Abstract：Practices have shown that comprehensive research techniques for seismic and microseismic monitoring results are very beneficial for the development of unconventional oil and gas reservoirs.Based on the research of 3D seismic fracture pro-perties,combined with microseismic monitoring mapping results and hydraulic fracturing construction data,we analyze in this paper the activities of natural fractures and its impacts during fracturing operation.The results have shown that active natural cracks will affect the geometry of hydraulic fracturing cracks and hydraulic fracturing construction,while non-active natural crack zones have no obvious influence on the distribution and construction of hydraulic fracturing cracks.These results can provide a reference for the optimization of horizontal well trajectory and the adjustment of hydraulic fracturing construction parameters.
