【摘要】 本文通过对南黄海海域主要地层界面反射波旅行时的理论模拟计算,分析了不同时距方程在长排列条件下的旅行时误差特征,对各方程的适用性作出了评价。鉴于时移双曲线方程在南黄海地震资料最大炮检距范围内具有计算旅行时误差较小且稳定、形式简单且参数易求取等特点,故选此方程对该盆地勿南沙隆起区长排列地震资料进行了动校正和叠加测试,结果表明时移双曲线公式有利于更好地校平反射同相轴、保留更多的大炮检距道信息,从而提高南黄海海相地层的地震反射成像质量。更多还原

【Abstract】 In the paper,we calculate the traveling time of main formation interfaces in the South Yellow Sea,and analyze traveling time error characteristics with different time-distance equations under the long spread.After that,we evaluate the applicability of these equations.Since the time shifted hyperbolic equation is stable and simple with less traveling time error and clear parameters under the maximum offset in the area,we process long spread seismic data in the Wunansha uplift area with the equation.Results show that the time shifted hyperbolic equation can correct reflection events and remain more information of far offsets,and the seismic reflection imaging of marine sediments in the South Yellow Sea Basin is enhanced.更多还原
