ODP Leg 166, Hole 1006A - 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.测井数据为井眼周缘地层物理性质的实测数据，可于取心作业完成后（电缆测井，wireline logging）或钻井作业过程中（随钻测井，Logging-While-Drilling, LWD）原位采集获取。任一井眼所采集的数据类型（涵盖电阻率（resistivity）、伽马辐射（gamma radiation）、声波速度（velocity）、密度（density）、井壁成像测井（borehole images）等）的覆盖范围，取决于其科学目标与作业约束条件。
