    Abstract
  • There is fractal property in reservior rocks. According to the principle of the fractal geometry, the pore structure can be studied, and the fractal model of the capillary pressure curve and the relative permeability and the pore throat distribution can be set up. But the pore structure can be predicted when the fractal dimension D has been acquired. At present, the fractal dimension is acquired by the scanning electron microscopy. But it is not easy to use it to calculate D. Based on proposed fractal capillary pressure model, the fractal dimension D is predicted by capillary pressure data. The practical data verifies the validity of this method and the method is simpler than scanning electron microscopy.
