IODP Expedition 368, Hole U1501D - Well Logging Data

Logging data are measurements of physical properties of the formation surrounding a borehole, acquired in situ after completion of coring (wireline logging) or during drilling (Logging-While-Drilling, LWD). The range of data (resistivity, gamma radiation, velocity, density, borehole images,…) in any hole depends on the scientific objectives and operational constraints.测井数据（Logging data）指井眼周围地层的物理属性测量值，采集于取心作业完成后（电缆测井，Wireline Logging）或钻井过程中（随钻测井，Logging-While-Drilling, LWD）。任一井眼所采集的数据范围（涵盖电阻率、伽马辐射、速度、密度、井眼成像等）均取决于科学目标与作业约束条件。
