摘要
流量测井法是目前确定含水层位置、厚度、层数及分层流量和渗透性能最有效的方法.以银川市红墩子矿区红四井田S1801号钻孔为例,利用简易流量测井法确定了该钻孔的两个含水层深度和厚度,并采用承压稳定流计算公式求取了水文地质参数,该成果与抽水实验结果较为吻合,为矿区建井设计提供了依据.
In the hydrogeological exploration,when encountered thick or multi-layer aquifer,the only method is pumping with artificially layered,but it can only get the average of the whole aquifer in the test section,not the capacity of thick single-layer or a certain part of the aquifer.Simple flow logging method is such a method which get the well fluid flow state on the bases of analysis the changes in fluid flow at different depths,it will definite depth and thickness of the two aquifer of S1801 drilling in Red Four minefield,and get the hydrogeological parameters with steady flow pressure formula,the results are more consistent with the pumping test results,that will provide the basis for well design and construction
