Several key factors influencing on the booster tube for oil and gas wells were discussed in this paper, such as booster tube bottom thickness, the space of booster tubes, the charge density, temperature, the types of charge and the axial offset. The boosting effect goes better as the charge density increases in a certain range, but if this density is above a reasonable range, the boosting effect will go worse obviously. The thicker the booster tube bottom, the more attenuation of the explosion wave; and if this thickness is up to a certain limit, the tube will not be detonated. The larger the tube space, the less explosion energy the tube will receive, so, the tube will not be effectively detonated, too. After 160 'C/48 h higher temperature test, the booster tube space is clearly shortened to be 60% of that at normal temperature. When the time is 60 h, the boosting effect further reduces. The booster tube with Pb(N3)2 at the mouth and HMX at the bottom has better boosting effect than the tube that only has HMX. If the axial offset between the two tubes is above 6 mm, the tube will not boost, therefore, the offset must not be too large.%探讨了影响油气井用传爆管性能的几个主要因素,主要包括传爆管底部厚度、传爆管间距、装药密度、温度、装药类型和轴向偏移距离的影响,综合考虑各种因素的影响.传爆管传爆效果在一定范围内随着装药密度增大而提升,密度超过一定范围时起爆效果下降明显；传爆管底部厚度越厚对爆轰波的衰减越大,达到一定厚度时不能引爆传爆管；传爆管的间距越大被传爆的传爆管所接收的爆轰能量越少,不能有效引爆传爆管.经过160℃/48 h高温试验后传爆管的传爆距离缩短明显,是常温下的60％；时间增加到60 h时传爆效果进一步减弱；口部装Pb( N3)2、底部装HMX的传爆管比纯装HMX药的传爆管传爆效果好；轴向偏移距离达到一定程度后不能有效传爆,施工过程中应避免轴向偏移距离过大.
