【Abstract】 Downhole oil-water separation technique has both economical and environmental benefits, but its application is restricted due to its complicated design, rigorous requirements to candidate wells and high cost. The design of the downhole oil water separation system for submersible electric pump wells is investigated in this paper. The structure and the principle of the system are introduced, and its design calculation method is presented on the basis of the study on its subsystems and the connections among them, which provides the theoretical basis for its application in oilfields. A ground monitoring model is build, it is used for acquiring the downhole status of the system according to surface test data. The model not only provides a means for the control of the system but also reduces the application cost of the downhole oil-water separation technique.更多还原
