摘　　要：地震相干体技术可在相干切片上直观的反映构造和断层的分布特征。C3相干算法较前两代具有更高的横向分辨率和更佳的稳定性,为了提高运算效率,将Rayleigh商加速法引入C3相干算法中,并对实际三维地震数据进行了处理。结果分析表明,采用Rayleigh商加速法可减少迭代次数,缩短计算时间,效果较为明显。The technique of seismic coherence cube can be used to directly reflect the distributional characteristics of structures and fault zones on coherence slice. C3 coherent algorithm had higher lateral resolution and better stability than those 2 formar algorithms. For the purpose of raising operation efficiency, Rayleigh quotient acceleration algorithm was introduced into C3 algorithm by 3D seismic data. The analysis result indicates that Rayleigh quotient acceleration algorithm can be used to reduce the iterated times, shorten the calculation time , therefore obvious effect is achieved.
