摘要: 根据岩石力学稳定性,探讨了盐穴储气库溶腔的几何形状。在保证稳定性的前提条件下,对溶腔的几何形状进行了优化设计。利用压力拱模型求解了上部溶腔壁的几何参数,利用最危险滑动面模型求解了下部溶腔壁的参数,并分析了内部气压对腔壁稳定性的影响。应用实例表明,最小内压决定上部溶腔壁的设计,而最大内压决定下部溶腔壁的设计。

Abstract: The geometry of dissolution cavity of salt gas storage was investigated on the basis of the rock mechanics. The geometry of dissolution cavity was optimized for making sure stability of gas storage. The geometric parameters for the upper wall of dissolution cavity were solved by using the pressure arch model, and the geometric parameter for bottom-like bowl of dissolution cavity was solved by the most dangerous sliding surface model. The influence of internal pressure on stability of the dissolution cavity was analyzed. Application example shows that the design of top wall of dissolution cavity was decided by the minimum pressure, and the design of bottom wall of the dissolution cavity was decided by the maximum pressure.

Key words: gas storage, dissolution cavity, geometry, optimum design, pressure arch model, sliding surface model
