ODP Leg 115, Hole 707C - 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）是井孔周围地层物理性质的测量值，可在取心作业完成后通过电缆测井（wireline logging）方式、或钻进过程中通过随钻测井（Logging-While-Drilling, LWD）方式原位采集得到。任一井眼所涵盖的数据类型（包括电阻率、伽马辐射、声波速度、密度、井眼图像等）均取决于其科学目标与作业约束条件。
