以往,对穿过多层含水层的钻孔,通过混合抽水(或注水)试验分别计算其水文地质参数,我们主要是通过多次抽水(有几个含水层,抽几次水)算得的。其法甚繁,效率极低,成本很高,而且如自下而上抽水时还不能保留抽水钻孔。因此,在一般的水文地质勘探中都未采用这个办法。 本文所讨论的,是利用定向流速测井仪通过孔内抽水或注水测算多层含水层水文地质参数的一种方法 In the past, hydrogeological parameters were calculated separately for mixed boreholes (or flooding) through boreholes that run through multiple aquifers, mainly by pumping multiple times (with several aquifers, pumping several times). The method is very complicated, inefficient, costly, and can not retain pumping holes, such as bottom-up pumping. Therefore, this approach is not used in general hydrogeological exploration. Discussed in this paper is a method to measure hydrogeologic parameters of multi-layer aquifers by pumping or injecting water through a hole using directional flow logging tools
