ODP Leg 201, Hole 1230A - 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性质的原位测量结果，采集方式包括取心作业完成后实施的电缆测井（wireline logging），或钻进过程中开展的随钻测井（Logging-While-Drilling, LWD）。任一井眼的测量数据涵盖范围（包括电阻率、伽马辐射、声波速度、密度、井眼成像等），均取决于其科学目标与作业约束条件。
