservoir leakage induced catastrophic.
