横波速度测井的实验研究

An Experimental Research on Shear Wave Velocity Well Logging

报道了利用偶极声源在充油钢管中激发和接收横波信号的初步实验结果,表明有可能抑制钢管的纵波信号,使横波信号成为首液信号,可直接测定横波在钢管中的传播速度,为设计横波声速测井仪提供了基础资料。

Some preliminary experimental results concerning the shear wave excited and received in an oli-filled steel tube are reported. Dipole acoustic source and receiver are used in the experiment. It is found to reject the compressional signal and let the shear signal become the first arrival in the tube is possible. So the shear wave velocity in the steel tube can be measured directly Can be measured directly. The results are useful for designing shear shear wave velocity well logging instruments.
