摘　　要：将相干分析技术引入到层位标定中,依据构造、沉积背景、储层演化的不同及其地震响应特征的多样性,提出了相关函数最优分析、大时窗抗干扰相关函数最优分析与分段小时窗相关函数最优分析精细地震地质层位标定技术.通过合成地震记录与井旁道地震波形特征的相关分析,实现层位标定的高精度自动优化对比,方法具有精度高、速度快、客观性强的特点,实例证实是可行性的,并获得明显的地质钻探效果.Correlative analysis is successfully applied to seismic specification. According to difference of structural & depositional background, reservoir evolution and diversity of seismic responsive characteristic, The paper suggests more methods of fine seismic geology specification-correlative function optimal analysis of Random, Long-window & resistant disturbance and Short-window & subsection. Be means of correlative analysis of synthetic seismogram and seismic wave characteristic nearby boreholes, it carrys out high precision auto-optimization correlation of seismic specification. These are high precision, high efficiency and good object characteristic. Therefore, more examples are practicable and apparent effects are gained in geology and drilling.
