地震资料曲流河辫状河油气储层识别与预测
A study of identification and forecasting method about the reservoir of meandering stream and braided stream

摘要: 曲流河、辫状河储层在我国的陆相盆地中广泛分布。由于曲流河相沉积砂体的单层薄、横向变化;辫状河相沉积的砂体迁移快、垂向加积等特点,增加了在勘探过程中对其分辨的难度。因此,对地震资料曲流河、辫状河油气储层的识别与预测,必须综合多种与其相关的地质资料,结合地震数据体中给出的信息来判断分析,以达到提高分辨率的目的。Abstract: The reservoir of meandering stream and braided stream are widely distributed in the continental facies basin.The sediment sand stone layers of meandering stream are thin and varied laterally.And those of braided transport quickly and aggraded vertically.They increase hardness against improving the prospecting resolution.Accordingly, for the sake of improving the resolution, the identification and forecasting about the reservoir of meandering stream; and braided stream, must be combined and analysed with several correlated geological datum and the information of the seismic sections.
