ANALYSIS OF APPLIED EFFECTS FOR TWO STAGE HIGH ENEERGY GAS FRACTURING

Two stage high energy gas fracturing (HEGF- S) is a new stimulation technique which has been used in Changqing Oil Field in recent years. It is used for the wells of invalid conventional hydraulic fracturing or serious plugging after hydraulic fracturing. The practices have been proved that the above uses can obtain good fracturing effects. This paper mainly introduces the basic principle, design method of two- stage high energy gas fracturing, and making analysis for spot applied effects.
