ODP Leg 168, Hole 1032A - 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.测井数据是对井筒周围地层物理性质的原位实测数据，其采集时机分为两类场景：取心作业完成后开展的电缆测井（wireline logging），以及钻井过程中进行的随钻测井（Logging-While-Drilling, LWD）。单井所采集的测井数据类型覆盖范围（包括电阻率、伽马辐射、声波速度、密度、井眼成像测井等），取决于该井的科学目标与作业约束条件。
