| 摘 要： | 叠前深度偏移速度分析需要借助于共成像点道集进行速度准确性的判断,并利用曲率更新/反演速度。本文比较介绍了几种常用的共成像点道集的提取过程、表现形式及共成像点道集的优缺点。角度域共成像点道集(ADCIGs)不会受到多路径的干扰,可以为复杂构造条件下碳酸盐岩储层速度分析与反演提供保幅成像道集。

| Abstract: | Pre-stack depth migration velocity analysis methods judge and modify the migration velocity according to the curvature that shown in CIGs. This paper gives us some introduce of some kinds CIGs, including the extraction, the expression and the relative merits. Through the comparison, it is clear that angle-domain CIGs （ADCIGs） can resolve the problem of multi-path and provide CIGs for velocity analysis and inversion of clastic rock reservoir. |
