摘要
给出了地震勘探分辨率的１０种定义，由此得出提高地震勘探分辨率的６个结论及提高垂向分辨率的５项措施。此外，对药量、采样率与分辨率的关系作了深入的讨论，认为：①多井小药量组合爆炸信号既有小药量的频谱特征，又有大药量的振幅特征，能解决单井药量使有效波高频能量减弱、高频段信噪比降低等问题；②采样率要适当，不但要提高时间采样率，而且还要提高空间采样率，以避免时间和空间假频对ｆ－ｋ滤波及偏移等多道处理带来的致命影响．
definitions of seismic resolution are presented and 6 conclusions are drawn to raise the resolution. According to these definitions, 5 measurements can be made to improve the vertical resolution of seismic exploration. Relationships between the resolution, excitation and reception conditions are discussed in detail.
