摘　　要：江汉盆地黄场盐岩储气库处于一期一阶段溶腔阶段,当腔体内压高于围岩压力时可能出现天然气向周围地层的渗漏隐患,因此开展盐岩储气库稳定性评价十分必要。在对黄场地区潜二段盐岩层及夹层的性质、渗透率,盖层单轴压缩试验、水密性试验、气密性试验、围岩变形量、塑性区综合分析的基础上,对运行压力、腔体直径、安全矿柱等参数进行了优化,解决了储气库运行压力过高或者过低,腔体直径与安全矿柱过大或者过小等问题,为盐岩储气库效益、稳定运行提供指导。The Huangchang Salt Rock Gas Storage in Jianghan Basin is in the stage of one-stage dissolution cavity.When the pressure in the cavity is higher than the surrounding rock pressure,the hidden danger of gas leakage to the surrounding strata may occur.Therefore,it is necessary to carry out the stability evaluation of salt rock gas storage.Based on the comprehensive analysis of the properties and permeability of salt rock and interlayer,uniaxial compression test,water tightness test,air tightness test,deformation of surrounding rock and plastic zone,the operating pressure,cavity diameter,safety pillar and other parameters are optimized to solve the problem that the operating pressure of gas storage is too high or too low,the cavity diameter and safety pillar are too large or too low.It can provide guidance for the benefit and stable operation of salt rock gas storage.
