ODP Leg 115, Hole 715A - 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特性的原位实测数据，采集时机包括取芯作业完成后（电缆测井，wireline logging）或钻井过程中（随钻测井，Logging-While-Drilling, LWD）。单口井的数据覆盖范围（包含电阻率、伽马辐射、声波速度、密度、井眼成像测井等）取决于具体科学目标与作业约束条件。
