Temperature Logging Tool for Deep, Hot Drill Holes

这项奖励提供50%的资金用于开发一种测井仪器，用于测量深热钻孔中的温度与深度。测井仪器将由南卫理公会大学地质科学系的PI开发。新加坡管理大学承诺提供该项目所需的其余资金。使用目前的设备测量流经地壳的热流在深度和温度方面受到严重限制，这主要是因为使用电缆将热流传回地表。因此，很少有研究质量的温度测井仪可以在超过450K和3公里的条件下使用。该项目将采用井下计算机和低温技术，开发出一种比现有测温仪更准确、工作温度可达650K和5公里的测井仪。需要这样的测量来解释来自地球内部的热流及其在地球热收支中的作用。

This award provides 50% funding for the development of a logging tool for temperature versus depth measurements in deep and hot drillholes. The logging tool will be developed by the PI in the Department of Geological Sciences at Southern Methodist University. SMU is committed to providing the rest of the funding required for this project. Use of present equipment to measure heat flow through the Earth's crust is severely limited in depth and temperature, mainly because of the use of electric cabling to transmit back to the surface. Consequently, few research quality temperature logging tools can be used at more than 450K and 3 kilometers. This project will adapt downhole computer and cryogenic technology to develop a temperature logging tool that is more accurate than existing ones and capable of operating up to 650K and 5 kilometers. Such measurements are needed to interpret the heat flow from the interior and its role in the Earth's thermal budget.
