摘要

 
    

 The pore structure characteristics which tested by bubble pressure method, including many internal and external factors of formation damage, can reflect the flowing distribution of connected throats. The authors use fractal dimension to describe the pore structure and study on the relationship between fractal dimension and formation damage through experiments. The results show that the greater the fractal dimension, the higher water blocking damage and stress sensitivity.
