    • Abstract
  • The paper introduced the principle of the application of coal reservoir permeability prediction method based on maximum principle curvature attribute of 3D seismic and predicted the structural fractures by using maximum principal curvature attribute of 3D seismic along layer. Through analyzing the mathematical function relation of the fracture interval, principle curvature, coalbed thickness and the fracture permeability, the calculation model of coal reservoir permeability prediction based on maximum principle curvature has been established. The permeability values derived from maximum principle curvature has fit well to the permeability values derived from well logs and coal samples. This study has shown that the permeability prediction method based on maximum curvature is feasible and effective to predict the coal reservoir permeability.
