ODP Leg 166, Hole 1007C - 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（borehole）周围地层（formation）物理特性的原位（in situ）测量结果，可在取心（coring）作业完成后通过电缆测井（wireline logging）采集，或在钻井过程中通过随钻测井（Logging-While-Drilling, LWD）获取。任一井眼的数据覆盖范围（涵盖电阻率（resistivity）、伽马辐射（gamma radiation）、声波速度（velocity）、密度（density）、井眼成像测井（borehole images）等），取决于其对应的科学目标与作业约束条件。
