IODP Expedition 371, Hole U1507B - 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）是对井眼周围地层物理特性的原位测量数据，其采集分为两类场景：取芯作业完成后（电缆测井，wireline logging），或钻进过程中（随钻测井，Logging-While-Drilling, LWD）。单井采集的数据类型（涵盖电阻率（resistivity）、伽马辐射（gamma radiation）、声波速度（velocity）、密度（density）、井壁成像（borehole images）等），需依据科学目标与作业约束条件确定。
