ODP Leg 123, Hole 765C - 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.

测井数据为井眼周围地层物理性质的原位实测数据，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）获取。单井采集的数据涵盖电阻率、伽马辐射、声波速度、密度、井眼成像测井等类型，具体数据范围取决于科学目标与作业约束条件。
