Based on the geological features of fractured reservoir in C oilfield of Bohai Bay, the data of cores, well logging and outcrop were applied to analyze the origin and characteristics of buried hill fractured reservoir. It is considered that stress field and fault are the two main controlling factors for fracture development. Combined the stress field with fault, a set of discrete fracture network (DFN) models was generated to predict the fracture distribution. Through geological features comparison and dynamic data test, the best DFN model was chosen for C oilfield. Based on the optimized DFN and fracture aperture, the porosity model, permeability model and fracture porosity model were established which provides geological foundation for making more reasonable oilfield development plan.
