Abstract

According to figure of faults distribution in the bottom of Minghuazhen formation of nanpu sag, self-similarity of fault spatial distribution has  been examined by using fractal theory and the fractal dimension of capacity. Correlation coefficients are between 0.99 and 1, which suggests that faults are  fractal structure. The fractal dimension of capacity(D0) in different areas have been calculated and its isoline map is drawn. Author find that the  three of four oilfield are located in the areas where the fractal dimension of capacity are larger than 1.18, which show that the distribution of the fractal  dimension relates to the distribution of oilfield. So Beipuxi fault zone, nanpu fault zone and getuo fault zone are ascertained as the favorable areas.

Key words: Fractal; Fault; Nanpu sag.
