ODP Leg 191, Hole 1179D - 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，采集于取芯作业完成后（电缆测井，wireline logging）或钻井过程中（随钻测井，Logging-While-Drilling, LWD）。单口井所采集的数据类型范围（包括电阻率（resistivity）、伽马射线（gamma radiation）、声波速度（velocity）、密度（density）、井壁成像测井（borehole images）等）取决于科学目标与作业约束条件。
