摘　　要：由于具备结构致密、孔隙度低、塑性变形能力大，非常低的渗透率、良好的蠕变行为干口损伤自愈等特性，岩盐储库被公认为石油、天然气和放射性废物的理想存储场所．基于流固耦合的岩盐储瘁损伤的过程中，内部会出现不同程度的微裂隙．随着时间的增加可能会导致微裂缝之闲的贯通，进而导致岩盐的孔隙度和渗透率在一定程度上的波动。本文通过对考盐损伤过程中渗流的研究，发现损伤和渗透率之间存在一定的关系。Because of the characters of compact structure, low porosity, large plastic delkmnation capacity, very low permeability and self-healing, salt rock cavern is internationally recognized as the ideal storage form for oil, gas and radioactive waste. During the process of salt rock reservoir damage based on the fluid-structure interaction, different degree of intemal-microcracks will appear. With the increase of time,it may cause the linking between the microcracks,and also the porosity and permeability of the rock salt in a certain degree of volatility, tn this paper, through the study of seepage in rock salt damage process.we found that there is a certain relationship between the damage and permeability.
