Abstract：The gas reservoir in Xujiahe formation of Longnvsi structure is characterized with low porosity and low permeability or ultra?鄄low porosity and ultra?鄄low permeability and hydraulic fracturing is the main method of its commissioning and yield increase. However，because of poor physical properties，low reservoir abundance and severe heterogeneity，it is difficult to ensure the fracturing result of this gas reservoir. Analyzed are the characteristics of lithology and physical properties of the gas reservoir，summarized are difficulties of hydraulic fracturing in this area and put forward are a series of such techniques for improving hydraulic fracturing effects as testing fracturing，propping agent slug，quasi?鄄linear sand?鄄adding fracturing and rapid flow?鄄back. Conducted is sand?鄄adding fracturing field test on six wells and the rate of successful stimulation reaches up to 70% and the testing production is 16.78×104m3/d，which lays a foundation for improving the fracturing effect of such gas reservoirs.
