| 摘 要： | 盐湖沉积不仅是一种重要化工矿产沉积建造 ,还是一种重要的含油气沉积组合 ,其中常常蕴藏有十分丰富的油气资源。但是 ,此类盆地的层序地层学研究起步较晚 ,尤其是对于陆相盐湖盆地更是如此 ,其关键在于国内外的专家学者对盐湖层序的划分与特征了解较少 ,层序地层划分标准不统一。在充分吸收和消化前人研究成果的基础上 ,从当今的盐湖形成理论出发 ,以潜江古盐湖为研究对象 ,讨论了盐湖盆地沉积的层序地层划分标准 ,及层序地层单元基本特征。认为从层序地层的基本控制因素———可容纳空间 (Accommo dationSpace)出发 ,可将盐岩沉积作为盆地水体浓缩的产物———水面下降阶段的沉积代表 ,从而建立起盐湖的层序地层划分标准。

| Abstract: | Saline sediment is not only an important sediment formation of chemical industry but also an important sediment combination of bearing-hydrocarbon, which often contains abundant petroleum resources. But not until lately did the study of sequence stratigraphy of saline basins have its outset placed,especially for that of saline lake basins. The reason is that the division and characteristics of sequence stratigraphy unit are not clear, and the criterion of sequence stratigraphy uncertain to people both home and abroad. Having absorbed adequate research results of home and abroad, and based on modern saline lakes theories, the author discusses the saline sequence division criterion and basic characteristics of sequence stratigraphy units in the Qianjiang ancient saline lake. One the basis of Accommodation Space, the basic controlling factor of sequence stratigraphy development, the author considers saline lake sediment as the evaporating product of basin water-body and deposited representative at the relative fall of the water face, and sets up the division criterion of sequence stratigraphy. |
