IODP Expedition 391 Rig instrumentation

Operational rig information data were measured using a variety of sensors and compiled using the RigWatch software package. Approximately 50 channels of drilling/coring data are captured in real time during the expedition. Data are presented as ASCII files extracted from the proprietary RigWatch data files and are presented by expedition. RigWatch data in time or depth domain can be imported into graphics and analysis programs to be merged and correlated with core physical properties data to enhance assessment of poor core recovery intervals.本数据集通过各类传感器采集钻机作业信息，并依托RigWatch软件包（RigWatch）完成数据整合。本次勘探作业期间，可实时采集约50路钻井/取芯相关数据。数据集以ASCII文件形式提供，此类文件均从专有格式的RigWatch原始数据文件中提取，并按勘探作业批次进行归档。可将时域或深度域下的RigWatch数据导入至图形绘制与分析程序中，与岩心物理属性数据开展融合与关联分析，以此提升对岩心收获率较低层段的评估精度。
