摘　　要：层序地层学的层序和储层的流动单元都具有层次性,不同的学者有不同的划分和描述.为了统一从陆相地层层序到储层流动单元的层次结构,并落实到含油气系统、沉积结构单元等具体运用上,根据前人的研究成果,结合个人认识,将陆相层序到储层流动单元的层次结构从大到小依次划分为7个层次:大层序、中层序、层序、亚层序、准层序、小层序和均质段,并较详细论述了这7个层次的成因、特征、意义和应用.Because of the complex hierarchy of sequences stratigraphy and flow units, some researchers divide and describe the heterogeneity in different ways. Now the theory of high-resolution sequence stratigraphy is applied to flow units in reservoirs. Due to division difference from terrigenous sequence stratigraphy to flow units in reservoirs, such study as heterogeneity is some confused. In order to unite the present study results and resolve the confusion, the hierarchy structure from terrigenous sequences stratigraphy and flow units are elaborated and divided into 7 scales: megasequence, mesosequence, sequence, subsequence, parasequece, microsequence and homogeneous field. The genesis, characteristics and meaning of hierarchy structure are discussed and analyzed in combination with application such as petroleum system, an architecture unit, which contributes to the exploration and development of reservoirs.
