Abstract: Permeability drop down gradually with the decrease of reservoir pressure in the process of developing of pressure sensitive reservoir. The oil well production and development effectiveness were affected. In order to quantify the influence of variety of formation pressure. Starting from the experimental data, the relationship between permeability and reservoir pressure was obtained. The restored regularity of permeability and oil well production in process of varying of reservoir pressure were researched on combining the oilfield development practice. The effectiveness of advanced water injection in process of development of pressure sensitive reservoir were studied.
