摘要: 簡(jiǎn)述了油氣井射孔工藝作業(yè)過(guò)程，總結(jié)了射孔工藝參數(shù)對(duì)油氣井產(chǎn)能的影響，分析了國(guó)內(nèi)外射孔槍產(chǎn)品及工藝水平的差距；借鑒兵器工業(yè)技術(shù)和爆炸力學(xué)研究進(jìn)展，闡述了射孔槍管體的材料性能指標(biāo)對(duì)射孔工藝參數(shù)的影響；研究了實(shí)彈射孔后槍身材料大開(kāi)裂時(shí)止裂處斷面形貌，找出了開(kāi)裂的脆性主因；對(duì)比分析了國(guó)內(nèi)外非通孔槍身材料發(fā)展的差異性，介紹不同公司和機(jī)構(gòu)的射孔技術(shù)及產(chǎn)品最新進(jìn)展。此外，介紹了一種新開(kāi)發(fā)的高強(qiáng)韌射孔槍用無(wú)縫鋼管的各項(xiàng)性能。Abstract: Briefed in the essay is the perforating operation in oil & gas well completion.Summerized is the influence of perforation parameters on well productivity.Also analyzed are the difference between domestic and oversea perforating guns as well as the difference between their technological levels.Learning from the research of the technology in ordnance industry and the mechanics of explosion，the effect of material properties of perforating gun on perforating performance is elaborated.The main cause of brittleness at the crack is found by studying the morphology of the crack arrest section at the big crack on the perforating gun body after firing live charges.The difference between domestic and oversea developments on materials for gun body with blind holes is compared and analyzed.The latest perforating technologies and products from different companies are introduced.Furthermore，the properties of a newly-developed type of high strength and toughness seamless steel tube for perforating gun are introduced.
