油气层序地层学研究的若干问题

摘要/Abstract

摘要： 油气层序地层学是在地震地层学、层序地层学、石油地质学基础上发展起来的一门综合性新型边缘学科。它实质上是一种含油气层序分析学, 在等时地层格架内对油气层序进行成因单元分析。它应用地震层序地层、测井层序地层、露头层序地层分析方法, 采用计算机技术和模拟技术研究含油气盆地的地层层序, 进行地层对比、盆地生储盖组合和含油气系统分析, 进而指出有利的油气勘探方向, 特别是非构造油气藏的勘探方向。源于海相含油气盆地的油气层序地层学的基本原理和研究方法,同样也适用于过渡相和陆相含油气盆地。

Abstract: Oil/gas sequence stratigraphy is a new comprehensive borderline subject developed on the basis of seismic stratigraphy, sequence stratigraphy and petroleum geology.In fact, it is an origin unit analysis techniques of oil/gas sequences in isochronal formation framework.It includes methods of seismic, well log and outcrop sequence stratigraphies and can be applied to study stratigraphy sequences of petroliferous basin combined with computer and simulation techniques, make a stratigraphic correlation and analysis of the source-reservoir-cap assemblage and petroliferous system, and further point out favourable oil/gas exploration areas, specially non-structured petroliferous reservoirs.The basic principle and study method of oil/gas sequence stratigraphy in marine facies petroliferous basin are suitable for transitional and terrestrial facies petroliferous basins.

Key words: Oil/gas formation, Sequence stratigraphy, Seismic stratigraphy, Log interpretation, Outcrop, Sequence, Transit environment, Continental basins
