【 摘 要 】

In order to reveal fracture propagation law of low permeability oil reservoir, using RFPA software, a series of simulation models were built. Through numerical simulation, the maximum shear stress, the minimum main stress and pore pressure changes under different water injection pressure were got. The results shown that the process of fracture extension can be divided into three stages: the front stage, the microcrack stage and the rupture stage, the water injection pressure at 25 ∼ 30MPa is the best result. The founding provides important theoretical guidance for low permeability reservoir reconstruction and optimization of well layout in the process of waterflood development.
