分析和计算表明,桥路衰减的数值不能简单地看作两个终端衰减之和,而与阻波器阻抗、线路阻抗、变电站母线阻抗和邻相同频寄生信号的相位角等参数有关。

The intensity of the ultrasonic wave will increase when the ultrasonic wave is focused by the sound lens in rock stratum.

然而 ,这种方法要受到两个因素的制约:一是增大超声换能器的功率,必然要增大超声换能器的尺寸,这在本身尺寸就很小的油井中是有一定限度的;二是当超声换能器辐射出的超声波的强度过大时,在超声换能器的周围要发生强烈的空化现象,产生大量的气泡,这些气泡将对超声波产生强烈的散射作用,导致超声波的衰减,反而降低超声波在岩层中的传播距离[1] 。
