Study on the Flow Pattern of Downhole Oil-Water Separator with Different Inlet Patterns

摘要

Downhole Oil-Water Separator (DHOWS) is applied to separate oil from water under the well, separated oil is lifted to ground and output water is injected directly into another level. It is helpful to reduce environmental pollution, and avoid the invalid water cycling. In view of our native status in oil production, DHOWS with different inlet patterns are studied by CFD method and experiment research. The internal flow field distribution is received, and the influences on pressure drop and separation efficiency of the change in inlet channel, such as the length and patterns, are analyzed, which provide significant references for the application in oil fields and structural optimization of DHOWS.
