摘　　要：燃气式超正压复合射孔是利用火药燃烧产生大量气体,形成瞬时高压,然后再射孔的一种"先压裂后射孔"的射孔方式。其助射作用提高高温高压气体能量利用率,造缝作用增加近井地带泄油面积和流动效率。该工艺可实现隔层同时施工,简化施工工艺,提高完井效率,射孔弹爆破形成的巨大冲击,提高了近井地带地层渗透率,起到了解堵作用。The technology of super over-balance pressure combining perforation by burning gas is a manner to use powder to produce a great deal of high pressure gas simultaneously and then to perforate which termed fracture first and perforation after. Its benefit for helping perforation can raise the used rate of high p & t gas and its advantage for producing gaps can raise out oil area near well bore and flowing efficiency. This technique makes true the operation of interval layers in the same time, simple procedures and develops completed well efficiency. The giant pounds aroused by the charge explosive can rise up formation permeability near well bore and has broken plug usefulness.
