摘要
在测井时可多测一条井液电阻率曲线,并对曲线特征进行分析、对比,可识别含水层段横向流动及纵向补给曲线形态,以此确定含水层准确位置。利用井液电阻率曲线还可检查钻孔封孔质量、止水效果及确定钻孔水位,以解决一些钻孔及水文地质问题。
A drilling fluid resistivity curve may be logged during conventional well logging. To carry out curve signature analysis and contrast can identify horizontal flow and vertical replenishment curve configuration of aquifer sectors and used to determine aquifer position. To use drilling fluid resistivity curve can also check out borehole seal quality, water sealing up effect and borehole water table, figure out some hydrogeological problems.
