Abstract
To enhance the ultimate recovery factor of Chang 4+5 reservoir in the studied area and realize stabilizing oil production and controlling water cut,the reasonable formation pressure,flow pressure,injection-production ratio and the highest well-head injection pressure are determined by the analysis of the production data,the pressure testing data and other related data over the years.And the development measures are improved:properly reducing injection-production ratio and formation pressure,carrying out cyclic waterflooding tests to delaying the water breakthrough of oil wells,developing regional chemical profile-control tests to control the water breakthroug of oil wells,implementing acidizing plugging removal to improve the output of oil wells,and so on.These measures provide guarantee for stabilizing oil production and controlling water cut of the reservoir.
