Study on eccenter separate layer injection technology of alkaline-surfactant-polymer

In view of applications of alkaline-surfactant-polymer to lower permeability,greater interlamination contradictory and difference, and multi layer situation.Compared and analyzed current separate layer injection technology,provide a new eccenter separate layer injection idea of alkaline-surfactant-polymer,can realize separate layer injection by a special eccenter injection tool.Introduced principles and string architecture of separate layer injection technology,and provided some anti-scale method of this tool.
