摘　　要：鄂尔多斯盆地东缘神府木瓜区上古生界属于典型的致密砂岩气藏,储层甜点受岩性、物性多重因素控制。下石盒子组盒8段为辫状河沉积,砂岩与泥岩波阻抗差异小,因此常规波阻抗反演方法和地震属性难以达到有效储层预测。通过神经网络技术,对下石盒子组致密砂岩储层进行预测,应用效果较好,为该技术的推广应用提供了依据。The Upper Paleozoic in the Shenfu Mugua area of the eastern margin of the Ordos Basin belongs to a typical tight sandstone gas reservoir,and the sweet spots of the reservoir are controlled by multiple factors such as lithology and physical properties.The He8 section of the Lower Shihezi Formation is a braided river deposit,with small differences in wave impedance between sandstone and mudstone.Therefore,conventional wave impedance inversion methods and seismic attributes are difficult to achieve effective reservoir prediction.The neural network technology was used to predict the tight sandstone reservoir of the Lower Shihezi Formation,and the application effect was good,providing a basis for the promotion and application of this technology.
