Application of Shock Wave Plug-removing Measure in Low-mid Permeability Reservoir

According to the principle of mechanics, hydraulics, chemistry and thermodynamics, the newly developed technique of shock wave may remove formation plugging near wellbore area to increase the permeable capability of the formation and the output of oil wells.With studies of seeping specialty and characteristics of formation damage in low-mid permeability reservoir, shock wave is utilized in GJ, MTZ, WZ oil field.Recently, the field trials were applied at 16 wells and the output increased by 9785t.
