ODP Leg 202, Hole 1241B - 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属性的原位测量，其采集方式分为两类：一是取芯作业完成后开展的电缆测井（wireline logging），二是钻井过程中进行的随钻测井（Logging-While-Drilling, LWD）。单口井的采集数据涵盖类型（包括电阻率、伽马辐射、声波速度、密度、井眼成像等）取决于科学目标与作业约束条件。
