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

该项目旨在开发一种用于测量现场温度的新工具，作为科学海洋钻探过程中活塞取心作业的一部分。APC的工具)。前两代APC工具在深海钻井项目和海洋钻井项目中有着悠久的生产历史，但综合海洋钻井项目（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基于这些测量的解释。前几代APC工具包括安装在活塞岩心切割鞋内的传感器和记录仪包；新的开发还将包括设计和制造一个新的顶部短节，该短节将允许在一次工具下放期间部署两个仪器，从而确定热梯度。

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.
