Analysis of influencing factors on shale gas well productivity

Numerical simulation is conducted based on laboratory test to study the influences of shale reservoir quality and fracture property after fracturing on shale gas production,thus obtained the relationships between influencing factors.The research indicates that fractures on one side can not increase shale gas production;the volume of fractured shale gas reservoir is the key factor affecting productivity;the more the number of fractures is,the bigger the fractured volume is,the more efficient the fracturing stimulation is.
