别勒滩低品位钾盐固液转化试验水动力与水化学条件分析

Hydrodynamic and hydrochemical condition analysis of low grade solid potassium liquefy exploitation experiment

文章从溶剂、原地晶间卤水、溶出液三个方面,通过察尔汗盐湖别勒滩区段低品位固体钾矿驱动溶解开采试验所取得的监测数据,定性的分析了水位和水质在在纵向和横向上的变化,并且分析了晶间卤水各离子浓度随深度的变化,最后分析了S2T1孔晶间卤水各离子浓度随时间的变化,并根据固液转化的特征划分了不同的阶段,即:对于供卤渠与S2T1孔之间的盐层,第1～11天,处于溶解驱动前阶段,第12～100天,处于光卤石阶段。

The article pointed out the change of underground brine level and components in cross section orientation and transection orientation by analyzing the data from driving and dissolving experiment in Qarhan Salt Lake,and the article also pointed out the concentration change with depth.The article analysed ion concentration changes over time of S2T1 well and divided the experiment into different stages according to the features of the solid-liquid transformation.
