Abstract:In order to solve complex problems of traditional methods used to evaluate the rock fracability, the relationship between fractal dimension, rock brittleness and fracture density these three parameters was studied. The multiple linear regression is reasonable through nine kinds cores. The regression coefficients demonstrate both rock brittleness and surface fracture density play positive roles on fractal dimension value, the larger they are, the better the fracability. Therefore, the two parameters can be conv… Show more
