| 摘 要： | 高精度层序地层分析以三级层序内高精度的层序地层单元的划分和对比为主要目的 ,它可为沉积体系的沉积构成和油气储、盖组合等研究提供精细的地层对比框架。从滨浅海至陆相湖盆的充填分析均表明 ,三级层序内可依据高频的海 (湖 )泛面或沉积基准面的变化划分出若干高精度的层序地层单元 ,包括四、五级层序以及低位、水进、高位及下降等 4个体系域。四级层序的识别和对比是建立高精度层序地层格架的关键。在煤、油气盆地中 ,四级层序是对储集体和聚煤作用进行分析的基本地层单元

| Abstract: | The major purpose of high resolution sequence stratigraphy analysis is to recognize and correlate high resolution sequences and to construct a chronostratigraphic framework for analysis and prediction of facies and reservoirs. Studies on depositional sequences in shallow marine and inland basins have illustrated that the high resolution sequences, including the fourth and fifth order sequences and lowstand, transgressive, highstand and falling systems tracts, can be usually identified and correlated in the basins in terms of high frequency marine/lake level or base level change. The key in establishing of high resolution sequence framework is the identification and correlation of the fourth order sequences. They are the basic stratigraphic units for analysis of reservoir distribution and coal accumulation in sedimentary basins. |
