ODP Leg 191, Hole 1179D - 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）为井眼周围地层的物理性质测量结果，其采集分为两类原位场景：取心作业完成后开展的电缆测井（wireline logging），以及钻井过程中实施的随钻测井（Logging-While-Drilling, LWD）。任一井眼的测井数据覆盖类型（如电阻率、伽马辐射、声波速度、密度、井眼成像等），均取决于该井的科学研究目标与作业约束条件。
