PROCESS FOR RECOVERING HEAVY OIL |
摘要 |
A method for recovering oil includes recovering an oil-water mixture from a well and separating oil from the oil-water mixture to produce an oil product and produced water. The produced water is directed to an evaporator which produces steam that is condensed to form a distillate. Thereafter the distillate is directed to a steam generator and is heated to form steam and water. At least a portion of the water is recirculated through the steam generator. Another portion of the water is mixed with the steam to form a steam-water mixture that is injected into an injection well. |
