IODP Expedition 314, Hole C0003A - 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，可在取芯作业完成后采集（即电缆测井（wireline logging）），或于钻井过程中采集（即随钻测井（Logging-While-Drilling, LWD））。单井所涵盖的数据类型包括电阻率、伽马辐射、声波速度、密度、井眼成像等，其具体范围取决于科学研究目标与作业约束条件。
