摘要
中子管靶子的高温释气是限制中子管高温工作性能的重要因素。对于测井中子管而言 ,由于其井下工作的环境特点 ,解决靶子的散热问题尤为困难。文章基于测井用中子管靶子热状态的理论研究及物理分析 ,设计了一种新型散热结构 ,以便提高中了管工作的耐高温性能 ,并且指出了该结构可能推广的应用前景。
High Temperature releasing gas of neutran tube target limits the temperature resisting quality of the tubes. In relation to logging neutran tube,the heat dissipating of target is particularly defficult due to the feature of down hole enviroment. In this paper, based on physics analysis of target heat status for logging neutron tube,a new disspating heat structure has designed. The heat resisting quality of neutran tube is improved and the passible application of the dissipating heat structure is proposed..
