成都盐盆富钾卤水以深层卤水形式赋存于地下4600m左右的中三叠统雷口坡组第四段（T2l4）含盐系的碳酸盐岩储层中。富钾卤水与海水蒸发系列各浓缩阶段相比,K+、B3+含量异常高,分别达53.27g/L和4994mg/L,超过海水钾盐沉积阶段,也超过综合利用和单独开采工业品位,成为当今世界上罕见的液态钾硼资源。富钾卤水尚富含Br、T、Sr2+、Li+、Rb+等多种有用成分,品质优异,构成优质化工原料水,经济价值极高。卤水具高承压、自溢特点,弹性储量大,具勘查开发前景。富钾卤水为沉积变质卤水和固态钾盐溶滤的复合成因。
Potassium-rich brine from Chengdu salt basin is deposited as a deep brine in the carbonate reservoir of the fourth member (T2l4) of the Leikoupo Formation of the Middle Triassic about 4600m underground. Potassium-rich brine is exceptionally high compared to the concentration stages of the seawater evaporation series, reaching 53.27g / L and 4994mg / L, respectively, which exceed the comprehensive utilization and exploitation of industrial grade of potassium salt in seawater, The world’s rare liquid potassium boron resources. Potassium-rich brine is still rich in Br, T, Sr2 +, Li +, Rb + and other useful ingredients, high quality, high quality chemical raw water, high economic value. Brine with a high pressure, self-overflow characteristics, large reserves of elasticity, prospecting and development prospects. Potassium-rich brine is a complex cause of sedimentation of brine and solid-state potassium salt leaching.
