摘　　要：利用R/S分析法对胜坨油田坨715井和坨711井层序地层单元内部进行了相关性的分析,发现在准层序组内部R/S曲线呈线性特征,表明其具有一定的线性相关性。这种相关性的实质是其内部具有一种自仿射分形结构。文中还进一步讨论了这种自仿射结构的成因,认为在各级层序地层单元中均具有这种分形结构。这种层序单元的结构特征揭示了层序内部的本质规律,对层序单元变化特征的预测以及层序地层演化的模拟都有着重要的现实意义。The relativity in the units of sequence stratigraphy of Well Tuo715 and Well Tuo711 in ShengTuo Oilfield is analyzed by R/S analysis. The curve of R/S in interior of parasequence set is shown as linear indicating its relativity. In essence, this relativity shows a self-affine fractal structure. This is further discussed in the paper to the generation of this structure and be considered it existence in the units of sequence stratigraphy in each level. The structure of unit of sequence stratigraphy unveil its inbeing law, so it has important realistic meaning to the forecast of the transformation in the units of sequence stratigraphy and the simulation of the evolvement of sequence stratigraphy.
