Abstract: Combined perforating is joint operation of perforation and high energy gas fracture,with such advantages as big drilling depth,multiple fractures and greatly enlarging seepage area in the near well area.Therefore,analysis and research on feasibility of combined perforating technology in Wang 541 district is done from theoretical foundation of combined perforating.It shows that reservoir in E3s block is with high quartz content and has good pore-throat homogeneity.Therefore,application of combined perforating technology is good for ensuring stability of hole,pore throat and fracturing fracture.Comparing application effects of combined perforating with conventional perforating,it concludes that,combined perforating technology is of higher popularization and application value if the selection of block is reasonable.
