Design, Construction, Calibration, and Deployment of the Next Generation of Heat Flow Piston-coring Shoe for Scientific Drilling

这是一个开发新工具的项目，用于测量现场温度，作为科学海洋钻探期间活塞取芯作业的一部分（APC工具）。前两代APC工具在深海钻探项目和大洋钻探计划中有着悠久而富有成效的历史，但综合大洋钻探计划（IODP）需要新的工具。新工具将利用电子和计算能力方面的最新进展，并将提高所获得数据的质量和根据这些测量结果进行解释的质量。前几代APC工具包括安装在活塞岩心切割鞋内的传感器和测井仪包;新开发还将包括设计和创建新的顶部接头，该接头将允许在单个工具下降期间部署两个仪器，从而可以确定热梯度。

This is a project to develop a new tool for use in measuring in-situ temperatures as part of piston coring operations during scientific ocean drilling (an .APC tool.). Two earlier generations of APC tools have had a long and productive history during the Deep Sea Drilling Project and the Ocean Drilling Program, but new tools are needed for the Integrated Ocean Drilling Program (IODP). The new tools will take advantage of recent advances in electronics and computing capabilities and will improve on the quality of acquired data and in interpretations based on these measurements. Previous generations of APC tools have included a sensor and logger package installed within the piston core cutting shoe; the new development will also include design and creation of a new top sub that will permit deployment of two instruments during a single tool lowering, allowing determination of a thermal gradient.
