Apparatus and method for downhole fluid separation

摘要

This disclosure concerns a static oil/water separation chamber that is installed in a well extending to an underaround production formation containing hydrocarbon oil and water. The separation chamber has an inlet for receiving well fluid from a section below the separation chamber and two outlets. One outlet discharges a water-enriched component into a discharge well section, and the other outlet produces an oil-enriched component. The height of the separation chamber is larger than the thickness of the dispersion band that is formed under normal operating conditions.
