【摘要】 利用地震资料得到的表层折射初至进行静校正是目前生产中的主要静校正方法。由于此类方法较多,应用条件受到不同的限制。基于延迟时分解的静校正技术能充分利用所有地震道的折射初至,反演出近地表结构,其原理简单,不受观测系统类型限制,且计算速度较快,在近地表不太复杂的地区使用效果较好。更多还原

【Abstract】 The refraction static corrections using refraction first-break time in seismic data becomes a main method in current seismic data processing.Because of the diversity of this method and each method restricted by different conditions,it’s necessary to find a low-cost,efficacious and common method.The static correction based on the decomposition of delay time can sufficiently utilize the refraction first-break time of all the traces.This method has simple principle,faster computing speed and not be restricted by layout,so it can achieve very good results in the area where is not too complicated and near surface.更多还原
