摘　　要：江汉盆地黄场盐穴地下储气库已经进入溶腔阶段,针对腔体内天然气的压力高于周围地层压力时,可能出现天然气向周围地层中的渗漏隐患,在对黄场地区潜二段盐岩的地质特征、王58储气库蠕变试验、水密性实验以及王储6井气密性试验综合分析的基础上,对运行压力、腔体直径、安全矿柱等参数进行了优化,解决了储气库运行过程中压力差过大、安全矿柱过大或者过小等问题,同时兼顾了盐穴地下储气库安全性与经济性。The underground salt cavern gas storage in Huangchang of Jianghan Basin has entered the stage of dissolution cavity.When the pressure of natural gas in the cavity is higher than that of the surrounding formation,there may be potential leakage of natural gas into the surrounding formation.Based on the comprehensive analysis of the geological characteristics of the salt rock of the second member of the potential in Huangchang area,the creep test,water tightness test of wang58 gas storage and the air tightness test of wangchu 6 well,the operation pressure,cavity diameter,safety pillar and other parameters are optimized.It solves the problems of too large pressure difference,too large or too small safety pillars during the operation of gas storage,and takes into account the safety and economy of underground gas storage in salt caverns.It provides strong technical support for the stable operation of ultra deep salt cavern gas storage,and also provides reference for the operation of similar gas storage.
