常見例句雙語例句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體井中由不同類型軸對稱震源激發(fā)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(jié)果表明,并內(nèi)記錄到的地層波與下列因素有關:井內(nèi)流體的聲應及密度,套管及水泥環(huán)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(zhuǎn)換電場幅度的相對大小,與地層水礦化度及其與井中水礦化度差異有關。 返回 borehole fluid
