三维相干数据体技术是近几年发展起来的一种三维地震解释技术。应用三维相干数据体可以确定断层的空间分布，确定目的层的岩性变化区（带）。本文介绍了用多道相关技术制作三维相干数据体的方法，并论述了三维相干数据体在实际资料解释中的应用，最后用EN地区的资料对此方法进行了实验。实验结果说明三维相干数据体不仅是有效的，而且具有速度快、无人工干预等优点。
Three-dimensional coherent data body technology is developed in recent years, a three-dimensional seismic interpretation technology. Using 3D coherent data, the spatial distribution of faults can be determined and the lithology variation zone (zone) of the target layer can be determined. This paper introduces the method of making three-dimensional coherent data using multi-channel correlation technique and discusses the application of three-dimensional coherence data in the actual data interpretation. At last, this method is tested by the data of EN region. Experimental results show that the three-dimensional coherent data is not only effective, but also has the advantages of fast speed, no human intervention.
