摘　　要：上第三系河道砂体油气藏是济阳拗陷重要的勘探领域之一。通过近几年对埕东凸起北坡馆陶组河道砂岩油藏的深入研究,形成了一套以地质综合分析为基础、地球物理技术为依托的比较成熟的上第三系河道砂储层描述技术及砂体含油气性判别技术。前者包括水平切片、相干分析、频谱分解等;后者包括含油性预测条件分析、地震属性差异分析、优选最佳属性、利用神经网络进行含油性预测。这套技术在实际应用中获得了满意的效果。Neogene channel sand body reservoir is one of the important exploration field in Jiyang depression. After deep study of Eg channel sandstone reservoir in northern slope of Chengdong arch in recent years, a set of more mature description technique of Neogene channel sand reservoir and oil-bearing identification technique of sand body has been formed on the basis of comprehensive geologic analysis and having the backing of geophysical technology. The former includes horizontal slices, coherent analysis and spectral factorization; the latter includes oil-bearing prediction condition analysis, seismic attributes variation analysis, optimizing optimal attributes and using neural network for oil-bearing prediction. The satisfactory results have been acquired by using this set of techniques in practical application.
