针对鄂尔多斯盆地西南部黄土塬地震资料严重的静校正问题,本文提出利用层析反演静校正,折射波静校正方法分别计算静校正量,按照地表一致性原则,将两种方法计算的炮点,检波点校正量各自分解为高频校正量和低频校正量,然后进行最优化组合,从而获得全新的炮点和检波点静校正量.鄂尔多斯盆地西南部黄土塬地区地震资料实际应用表明,应用本文方法计算的静校正量的地震剖面与单独应用层析静校正量或折射静校正量的地震剖面相比,其层位同相轴连续性和信噪比得到了很大的改善,从而证明本方法的正确可靠性.同时表明,本方法能够很好的解决本区静校正问题.
In order to solve the serious static correction problem of loess tableland in the southwestern Ordos Basin, this paper proposes to calculate the static correction by using the method of static inversion and static correction of refraction wave respectively. According to the principle of surface consistency, , The detection point correction amount is decomposed into high-frequency correction amount and low-frequency correction amount, and then optimize the combination to obtain a new shot point and detector static correction amount.The seismic data in the Loess Plateau in southwestern Ordos Basin show that the application Compared with the seismic sections with static correction of statics or static correction of refraction alone, the seismic sections calculated by this method have a great improvement in the continuity of stratigraphic events and the signal-to-noise ratio, which proves that The correctness and reliability of the method.At the same time, it shows that this method can solve the problem of static correction in this area well.
