borehole axis 中文意思是什麼
borehole axis
解釋
井眼軸線-
When the vertical formation lies outside of the borehole, the effect of the borehole on the acoustic field decreases with the increase of the distance between the formation and the axis of the borehole ; when the source locates on the interface, with the increase of the azimuth of the dipping interface, the transmitted energy of the horizontal component gradually increases, but that of the vertical component decreases
當井外存在徑向分層時，隨著地層界面遠離井軸，對井內聲場的影響減小。 2 、當聲源位於地層界面以上時，隨著地層傾角的增大，水平分量透過地層界面的聲能量是逐漸增大的；垂直分量的透射聲能量卻是減小的。 -
By the theoretical analysis, the temperature profile of the fluid along the borehole axis, and then, the fluid inlet and outlet temperatures can be obtained
