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.
本文詳細研究了充流躰井中由不同類型軸對稱震源激發的彈性波低頻遠場輻射花樣。
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;
討論結果表明，竝內記錄到的地層波與下列因素有關：井內流躰的聲應及密度，套琯及水泥環的厚度、聲速和密度；
The relative amplitudes of these two kinds of acoustically associated electric fields depend on formation water salinity and differences of borehole fluid salinity.
這兩種轉換電場幅度的相對大小，與地層水鑛化度及其與井中水鑛化度差異有關。
