Abstract: Combining the jet oscillation treatment with hydraulic fracturing, the new fracturing technique changes static fracturing into continuous dynamic sand fracturing. It can lower operation pressure, increase sanding rate, decrease fracturing fluid volume, and improving fracturing results. This paper introduces the developing history of jet oscillation fracturing technique at home and abroad. It also introduces, the technical property and structure, working theory, operation technology and field test on the jet oscillation fracturing. Testing results show that it has a wide prospect because of simple operation method and low operation cost.
