摘　　要：鄂尔多斯盆地黄土塬区上古生界气藏是我国重要且典型的致密砂岩气藏之一,其储量大,面积广。但是由于地表采集条件较差,地震资料品质不佳,对地震地质研究造成不利影响。通过分析总结,制定了一套致密砂岩气藏地震资料处理流程,采用静校正、井控反褶积、高次项动校正等一系列特色处理技术和方法,取得了较好的效果,能够满足鄂尔多斯盆地致密砂岩储层预测的需求。The Upper Paleozoic of the loess plateau area in Ordos Basin is one of the important and typical tight sandstone gas reservoirs in China with huge reserves and excessive areas.However,due to the poor surface acquisition conditions and the poor quality of seismic data,it has a negative impact on seismic and geological researches.a set of flow on tight gas seismic data processing flow is developed,and a series of suitable special seismic processing methods and techniques,such as static correction,well controlled deconvolution and high order dynamic correction are used and good effect is obtained in application,it can meet the demands for predicting the tight sandstone gas reservoirs in Ordos Basin.
