Abstract

Slightly Alkaline-Surfactant-Polymer flooding in the development process of the second oil reservoir of Daqing Oilfield had strong injection and production capability and high production rate, but dynamic response and adjustment method of each well group in different effective stages had differences. According to the development characteristics of the B area of the second class reservoir and dynamic characteristics of oil wells in different period, for unbalanced response problems of single well group, in-depth analysed the main contradiction of the effective phases, formed a comprehensive adjustment mode with injection scheme adjustment of "increasing viscosity by gradient" equilibrium,supplemented by fracturing of production well and injection well and optimization of displacement scheme and other adjustment technology.In order to further expand the swept volume, improved the producing status of middle and low permeability layers and achieved a better effect of development.
