Optimization and control on separate well and separate zone polymer flooding

In accordance with the complexity of geologic environment in oil fields, the paper presents an optimization model of separate well and separate zone polymer flooding, in which many factors are taken into account, such as the water content of the producing well, polymer injection rate, injection-production ratio, water absorbing capacity, etc. From these factors, constrains are given, and the model is founded and thus realizes the optimization and optimal control on separate well and separate zone polymer flooding. In addition, field application results are provided showing that the model is both practical and advanced.
