摘要/Abstract

摘要： 采用染色法在三维盐岩储气库腔体模型中进行流体运移实验研究，分析流体运移最大影响范围.研究结果表明:随腔内盐水浓度增大，流体运移最大影响范围的上下边界都向腔体顶部方向移动，促进腔体上部侧壁面盐岩溶解；随注水流量增大，径向运移速度增大，促进侧壁面盐岩溶解，并且最大影响范围下边界向腔体底部移动，促进中间管管口下部盐岩溶解.将实验数值转换为工程值，在腔内盐水质量浓度为25，50和75g/L，注水流量为60，80和100m³/h，管间距为28，42，56，70，84和98m组合条件下，得到流体运移最大影响范围数值.研究结果和方法可为工程中提高造腔效率及控制腔体形态提供参考建议和途径.

Abstract: The experiment of fluid migration is studied through staining method in the three-dimensional cavity model of salt rock gas storage， and the maximum influencing range of fluid migration is analyzed. The study results show as follows: the upper and lower boundaries of the maximum influencing range of fluid migration move towards the top of cavity with the increase of brine concentration， which facilitates the salt rock solution of the side walls of upper cavity. With the increase of water injection flow， the increase of radial migration velocity facilitates the salt rock solution of side walls， and the lower boundary of the maximum influencing range of fluid migration moves towards the bottom part of cavity， which facilitates the salt rock solution of lower part of middle tube mouth. The engineering values of the maximum influencing range of fluid migration are obtained through converting experimental values under the combined conditions of different brine concentrations (25， 50，75g/L)， water injection flows (60， 80， 100m³/h) and tubes spacing (28，42， 56， 70， 84， 98m). Research results and method can provide the reference and approach for improving cavity constructing efficiency and controlling cavity shape.

Key words: salt rock gas storage, brine concentration, fluid migration, influencing range, staining method
