复合射孔技术在现河王541区块的应用

复合射孔将射孔和高能气体压裂联合作业,具有穿入深度大、产生的裂隙多、近井地带的渗流面积大大增加的优点。为此,从复合射孔理论依据出发,分析研究了王541地区应用复合射孔技术的可行性,认为该区块E3s中储层石英含量高,且孔喉均质性好,在该地区应用复合射孔技术有利于保障孔眼孔喉及压裂裂缝的稳定性。通过分析比较常规射孔和复合射孔的应用效果,发现只要区块选择得当,复合射孔技术具有较高的推广应用价值。

Application of combined perforating technology in Xianhe Wang 541 block

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.
