A new method for the ultrasonic enhancement of oil recovery from failing wells is described. The technology involves lowering a source of power ultrasound to the bottom of the well either for a short treatment before removal or as a permanent placement for intermittent use. In wells where the permeability is above 20 mD and the porosity is greater than 15% ultrasonic treatment can increase oil production by up to 50% and in some cases even more. For wells of lower permeability and porosity ultrasonic treatment alone is less successful but high production rates can be achieved when ultrasound is applied in conjunction with chemicals. An average productivity increase of nearly 3 fold can be achieved for this type of production well using the combined ultrasound with chemical treatment technology.
描述了一种从衰竭油井中提高采油率的超声强化新方法。该技术包括将功率超声源降低到井底，要么进行短暂处理后再取出，要么作为间歇使用的永久装置。在渗透率高于 20mD 且孔隙度大于 15%的油井中，超声处理可将产油量提高多达 50%，在某些情况下甚至更多。对于渗透率和孔隙度较低的油井，单独使用超声处理效果较差，但当超声处理与化学物质联合使用时，可以实现较高的产率。对于这种类型的生产井，使用联合超声与化学处理技术可将平均产能提高近 3 倍。
