摘要
高分辨率层序地层学研究的关键是确定等时界面。在前人提出的高频基准面转换旋回分析和关键界面（洪泛面）对比分析来确定等时性的基础上，以板中东油田板２油组水下冲积扇沉积为例，就湖盆内事件沉积的特点，提出可以结合洪泛面和事件沉积界面以及异旋回和自旋回来进行高分辨率层序地层的对比研究。实例研究结果表明，事件沉积虽然破坏了正常沉积的规律性，但它本身却是良好的等时界面。
篢he key in study of high-resolution sequence stratigraphy is to determine the isochronal surfaces. Some authors proposed that the analyses of transfer cycles of high frequency base level and key surface (flooding surface) correlation could be used to correlate isochronal strata. This paper proposes that high-resolution sequence stratigraphy correlation can be combined with flooding surfaces and event depositing surfaces, as well as with allocycles and autocycles according to lacustrine subaqueous alluvial fan event deposition. The practical application shows that this method is possible and accurate microfacies analysis. The event deposity can be taken as a good isochronal surface although it can destroy the rythem of the normal deposition.
