This paper summarizes a set of interpretation technologies for Mesozoic sandstone reservoir prediction in the Longdong loess plateau, such as seismic sequence processing and interpretation based on generalized S transform, the eroded paleo-geomorphology interpretation of the top of the Triassic and a variety of lateral reservoir predictions. The effects of employing these technologies are compared and analyzed, as well. The research results show that seismic sequence processing interpretation technology based on generalized S transform can distinguish 3ms (about the thickness of 6 m)sequence interface. Consequently the technology can ascertain the distribution of a sand body of the formation Ch 8 and expand the exploration area of the Xifeng oil field in the Longdong area.%在鄂尔多斯盆地陇东黄土塬地区地震解释中,采用广义S变换地震层序处理解释技术、三叠系顶部古地貌解释技术,以及各种储层横向预测技术,对比分析了应用效果.研究表明,用广义S变换地层层序处理解释技术可识别出约6m的层序界面,进而确认了陇东地区长8段砂体的展布方向,扩大了陇东地区西峰油田的勘探范围.
