| 摘 要： | 裂缝分布模式的差别导致了介质速度属性的不同，带来了共中心点道集的动校正剩余时差，进而影响了共中心点道集的叠加效果，增加了资料处理和解释的复杂性。而这些复杂性包含了裂发布特征的信息，通过不 同的处理方式提取和解释这些复杂性包含的信息，使得利用纵波地震资料寻找有利裂缝发育带成为可能。

| Abstract: | Difference of fracture-distributed pattern leads to variation in velocity distribution of medium,which brings about residual NMO on CMP gather,so that changes stack section of CMP gathers and increases complexity of data procession and interpretation.These complexities also include distribution character of fracture.It is possible to look for the favorable fracture development by using seismic P-wave data and through different processing to extract and interpret these complexities. |
