老挝万象平原钾盐矿床沉积特征地震解释

老挝万象平原钾盐矿具有典型的底辟构造特征,次级盐隆起和盐凹陷规模较小,但十分发育,仅依靠钻探工作,难以控制次级盐构造的范围,而地震勘探能对不同的底辟构造样式都有明显的反映,对于探明次级盐构造,以及盐构造与钾盐矿的厚度变化关系,寻找有利钾盐矿开采靶区具有重要意义。

Seismic Interpretation of Potash Deposit Sedimentary Characteristics in Vientiane Plain, Laos

The potash deposit in the Vientiane Plain, Laos has typical diapir structural characteristics. Its secondary doming and salt depression have rather small scales, but very well developed. Depending only drilling works is hard to control the secondary salt structure hounds, while the seismic prospecting can reflect different diapiric structures clearly. Thus the method has great significance on secondary salt structure proving, identifying relationship between salt structure and potash salt thickness variation, and finding favorable potash salt mining target.
