摘要： 针对裂缝整体分布规律这一制约碳酸盐岩储集层三维地质建模的瓶颈难题，结合实地露头考察,描述和分析了轮南古潜山碳酸盐岩储集层裂缝形态和分布的自相似特征，建立了岩体裂缝分形统计方法和分维数计算方法,在对轮南古潜山岩体不同尺度网格分形统计的基础上作出了各岩体样本裂缝分布的分形曲线,最终得到了预测轮南古潜山岩体裂缝分布的分形定量公式,为建立轮南古潜山碳酸盐岩储集层渗流空间模型和渗透率参数模型奠定了坚实的基础。

Abstract: The 3D geologic modeling for Lunnan buried hill carbonate reservoir is based on the fractural distribution and the outerop survey. The self-similar feature of the fractural style and distribution in this carbonate reservoir is described and analyzed. The procedure of the fractal geometric statistics of the fracture distribution and the calculation method of the fractal dimension are established. The fractal curves of the fractural distribution of the outcrop specimens are plotted based on the fractal geometric statistics of the buried hill body in different grid sizes. Finally, the quantitative fractal geometric formula for predicting the fractural distribution of the body is provided, which could be as a solid base for the seepage space modeling and the permeability geologic modeling in this carbonate reservoir.

Key words: Lunnan ancient buried hill, carbonate reservoir, fracture, distribution, self similarity, fractal geometrie character, geologic modeling
