During development of oilfield,near wellbore formation plugging caused by pollution is becoming more and more serious because of drilling, well completion, workover and production etc.High negative pressure compound deplugging technology can effectively remove formation plugging pollution problems to restore the percolation ability of reservoir, and increase oil production of single well. Inthis paper, principle and pipe string structure of the high negative pressure compound deplugging technology were introduced as well as its application in Shuguang oilfield.
