盐穴储气库水溶建腔相似模拟理论研究

摘要

In order to simulate flow field distribution in the cavity body during the process of natural gas storage building in salt caverns ,so as to improve the construction efficiency of gas storage ,the equation analysis of model method was used to derive the similar criterion upon which the similarity model was established ,the obtained modified Euler criterion was based to build the similarity model in terms of the specific size of cavity diameter ,inner tube ,and outer tube under scalar ratio 1∶70 ,and the similarity experiment platform was accordiagly established .%为研究天然气岩盐储气库建造过程中腔体内流场分布，以提高储气库建造效率，运用模化方法中的方程分析法推导出相似模型建立所依据的相似准则，并根据得出的修正欧拉准则，确定了相似模型的腔体直径、内管、外管在相似比1∶70条件下的具体尺寸，以此来建立相似模拟实验平台。本研究结论可为天燃气岩盐储气库建造提供理论依据。
