Description of Shale Pore Fracture Structure Based on Multi-fractal Theory
Abstract
In order to describe the shale-fissure s structure and distribution accurately, this paper combines with complex features of shale rock mass multilevel micro-scale fissure network, putting forward that utilizing the multi-fractal method to describe the distribution of fissures with different dimensions. By choosing some oil field s block shale samples, obtain the fissure distribution characteristics by CT scanning and calculate with the multi-fractal theory, the results show that the shale rock mass fissure distribute in a multiple-fractal regularity. The study results lay a solid foundation of subsequent press shale fissure network s formation and description.
