摘　　要：为提升射流质量,增加射孔穿深性能,根据射流侵彻基本理论,从射流微元形态对侵彻性能影响分析入手,通过对新型装药结构、药型罩结构设计及药型罩配方的研究,大幅提升了炸药利用率,增加了炸药能量对药型罩的有效作用时间;通过对壳体结构的调整,提高与药型罩参数的匹配度,提高了射流质量,使102型射孔器混凝土靶平均穿深提高27%。在大庆油田某区块5口生产井试验应用,平均采液强度比相邻常规射孔弹射孔的井平均采液强度提高显著。新型超深穿透射孔弹的研制可以提高油田采收率,为油田低渗透储层高效开采提供射孔弹新产品和新技术的支持。In order to improve the jet quality and increase the perforation penetration performance,according to the basic theory of jet penetration,this paper optimizes the new charging structure,liner structure design and liner formula after the analysis of the impact of jet micro element shape on the penetration performance,and greatly improves the explosive utilization rate and increases the effective action time of explosive energy on the liner.In addition,by adjusting the shell structure,the matching degree with the liner parameters is improved,the jet quality is improved,and the average penetration depth of 102 perforator in concrete target is increased by 27%.This new perforating charge has been applied to 5 production wells in a block of Daqing Oilfield,and the average liquid production intensity is significantly higher than that of the adjacent wells perforated by conventional perforating charges.The development of new ultra-deep penetrating perforating charges can improve oil recovery and provide support of new products and new technologies for efficient exploitation of low permeability reservoirs.
