Keyword:  石油射孔油气井火药热分解特性高温性能研究方法;
Abstract: 采用经典火药热分解理论分析油气井用火药在高温环境下的性能变化规律,针对油气井油层作业段高温、高压以及相对密闭的特殊环境条件,提出了一套较为系统的火药耐高温实验装置和实验方法、火药燃烧性能检测装置和检测方法以及火药的耐高温性能分析方法.对几种与油气井常用的火药组分相类似的火药进行了系统的耐高温性能实验和分析,实验和分析结果表明火药在高温条件下燃速加快,峰值压力增高,影响施工作业的安全性;高温条件下火药能量降低,甚至失效,影响施工作业效果.了解火药在高温环境下的性能变化规律,对进一步探索和建立油气井用火药的性能检测方法起到一定的借鉴作用.
