四川盆地地下盐卤水的水文地球化学特征

本文讨论了地下盐卤水的分带性、同位素组成和浓度场的形成以及溴、碘、硼、锂、钾在地下盐卤水中的分布。从而认识到四川盆地从震旦系至白垩系不同类型的储集岩中赋存多层盐卤水,在成因上以沉积变质型盐卤水为主,溶滤型盐卤水次之。同时,还指出盐卤水矿化度与储集岩岩相、地球化学条件、构造及古水文地质条件密切相关。

THE HYDROLOGIC GEOTHEMISTRY CHARACTERISTICS OF UNDERGROUND SALT BRINE WATER IN SHICHUAN BASIN

Discussions on the formation of underground salt brine water concentration field, zoning and isotope constitution, the distributions of Br,I,Be,Li, K in salt brine water with in this paper, we come to the cognition that the salttbrine water in shichuan basin which, from sinian systems to the cretaceous systems,exists in different types of reservoir rock,the sendimental metamorphic salt brine water is primary and the iixiviation salt brine water is minor in its origin. This paper also points out the interrelations between the mineralization of salt brine water and the lithofacies of reseroir rock-geochemistry condition and construction-ancient hydrdogic geologic condition.
