    摘要:

    随着以“慧磁”钻井中靶导向系统为代表的主动磁测技术的不断提升和应用范围的不断扩展,未来将更多应用在地热开发井、深部矿产资源勘探井等高温井中,高温会成为限制仪器在上述领域应用的“瓶颈”问题。为进一步提升“慧磁”系统的耐温性能,提出采用被动热管理方式,通过使用有限元方法对保温筒相变储热特性进行仿真计算,探究了吸热体最佳耦合长度并横向对比控温能力最佳的相变材料,分析了保温筒内部轴向温度和吸热体相态随时间变化情况。结果表明,上吸热体长度400 mm和下吸热体长度250 mm为最佳耦合长度,保温筒在150 ℃下工作6 h后,上吸热体相变潜热利用率96.7%,下吸热体相变潜热利用率70.5%,电路板最低温度63.48 ℃,低熔石蜡控温效果最佳。

    Abstract:

    With the continuous improvement and expansion of the application scope of active magnetic measurement technology represented by SmartMag Drilling Target-Hitting Guide System, it will be more applied in high-temperature underground environments such as geothermal well development and deep-sea mineral resource exploration in the future. High temperature often becomes a bottleneck problem that restricts the normal operation of instruments.In order to further improve the temperature resistance performance of the SmartMag system, this article adopts passive thermal management method and uses finite element method to simulate the phase change heat storage characteristics of the vacuum flask. It explores the optimal coupling length of the heat absorbing body and compares the phase change materials with the best temperature control ability horizontally. It analyzes the changes in axial temperature and phase state of the heat absorbing body inside the vacuum flask over time.The results show that the optimal coupling lengths are 400mm for the upper absorber and 250mm for the lower absorber. After operating the insulation cylinder at 150℃ for 6 hours, the utilization rate of phase change latent heat of the upper absorber is 96.7%, and the utilization rate of phase change latent heat of the lower absorber is 70.5%. The minimum temperature of the circuit board is 63.48℃, and the temperature control effect of low melting paraffin is the best.
