Abstract: This paper dtals wilh the major mechanism of acoustic oil recovery and the results of experimental stady carried out by authors. These major mechanism are that ultrasound wave can reduce crude oil viscosity, solidification point, resistance of oil flow passing through the choke and heat-sound wave oil production, and ultrasound can prevent paraffin from depositiong etc some features of accourfic oil production are analysed and studied also.
