摘要

辽河外围盆地地表为丘陵和沙漠,地下断裂发育,沉积条件复杂,地震资料信噪比很低,且多次波发育等。为此,针对这些地震采集难点,通过提高激发能量、增强弱信号接收、噪声压制和多种静校正方法联合处理等比较系统的方法,信噪比和分辨率有了大幅度的提高。
Hills and deserts occupied on the surface of peripheral basins in Liaohe Oilfield, where have developed subsurface faults and complicated sedimentary conditions. Signal-to-noise ratio of seismic data is relatively low and developed multiple-time wave. Systematic method study is conducted on excitation energy enhancement,weak signal receiving and noise suppression and multiple static correction methods in terms of acquisition difficulties in the peripheral basins of Liaohe Oilfield. As a result, signal-to-noise ratio and resolution of seismic data have been increased largely.
