Study and field application of acoustic assistant drainage and broken-down technology

Due to damage and sanding of formation,oil productivity was severely affected.The applicability of conventional flowing technology with gassy water is very limited.The effect of broken-down is not very satisfied.Combine Acoustic Assistant broken-down with gassy water drainage.Through the common function of acoustic vibration and flowing with gassy water,the sweeping areas are enlarged,at the same time,the back-drainage of the formation is strengthened,which makes the ultimate effect of broken-down is improved.This technology has been widely applied in 29 wells of Gudao oilfield,the technology is obviously better than that of the conventional.It has a good effect on new wells with long time shut-in and low productivity.
