摘要
针对剩余静校正问题,讨论了统计方法中的蒙特卡罗法用于反射波能量最大化剩余静校正的方法。分别论述了反射波叠加能量最大化法和蒙特卡罗方法,以及蒙特卡罗方法如何应用于剩余静校正的计算中,并用实例说明了该方法的效果。通过实际应用蒙特卡罗剩余静校正方法,解决了经野外静校正后残留的剩余静校正问题,并通过与其他剩余静校正方法的实际应用对比,说明了蒙特卡罗剩余静校正方法的优势。对于大剩余量的静校正问题,蒙特卡罗剩余静校正方法仍然可以很好的解决,并且不会产生串相位问题,说明蒙特卡罗剩余静校正方法是可靠的。
According to the residual static correction, this paper has discussed the application of statistical Monte Carlo method to re- sidual static correction which is computed by the method of maximal energy of reflected wave. The study included the detailed descrip- tion of Monte Carlo method and the method of maximal energy of reflected wave, the discussion on the way of applying Monte Carlo method in residual static correction exemplified by some practical application. As a result of processing seismic data with Monte Carlo residual static correction, the residual static state has been corrected. Based on a comparison between Monte Carlo residual static cor- rection and other residual static corrections, this paper demonstrates the predominance of Monte Carlo residual static correction. Fur- thermore, Monte Carlo residual static correction can solve obvious residual amount without phase shifting. These results show the de- pendability of Monte Carlo residual static correction.
