IODP Expedition 368, Hole U1505C - 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.测井数据是对井眼周缘地层物理性质的原位测量，分别于取芯作业完成后（电缆测井，Wireline Logging）或钻井过程中（随钻测井，Logging-While-Drilling, LWD）采集。任一井眼所采集的数据类型（包括电阻率、伽马辐射、声波速度、密度、井壁成像等）均取决于其科学目标与作业约束条件。
