摘　　要：车排子地区沙湾组岩性油藏埋藏浅、厚度薄、成岩作用差,勘探效果不理想,寻求和总结适合该地区岩性油气藏的地震描述技术尤为重要。本文针对该区地质构造特征,利用层拉平切片技术确定有利储集相带,分频技术雕刻砂体,"类亮点"特征、拟声波反演两步法鉴别流体,结合振幅—厚度分析技术预测油藏厚度。实际应用效果良好。Characterized by shallow burial, thin thickness and bad digenesis of lithologic oil pool, the exploration in SHa Wan Member of CHe Paizi Area has not been satisfied conducted. So it is more important for the area to seek and summarize suitable seismic description techniques. In this paper, based on the geological structural feature of CHe Paizi Area, favorable reservoir phase belts are determined by flattening slice technique, sand body are graven by frequency division technique, fluid body are discriminated by bright spot-like feature and two step pseudo acoustic wave inversion two steps method, and the thickness of oil pool are predicted by amplitude-thickness analysis technique. A good result has been achieved in the application.
