ODP Leg 128, Hole 794D - 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特性的测量结果，系在取心作业完成后通过电缆测井（wireline logging），或钻进过程中通过随钻测井（Logging-While-Drilling，LWD）原位采集所得。任一井眼所采集的数据涵盖的参数类型（包括电阻率、伽马辐射、声波速度、密度、井眼成像等），取决于其科学目标与作业约束条件。
