IODP Expedition 301, Hole U1301B - 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.测井数据是井眼周围地层物理特性的原位测量结果，采集分为两类：取芯作业完成后开展的电缆测井（wireline logging），以及钻进过程中进行的随钻测井（Logging-While-Drilling, LWD）。单井采集的数据参数范围（涵盖电阻率、伽马辐射、声波速度、密度、井壁成像等），取决于对应测井项目的科学目标与作业约束条件。
