关于提高地震勘探分辨率的问题
On the Raising of Resolution of Seismic Exploration
【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.
【Abstract】 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.
