摘要:

为了研究盐穴储气库溶腔过程中不同排量对排卤浓度及腔体形态的影响规律,通过对溶蚀速率公式的推导及变形,分析了排量与排卤浓度及造腔体体积的相关性,而后利用WinUbro 造腔数值模拟软件建立了理想的腔体模型并赋予其一定的假设条件进行对比分析。为了验证所得结论的可靠性,对金坛现场溶腔井进行数据统计与整理,对各个溶腔阶段进行对比与分析,并以部分井的典型阶段为例进行详细分析,所得结论与理论分析一致,即溶腔时注淡水排量越小,排卤浓度越高,腔体形态越规则。

Abstract:

In order to identify the effect of different displacements on the brine displacing concentration and cavity form in the process of dissolving cavity, the dissolution velocity formula is deduced and transformed to analyze the correlation between the displacement and brine displacing concentration and the cavity volume. Then, using WinUbro cavern numerical simulation software, an ideal cavity model is established and used for comparative analysis under certain assumptions. To verify the reliability of the conclusions, the data of cavity wells in Jintan are collected, and compared and analyzed for each stage of dissolving cavity; detailed analysis is made for typical phase of some wells, deriving the conclusion which is consistent with results of theoretical analysis, namely, the smaller the freshwater displacement is, when dissolving the cavity, the higher the brine displacing concentration and the more regular the cavity form are.
