Effective Ways for Improving Development Efficiency of Qlaokou Oilfield

Qiaokou Oilfield in Dongpu depression is a serious heterogeneous fault block reservoir. Through studying remaining oil distribution and tapping the potential with the core of accurate reservoir description, comprehensive preventive techniques of water controlling and oil stabilizing such as dual target directional well design and drilling, water finding and plugging are used, thus integral water bearing rate reduces year by year,oil production is basically stabilized.
