borehole fluid

基本解释

We detail the far-field radiation patterns of low-frequency elastic waves generated by different axially symmetric sources in fluid filled borehole.
本文详细研究了充流体井中由不同类型轴对称震源激发的弹性波低频远场辐射花样。
The result shows that the formation wave amplitude recorded in borehole is affected by many factors, such as acoustic velocity and density of borehole fluid;
讨论结果表明，并内记录到的地层波与下列因素有关：井内流体的声应及密度，套管及水泥环的厚度、声速和密度；
The relative amplitudes of these two kinds of acoustically associated electric fields depend on formation water salinity and differences of borehole fluid salinity.
这两种转换电场幅度的相对大小，与地层水矿化度及其与井中水矿化度差异有关。
