ODP Leg 183, Hole 1140A - 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.测井数据是对井眼周围地层物理性质的原位测量值，可在取心作业完成后通过电缆测井（wireline logging）采集，亦可在钻井过程中借助随钻测井（Logging-While-Drilling, LWD）获取。单口井所采集的数据类型覆盖范围（涵盖电阻率、伽马辐射、声波速度、密度、井眼成像等），取决于其科学研究目标与作业约束条件。
