摘　　要：通过射孔弹装药结构设计,调整作用在药型罩上的爆轰波压合角及充分利用壳体产生的二次反射波;采用多锥内母线的药型罩结构,优化射流的速度和质量分布;使用自清洁药型罩配方,增加射孔孔道的直径和清除压实带的影响,从而获得符合硬地层油气开发的射孔弹,并在油田应用获得理想效果。It is a design and application that a new auto-cleaning shaped-charge for hard-formation in oil&gas development that was designed by adjusting detonation wave and material formula of liner,we got a good application in oil&gas development.
