摘要
就自生靶和预制靶两种类型的中子管在石油测井高温环境下的寿命问题进行了分析计算 .结果指出 :自生靶中子管比预制靶中子管具有耐高温、高稳定性、长寿命等优点 ,预期寿命为2 0 0 0h以上 .
This paper provides the analysis and calculation for lifetime of two kinds of neutron tube in high temperature environment of petroleum log.The result is that the self driving in target has many advantages than the pre absorbing target, such as: high temperature resistancy, high stability and long lifetime, et. The lifetime is above 2000h, but the yield of the self driving in target neutron tube is lower than the yield of the pre absorbing target neutron tube.
