本文介绍了以基准面升降为驱动机制的高分辨率层序地层学的理论和方法。此方法是在沉积相分析的基础上，通过沉积体积划分和相分异反演出可容纳空间的单向迁移方向、地层叠置样式、基准面升降及界面位置，进而划分出不同级次的基准面旋回（即层序），并由长期旋回到短期旋回逐级进行对比。此后，作者用该法对以陆相沉积为主的山西大同晚古生代煤系进行详细划分对比，澄清了过去某些模糊认识，探讨了聚煤作用与高分辨率层序的关系。研究结果表明，该方法能极大地提高地层划分与对比精度，是陆相层序地层研究的有效方法。此外本方法在储层对比和储层预测方面也是十分有用的 This paper introduces the theory and method of high-resolution sequence stratigraphy based on the elevation of the datum as the driving mechanism. Based on the analysis of sedimentary facies, this method is based on sedimentary volume fractionation and phase-contrast inversion to show the unidirectional migration direction of stowage space, stratum superimposition pattern, elevation and elevation of reference plane, and then the different levels of reference Surface rotation (ie, sequence), and from long-term cycle to short-term spin-by-level comparison. After that, the author uses this method to make a detailed comparison and comparison between the Late Paleozoic coal measures in Datong and Datong, Shanxi Province, clarifying some fuzzy cognitions in the past and discussing the relationship between coal accumulation and high-resolution sequence. The results show that this method can greatly improve the accuracy of stratigraphic division and contrast, and is an effective method for the study of terrestrial sequence stratigraphy. In addition, this method is also very useful in reservoir contrast and reservoir prediction
