摘　　要：根据地层过程/响应动力学,按照旋回转换性质和沉积连续性综合分析和归纳了层序界面的类型,进而将2种性质、不同类别的界面进行了复合分类。这一分类方法是在济阳坳陷三级层序地层统层过程中认识到的,并应用到了该次统层工作中。实践证明这种分类适用于三级层序地层统层,统层结果与所选济阳坳陷各井的分层数据符合较好、分层的旋回性质全区基本一致,并得到定年资料的标定和验证。Based on stratigraphic process corresponding dynamic,according to the characteristics of cyclic reverse and sedimentary continuity,the types of sequence boundaries are systematically analyzed and summarized,the boundaries of 2 different properties of different types are integrally classified,the classification method is recognized and established during the stratum statistics of 2nd-order sequences in Jiyang Depression,and used for the stratum statistics.Application indicates that the method is suitable for the 3rd-order statistics,the result is consistent with the data obtained from stratification of each well selected in Jiyang Depression and the cyclic property is basically coincident with that of the whole region and it is indicated and proven by yearly data.
