IODP Expedition 319, Hole C0010A - 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性质的原位测量结果，采集场景分为取芯作业完成后的电缆测井（wireline logging），以及钻井过程中的随钻测井（Logging-While-Drilling, LWD）。单井所采集的数据类型涵盖电阻率、伽马辐射、声波速度、密度、井眼成像等，其选择取决于科学目标与作业约束条件。
