ODP Leg 166, Hole 1007C - 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实测数据，其采集时机分为取芯作业完成后（电缆测井（wireline logging））与钻井过程中（随钻测井（Logging-While-Drilling, LWD））两类。单口井可采集的数据类型范围（包含电阻率、伽马辐射、声波速度、密度、井眼成像等）取决于科学研究目标与作业约束条件。
