【摘要】 本文通过对陆地地震数据记录实例的分析,给出了408UL在时间指数、归一化和自动增益控制三种回放方式下,如何选取合理的回放因素,从而使地震数据的回放能更加突出有效波、提高信噪比。同时,给出了回放因素取舍的理论依据。更多还原

【Abstract】 Through analyzing the case of a land seismic record, the paper gave how to select reasonable playback factors for three playback ways: time exponent, normalization and AGC, making the playback of seismic data highlight the waves of interest and improve S/N ratio; at the same time, gave theoretical basis of the choice of playback factors.更多还原
