    摘要: A technique for continuous gravity separation of a produced oil and water emulsion has particular utility in separating water for reinjection during a waterflood secondary recovery operation without loss of saleable oil. The method employs a flow direction means to introduce the produced oil-water emulsion into a large volume settling tank substantially tangential to the tank wall and then withdraws the separated oil and water. The apparatus of the instant invention comprises: (a) a tank, (b) an oil-water inlet means, (c) a flow direction means connected to the oil-water inlet means to direct the oil-water emulsion into the settling tank tangential to the tank wall, (d) a bottom-center located water outlet pipe, and (e) an oil outlet pipe.
