ABSTRACT
In this study, fractal-like tree branching model is adopted to study the distribution of natural fractures in the reservoir, treating matrix-fracture as the equivalent continuum model to characterize the fracture volume factor and effective permeability of fractured zones. Based on mass and energy balance equations, considering the impact of natural fractures, mathematical models for non-isothermal heating radius of steam stimulation in fractured heavy oil reservoir were established and analytical solutions were obtained to provide temperature distribution. Numerical analysis shows that heating radius of the model derived here is larger than that of conventional model without considering fractures. Besides, the increase of fractal dimension of fracture and tortuosity lead to heating radius increasing, due to fracture volume fraction and equivalent permeability increasing.
