Relationship of Three Rock Parameters

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 converted to consider only one parameter that is the fractal dimension of rock. The larger the fractal dimension, the better the fracability is, that is using fractal dimension represents brittle index and surface density to participate in fracability evaluation.
