DSDP Leg 46, Hole 396B - 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。每口井的测井数据所覆盖的参数范围（包含电阻率（resistivity）、伽马辐射（gamma radiation）、速度（velocity）、密度（density）、井眼成像（borehole images）等），取决于该井的科学目标与作业约束条件。
