摘　　要：以松树头煤矿水文地质勘查为例,介绍了测井曲线在含水层解释中的应用。实例表明,自然伽马、自然电位和视电阻率三种曲线对含水层具有明显的异常反应,在含水层中,前二种曲线表现为负异常,后者表现为正异常;对于隔水层,前二种曲线则表现为正异常,而视电阻率表现为负异常。根据测井解释成果与钻孔消耗量、岩心及抽水试验资料相互印证,解释松树头煤矿ZK5-2钻孔368.30～406.42m段,从上到下依次为含水层、隔水层、含水层、隔水层四段。另外,从实例应用的三种曲线可知,视电阻率曲线对于岩石粒度及含水层具有明显的响应特征,极差高达117Ω.m。Taking the hydrogeological exploration in the Songshutou coalmine as an example,introduced the application of well logging traces in aquifer interpretation.The example has shown that the gamma-ray,spontaneous potential and apparent resistivity 3 kinds of traces have obvious anomaly on aquifers;the former two shown negative anomalies,while the later positive anomalies.On aquifuges,the former two appear as positive anomalies,later negative anomalies.According to mutual confirmation between well logging results and drilling fluid consumption,rock core and pumping test data,has interpreted the 368.30~406.42m sector in borehole ZK5-2 in Songshugou coalmine shown as 4-layer configuration of alternative 2 aquifers and 2 aquifuges from top to bottom in turn.Besides,from 3 kinds of traces applied in the example can see,the apparent resistivity traces have obvious responding characters on rock granularity and aquifer,their vertex differences can be 117Ω·m as high.
