Abstract
Some important aspects of power generation using the coproduced hot oil and water from LB reservoir, Huabei oil field were studied. The temperatures of the formation and the produced liquids were about 120°C and 110°C respectively. One of the main differences between geothermal and oil wells is the production rate. Usually the production rate in oil wells is much less than that in geothermal wells. The possibility of significantly increasing the total liquid injection and production rates of the injectors and the oil wells in LB reservoir was investigated. Some pilot tests were conducted in the wells. A 400 kW power generator, which was a binary screw expander system, was installed and put into operation after the feasibility and field studies. Operation data over several months since April 2011 were measured and collected.
