摘　　要：作者在文中详细探讨了C1 、C2 和C3三种相干算法及其应用。根据三维地震数据体的特点提出了实用的相干算法 ,并编制了相应的软件。我们对三种相干算法对应相干数据体的解释结果进行了细致的分析 ,C2 相干算法基本能够平衡提高横向分辨率和信噪比之间的矛盾 。Coherence cube technology has been widely used in seismic data interpretation. In the paper, its corresponding algorithms are studied in detail. We programmed useful software to get three types of coherence algorithms: C1, C2 and C3. According to analyzing, we find that C2 coherence algorithm can basically balance the contradiction between transverse resolution and ratio of signal to noise, while C3 algorithm can obtain more precise results.
