淡水资源勘探无岩心钻进的电测井方法

Electro-well logging method on coreless drilling for freshwater resources

根据电测井所得数值,通过造浆水影响改正及颗粒度影响改正后,利用相关图判定地层水矿化度,达到半定量或接近定量分析水平,完成淡水勘探中只对淡水层进行评价,进而实现无岩心钻进,结合抽水试验结果,优化取水位置,获取水质好、涌水量大的效果。

According to the data obtained from electro-well logging, and through mud-making water and particle size correction influence, and the use of correlation chart to determine the degree of mineralization of formation water, and reach the level of semi-quantitative and near quantitative analyses, fulfill the freshwater layer evaluation in freshwater exploration and then realize coreless drilling.
