摘　　要：声发射检测技术是指对材料局部能量快速释放而发出瞬态弹性波的检测来判断材料或构件安全可靠性的一种动态无损检测技术。在我国,AET技术在石油钻井井控设备壳体安全评价方面的应用逐渐成熟。新疆某油田科学性引入AET技术对石油钻采用防喷器进行安全测评并取得显著效果,经对检测的防喷器进行系统统计、归类,为油田庞大的在役防喷器群体建立起一个详细的检查表,这为该油田防喷器的返修、定期检查以及延长服役期提供了可靠的参考依据。Acoustic emission test(AET)technology is a dynamic nondestructive examination way and it is used for inspecting the elasticity signal which comes from this material when it releases some energy in local at enough load.AET technology has been used in the safety evaluation of body of petroleum well-control equipment in China.The safety of BOP was tested in Xinjiang oilfield by AET technology and obtained remarkable effect.Through statistical analysis and classify,a detailed record was set up for some inspected BOP.It can provide reference basis for the service,periodic inspection and extend operating life of BOP.
