Description

Technical field [0001] The invention relates to the technical field of crude oil separation, and is a SAGD produced liquid flash dehydration device, a SAGD produced liquid reverse phase separation device and a SAGD produced liquid reverse phase separation method. Background technique [0002] At present, the dehydration of SAGD produced fluids at home and abroad mainly adopts the method of mixing diluents to obtain a certain oil-water density difference. The traditional process of dehydration, using this method requires mixing a large amount of diluents into the SAGD produced fluids. When the diluent is added to a certain degree, a certain oil-water density difference will be obtained, and then the oil-water separation will remove the water to obtain heavy crude oil. The general mixing amount is 10% to 25% of the mass of the SAGD produced fluid. The dilution used The main agents are diesel, condensate or purified light crude oil. Since the price of diluent is significantly higher...
