    摘要:

    为了提升油气井用爆破器材的耐温性能、安全性和可靠性,开展了三乙烯二胺/乙二胺高氯酸盐共晶炸药(简称SY)在油气井用爆破器材中的应用可行性试验研究。研究结果表明:SY药剂火工品极限耐温指标约为220℃/120h;SY药剂雷管耐温试验前后的轴向输出均满足工业雷管输出炸孔的要求;SY药剂传爆管耐温试验前后的极限传爆距离约为200mm;SY药剂导爆索高温试验前平均爆速为6 182m/s,高温试验后平均爆速为5 175m/s,均未满足行业要求;SY射孔弹耐温试验前的钢靶平均穿深为185mm,但经过耐温试验后,其穿深性能下降16.5%。

    Abstract:

    To improve temperature-resistant, safety and reliability of blasting equipment for oil field, the preliminary study on the application of triethylenediamine/ethylenediamine perchlorate salt cocrystal explosive(SY) in blasting equipment was carried out by test. The test results show that the maximum of temperature-resistant of SY is around 220℃/120h, the axial output of detonator charged SY before or after high temperature test attains the requirement of industrial detonator standard. Booster charged SY has the maximum detonation distance about 200mm. Detonation speed of some SY detonating fuse is 6 181 m/s and 5 174m/s before or after high temperature test of 220℃ for 120h, which don’t meet the industrial requirement. Some SY shaped charge has 185mm of penetration depth in the steel plate before high temperature test of 220℃ for 120h, while its penetration depth is decreased 16.5% after high temperature test of 220℃ for 120h .
