IODP Expedition 310, Hole M0009B - 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围地层物理性质的原位测量，可在取芯作业完成后通过电缆测井（wireline logging）获取，亦可在钻井过程中通过随钻测井（Logging-While-Drilling, LWD）采集。单口井可采集的测井数据类型（涵盖电阻率、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。
