Lungu heavy oil was mainly exploited by mixing light oil due to its high viscosity, however, it brings about some other problems (e.g. great demand for light oil, low cost efficiency, high expenses in transportation and processing). The simulation test of artesian flow with the appropriate emulsifier demonstrates Lungu heavy oil can be transformed into pseudo emulsion, and its viscosity decreased from 31 600 to less than 400 mPa•s, with a decreasing rate of 98.7%. The pseudo emulsion has both favorable dynamic stability and dehydrating property.
