摘　　要：目的利用测井曲线资料识别水下分流河道砂体中的夹层。方法以靖安油田盘古梁长6油层为例,通过观察分析岩心及对水下分流河道储层砂体夹层在自然电位、自然伽马、声波时差、微电极等电测曲线的精确读值,进行岩性特征和电性数值拟合。结果建立了盘古梁长6油层砂体中泥质、钙质夹层的测井曲线定量识别模型。结论经实际应用,该夹层识别模型对划分盘古梁长6油层砂体中夹层时可操作性较强,应用效果良好。Aim To analyze the interlayer of the underwater distributary channel using the well log curve. Methods Taking the Chang 6 reservoir in Pan＇guliang, Jing＇an Oilfield as an example, to fit the lithologic characteristic and the electronic data according to the analysis of the cores and evaluate the data in the well log curve of the interlayer of the underwater distributary channel. Results The well log curve identifies modeling system of muddy and calcicolous intercalation of Chang 6 reservoir in Pan＇guliang, Jing＇an Oilfield has been established. Conclusion The application of the well log curve identifies modeling system works well in practice.
