| 摘 要： | 浊积体中河道砂体单层厚度薄,横向变化快,受断层构造影响大,利用常规瞬时振幅沿层切片方法很难识别河道砂体展布,而用地层切片构建等时地层格架,利用谱分解技术将相干属性与地层切片结合起来,运用测井相、沉积相资料可对浊积扇的河道砂体进行综合预测.将此方法运用到渤海工区中取得了较好的实际效果,查明了河道砂体的展布规律,为后期的布井钻探提供了依据.

| Abstract: | The channel sandbodies in turbidite body are characterized by little single-layer thickness,quick horizontal variation and the great influence of fault structure.Therefore it is difficult to identify the distribution of the channel sandbodies by conventional instantaneous amplitude attributes in stratum slicing.But if coherence attributes are combined with stratum slicing attributes by constructing isochronous stratigraphic framework and spectrum decomposition technology,the distribution of sandbodies in tu... |
