盐岩储库水溶建腔机理与模拟方法研究进展

Advances in mechanism and modeling method for solution mining of salt cavern storage

针对盐岩储库地下水溶建腔过程难以观测和控制的问题,需建立水溶建腔模拟模型对腔体的发展进行设计、预测和控制,可使腔体最终形态满足长期稳定性需求。从盐岩溶解速率、卤水对流模型、不溶夹层垮塌行为、不溶杂质沉积等方面总结国内外关于水溶建腔机理与模拟方法的研究进展。结合国内外关于水溶建腔机理与模拟方法的发展现状,指出当前盐岩储库建腔建模和设计存在的问题和下一步的研究方向。

The underground solution mining of salt cavern energy storage is hard to observe or control.Therefore,a solution mining model is needed for the design,prediction and control of the cavern development,to make sure the final cavern shape meets the long-term stability requirements.The progress was concluded about the solution mining mechanism and modeling method,including the salt dissolution rate,brine convection model,collapse of the insoluble interlayers,and sedimentation of the insoluble substances.The main problems and development tendency was pointed out for the salt cavern modeling and design.
