摘　　要：针对近期在四川油气田若干井次的施工中出现不完全射孔的现象进行了分析和试验,找出了射孔施工起爆率不能达到100%的主要影响原因,提出了相应的应对措施:加强射孔弹与射孔枪的匹配设计以避免装配过程导爆索受损,保证导爆索装配完成后处于绷直状态,选择合适感度的传爆药,优化压药工艺,降低传爆药压药密度,严格控制射孔弹装枪质量,提高导爆索本身质量,这些措施对有效提高射孔弹起爆率是很有必要的。Analysis and experiment were carried out aiming at clarifying the phenomenon of several incomplete perforations appearing recently in Sichuan Oilfield. The main mason that the initiation ratio of the perforation could not reach 100% was figured out. The corresponding measures were propounded： for example, improving the matching design of perforating charges and guns to avoid the breakage of detonating cord when loading, ensuring the detonating cord straight after the assembling, choosing the booster explosive with appropriate sensitivity, optimizing the parameters of perforating charges loading, reducing the density of booster explosive, strictly controlling the assemole of perforating charges and guns, and improving the quality of the detonating cord. All of these proposals would be necessary for increasing the detonation ratio of perforating charge.
