摘　　要：二维相干分析技术是基于地下地质条件的变化,引起的地震信息差异。它通过相邻地震道地震信息的相似性比较,用数学方法加以实现,来达到地质现象的可视性。二维相干分析的基本原理说明了二维相干分析的应用方法,尝试了二维相干分析应用于川南鱼塘潜高、白节滩构造茅口组裂缝性储层的识别和描述,介绍了其实现过程及取得的效果,指出二维相干分析是裂缝性油气藏描述的一项非常有效的技术。2D coherent analysis technique is based on the seismic information variation caused by subsurface geologic conditions and it is carried out through similarity comparison of information features in adjacent. The paper presents the application of the method to a real case of the fractured reservoir detection and characterization in Maokou Formation in Baijietan and Yutang structures in the south Sichuan and introduces its procedure and efficiency. The results illustrate that 2D coherent analysis is a very effective technique for the fractured reservoirs characterization.
