摘　　要：本文提出一种叠前多偏移距抛物线信号加强的方法。在应用本方法前，只需要对地震资料进行粗略的动校正，克服叠加信号加强法需要对地震资料进行精确动校正的缺陷，避免了传统的餐后信号加强法产生的假像。对两条测线的实际地震资料进行试处理的结果表明，本方法效果较好。We present here a method called prcstack multi-offset parabolic singal cnhancement. To use the method, only rough NMO correction for seismic data is needed, which overcomes the disadvantage of precise NMO corrections rcquired for the existing prestack signal cnhancement methods and false imagcs produced by the traditional poststack signal cnhancoment methods. Experiments on two real scismic lines show that the proposed method generates good rcsults.
