摘　　要：高分辨率层序地层学认为地层基准面的周期性变化控制了层序的形成及其内部地层构成样式 ,通过露头、测井和岩心资料上不同级次的基准面旋回的划分和对比 ,可构建等时地层格架。该方法在华北地区二叠系上石盒子组地层分析中取得了良好效果 ,在非海相地层的高分辨率地层对比、分析中具广阔的应用前景。The high resolution sequence stratigraphy holds the theory that the periodic change of base level controls the form of stratigraphic sequence and the styles of the interior stratigraphic construction.By the recognization and correlation of different order base-level cycles according to outcropts,well logging and core information,the chronostratigraphic framework can be established.This theory and method is applied to the stratigraphic analysis of upper Shihezi Formation of Permian in North China and achieves good results.It has a broad application prospect in the high resolution correlation and analysis of nonmarine strata.
