摘要
射孔完井是目前国内外使用最广泛的一种完井方法,目前射孔枪管通常为一次性使用,一旦经过射孔作业,多数做报废或降级处理,造成很大的浪费,因此对射孔枪进行再修复制造十分必要。通过对射孔枪管体的结构分析,开发设计了射孔枪体和补贴片的新结构,采用焊条电弧焊打底,φ(Ar)80%+φ(CO2)20%气体保护焊填充和盖面,模拟实际井下条件检测射孔枪管耐压性。结果表明,优化的废旧射孔枪管体结构和补贴片的设计使接头焊接质量达到设计要求指标。
Perforated completion has been widely applied in oilfields at home and abroad. But the perforating banal is usually single-use, once after perforating operation,most of them will be scraped or demoted,which causes great waste,so it is yen＇ necessary to repair and remanufacture the perforating gun. A new structure is designed for perforating gun and subsidies piece based on barrel structure analysis and theorefical calculatiou Taking manual an： welding as backing welding,φ（Ar）80%＋φ（CO2）20% gas shiehled wehting as fill and cosmetic wehling,and the pressure resistance of perforating gun barrel is detected by simulating actual working conditions. The results show that the optimized scrap perforating gun barrel structure and subsudies piece make the quality of welded joints completely meet the design and technology demands.
