摘要：
针对目前国内油气井下电雷管含敏感药而导致的诸多安全隐患,通过分析冲击片雷管的结构、起爆机理以及实际应用环境,开展专用于油气井下的冲击片雷管起爆技术研究。根据冲击片雷管的起爆要求,对可提供5 000 V直流电的脉冲功率源进行原理分析及结构设计;建立冲击片雷管起爆回路的数学模型,分析影响雷管起爆的两个重要元器件储能电容和开关管的相关参数及特性并对器件的选择提出建议。测试实验表明:该起爆系统能适应油气井下的高温环境,并能达到冲击片雷管的起爆要求,可为今后国内冲击片雷管在民用领域的推广提供技术参考。

Abstract: The exploding foil detonator initiating technology dedicated to oil and gas wells, such as its structure, initiating mechanism and practical application environments, has been studied to eliminate the hidden dangers caused by the electric detonator with sensitive agents use in domestic oil and gas wells. According to the initiation requirements of the exploding foil initiator, the principle and structure of the pulse power source for 5 000 V direct current has been analyzed and designed. A mathematical model for exploding foil detonator initiating circuit has been established to study the parameters and the features related to the energy storage capacitor and the switch tube of two important components and recommendations have been proposed for device selection. The Experimental results show that this system is adaptable to the underground high temperature environment and can meet the initiation requirement of the exploding foil detonator. The studies can provide a technical reference for promoting home-made exploding foil detonators in civilian areas.
