Experimental Studies on Reduction of Reverse Phase Point in Heavy Crude Oil by Ultrasonic Irradiation

Hua Qiang

Abstract


In order to decrease transportation cost, experimental studies on viscosity reduction of heavy oil-water system and on viscosity changing rules by ultrasonic wave have been carried out. The results show that ultrasonic wave process can reduce reverse phase point of oil-water system, the water-cut decreases from 50%-60% to 20%-30% by ultrasonic wave, oil-water system changes into emulsion oil-in-water or oil floating in water dispersed system, it can reduce the water amount of transportation. And ultrasonic wave has definite impact on component of heavy oil, peak value of heavy oil decreases gradually when power increases, cavitation tends to saturate at a certain power, and component keeps stable essentially.
