摘　　要：运用分形几何学理论和研究方法对饮马河大榆树林点坝侧积泥层分布规律进行了研究。研究表明，点坝侧积泥层分布具有分形特征，点坝不同方向、点坝内不同侧积体之间以及同一侧积体不同部位，侧积泥层的分维值不同，揭示点坝储层具有较强非均质性。Distribution regularity of Dayushulin point bar lateral accretion shale beds of Yinmahe River is studied by using fractal geometry theory and research method in this paper. Research result shows the distribution of point bar lateral accretion shale beds have fractal characteristics. The fractal dimension values of lateral accretion shale beds are different in different positions and directions of the same lateral accretion body and among different lateral accretion bodies of the point bar. The above result shows that point bar reservoirs have strong heterogeneity
