Abstract

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
