Abstract: Regional shale gas reservoir has different accumulation conditions,lithologies,physical properties,gas bearing properties and organic geochemistry indices,which lead to different hydraulic fracturing treatment strategies.It is necessary to carry out the mini-frac testing before main fracturing,in order to correctly understand the geological characteristics and the aim of main fracturing.Based on the comparison between the key formation parameter indices of a shale gas exploratory well (Well A) and the mature development parameter indices of American shale gas,the shale frac-ability conditions were analyzed,the specific design ideas and scheme for fracturing test were presented,and the mini-frac monitoring results were interpreted and evaluated systematically.The analysis indicated that,the mini-frac of shale gas needs higher pumping rate and larger liquid volume than conventional mini-frac design; the analysis on mini-frac test not only provided parameters required by the main fracturing design,such as reservoir pressure,permeability,fracture closure stress,fracture initiation and extending,but also could be used to judge the shale formation frac-ability and fracture network forming conditions.
