IODP Expedition 318, Hole U1361A - 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测量结果，可在取心作业完成后（电缆测井（wireline logging））或钻井过程中（随钻测井（Logging-While-Drilling, LWD））获取。单井所采集的数据类型（涵盖电阻率、伽马辐射、声波速度、密度、井眼图像等）取决于具体科学目标与作业约束条件。
