浅谈陆相盆地高分辨率层序地层研究思路

陆相盆地层序分析已成为地质工作者高度重视的重要研究课题之一。该文从中国中部、东部和西部广泛发育的中新生代陆相含油气盆地层序分析工作中所面临的实际问题出发 ,认为在不同学者提出的层序地层学理论体系中 ,以 T.A.Cross提出的高分辨率层序地层学更适合中国中、新生代陆相盆地层序地层学研究。简要讨论了以地表露头、钻井岩芯与测井和地震剖面为主要分析对象的陆相含油气盆地高分辨率层序地层学的综合研究思路和工作流程。

Research thinking of high-resolution sequence stratigraphy about a terrigenous basin

The sequence analysis of a terrigenous oil gas bearing basin is one of the important courses to which geologists have paid extra attention. In this paper, proceeding from the practice questions which are faced within the sequence analysis of the Meso Cenozoic terrigenous oil gas bearing basins that have spreadly developed in the centre, east and west of China, the authors consider that in the different theoretical systems of sequence stratigraphy, the theory of high resolution sequence stratigraphy which was advanced by Timoty A. Cross is more fit for the sequence research of the Meso Cenozoic terrigenous oil gas bearing basins of China . Taking the cropping, drilling, well logging and seismic data as the main analytic targets, the authors briefly discuss the synthetical research thinking and the technological process of the high resolution sequence stratigraphy applied to the terrigenous oil gas bearing basin.
