结合我国第一个盐岩储气库群--金坛储气库运行过程中观察井的压力变化监测数据,利用监测观察溶腔腔体卤水压力的变化来分析腔体体积收缩变形,并据此反演分析储气库区盐层蠕变本构方程的主要蠕变参数,使其计算结果与实际吻合,解决数值计算在地下盐岩储气库中很难被验证的问题.结合理论分析和试验的方法,验证利用观察井监测腔体蠕变收缩体积这种方法的合理性.研究成果能用于盐岩储气库运营中的长期体积变形预测、地表沉降预测等研究工作中,为盐岩储气库群的长期稳定安全运行提供技术支持.

Based on the monitoring data of the pressure change in the observation well obtained during the operation process of the Jintan gas storage group,the first salt rock gas storage group in China,the volume shrinkage deformation of the cavity is studied through the observation of the brine pressure change in the cavity of the rock-salt cavity,and thereby the major creep parameters of the creep constitutive model of the salt bed in the gas storage region is back analyzed to make the calculation results conform to the actual status,and the problem that the numerical calculation is hard to be verified in the underground gas storage is solved. By combining the theoretical analysis and test,the monitoring method of observation well,by which the volume shrinkage deformation of the cavity can be derived,is provided and verified. The research results can be applied to research such as the prediction of the long-term volume shrinkage in the operation process of salt rock gas storage and the prediction of the ground surface settlement,and also offer the technical support for the long-term stability and safe operation of the salt rock gas storage group.
