夹层的渗透率是深部层状盐岩中能源储库密闭性评价的关键参数。针对我国深部层状盐岩中常见的3种典型夹层,采用稳态气测法测试了渗透率并给出密闭性分析结果。研究指出:(1)3类典型夹层的低渗特征明显,渗透率均为10~(-2)~10~(-5) mD;但各盐矿区的夹层岩性及地质条件差别较大,导致渗透率出现较明显差异,其中以平顶山硬石膏泥岩的渗透率最低、渗透率变化范围居中;金坛灰质泥岩渗透率次之、变化范围却最大;而淮安含盐泥岩渗透率最高、变化范围最小。(2)静水压力对渗透率的影响极为显著,具体表现为静水压力越大渗透率越低;存在某一“压密临界压力”,当静水压力位于该值前渗透率随静水压力增大而急剧下...

The permeability of interlayer is a key parameter for the tightness evaluation of energy storage caverns constructed in bedded rock salt formations. Thus, the steady gas flow method of permeability tests for typical interlayers of 3 kinds of bedded rock salt areas of China, as well as the analysis of tightness evaluation, has been carried out. The research indicated that: (1) The low permeable properties of the three kinds of typical interlayers are very obvious, with the corresponding permeability range of 10-2-10-5mD. Due to the large difference of petrophysical properties and geological con...
