DSDP Leg 65, Hole 482C - 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结果，其采集时机为取心作业完成后开展的电缆测井（wireline logging），或钻井过程中开展的随钻测井（Logging-While-Drilling, LWD）。单口井所采用的测井数据类型范围（包括电阻率（resistivity）、伽马辐射（gamma radiation）、声波速度（velocity）、密度（density）、井眼成像测井（borehole images）等）取决于其科学目标与作业约束条件。
