摘　　要：The analysis of strata between wells is fundamental in the study of oil and gas reservoirs. Automatic analysis of strata between wells, based on stratigraphic division of well logs, is realized using computer techniques. We use a technique of dynamic waveform matching to build cross-well stratigraphic correlation relationships and automatically draw a path diagram of the cross-well stratigraphic contrast through piecewise line fitting, log character extraction, match cost calculation, and etc.. After analyzing many structure path diagrams between wells, 30 path patterns for normal faults, reverse faults, unconformities, synsedimentary faults, listric faults, pinch-outs, and so on were summarized and the path diagram patterns and correlation conceptions are presented. The application analysis in Dagang Oil Field shows that this method is effective.在井之间的阶层的分析在油和煤气的水库的学习是基本的。基于井木头的 stratigraphic 分割，在井之间的阶层的自动分析用计算机技术被认识到。我们使用匹配明智的线适合，日志字符抽取，匹配费用计算，和等等造跨井的 stratigraphic 关联关系并且自动地通过片拉跨井的 stratigraphic 对比的一张路径图的动态波形的一种技术……在分析在井之间的许多结构路径图以后，为正常差错的 30 个路径模式，反向的差错，不顺从， synsedimentary 差错， listric 差错，拧外面，等等被总结，路径图模式和关联概念被介绍。在这个方法是有效的 Dagang 油领域表演的申请分析。
