四川盆地海相三叠系气田水钾矿及其开发利用展望

POTASH-BEARING BRINE AND ITS EXPLOITATION IN MARINE TRIASSIC GAS FIELD WATER IN THE SICHUAN BASIN

四川盆地海相三叠系气田水钾矿分布广泛 ,品质优异。气田水钾矿除富含K+ 组分 ,构成液态钾矿资源外 ,并伴生Br-、I-、B3+ 、Li+ 等多种有用组分 ,为优质化工原料水 ,制取多种无机化工产品 ,经济价值极高。气田水钾矿有沉积变质型及固态钾矿溶滤叠加型两类 ,是四川找钾工作的新方向。

High-quality K-bearing brine in marine Triassic gas field water is widely dispersed over the Sichuan basin.Containing Br,I,B 3+ ,Li +,the K-bearing brine is of important economic value.It may be divided into 2 genetic types:sedimentary-metamorphic type and potash salt mineral leaching superimposition type which are of importance to searching for potash salt in Sichuan.
