The development of old Daqing Oilfield has entered the late stage of extra-high water cut, and the situation of inefficient and ineffective circulation is serious. Based only on the static and dynamic geological parameters, it is far from satisfying the requirement of analysis and judgement in the case of that the current well pattern, well spacing and dynamic state have all changed greatly, so the difficulty of development and adjustment is increasing. In this paper, tracer numerical simulation method is used to quantitatively study the directional injection-production rate of injection-production well layers, and the chart of the relationship between liquid production and water cut under different oil prices is established. The benefit types of production layers in production wells are classified and quantitatively evaluated, and then the inefficient and ineffective layers of production wells and their main inflow direction are accurately identified, which provides a basis for water control and efficiency improvement of inefficient and ineffective circulation well layers.
