摘　　要：扶余油层组主要储集体是河道砂体,如何准确、快速地识别河道砂体是实现长垣扶余油层勘探突破的关键。本文针对萨5井区扶余油层河道砂体单层厚度小、单砂体体积小和横向变化快、常规技术难于识别的特点,在地震沉积学理论的指导下,基于高分辨保幅地震资料,采用多属性分析技术和三维可视化多体雕刻技术,实现该区河道砂体的地震预测与识别。Channel sand body is an important reservoir, how to accurately and quickly identify the channel sand body is to achieve a breakthrough exploration for placantlcline Fuyu oil layer. It is difficult to identify the channel sand of Fuyu oil layer using conventional techniques, because the feature of channel sand is a small monolayer thickness and single sand body, rapid lateral change. In this paper, using multi-attribute analysis techniques and three-dlmensional visualization of multi-body engraving technology is to realize the prediction and identification of the study area river sand, with seismic sedimentology as a guide, amplitude preservation of high-resolution seismic data as a base. And it acquires good results in practical application.
