DSDP Leg 66, Hole 492B - 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，可在取心作业完成后通过电缆测井（Wireline Logging）采集，亦可在钻井过程中通过随钻测井（Logging-While-Drilling, LWD）采集。任一井眼所采集的数据类型（电阻率（Resistivity）、伽马辐射（Gamma Radiation）、声波速度（Velocity）、密度（Density）、井眼成像（Borehole Images）等），均取决于该井的科学目标与作业约束条件。
