摘要
为了准确判断某矿区岩盐层位,满足储量计算的要求,在岩盐矿勘探中采用了地球物理测井方法,实践证明,测井方法能够准确划分岩性,弥补钻探取芯不足。结合岩盐样化验结果,利用回归分析理论可求取岩盐品位与放射性强度的关系,并进行岩盐工业品位预测,结果表明利用回归分析预测岩盐工业品位是可行的,预测结果可以满足野外生产需要,为岩盐勘探提供了有用信息。
For the purpose of accurate judgment of the rock salt horizon in a certain ore district and meeting the requirement of reserve calculation, geophysical well logging method was adopted in rock salt exploration. Practice shows that the well logging method can ac- curately divide lithologic characters and make up the shortcomings of drill coring. In combination with the analytical results of rock salt samples, the regression analysis theory can be used to obtain the relationship between the rock salt grade and the radioactive intensity and predict the industrial grade of the rock salt. The results obtained by the authors demonstrate that the utilization of the regression a- nalysis to predict the industrial grade of the salt rock is feasible, and the predicted result can meet the requirement of field production and provide useful information for rock salt exploration.
