| 摘 要： | 为了研究油井各参数对超声波透射系数的影响，根据超声波在媒质中的波函数和边界条件，求出了油井中超声波的透射系数。当井液和水泥层的声速和密度增大时，超声波的透射系数也随之增大，但变化幅度不大，特别是水泥层密度对超声波的透射系数影响很小；当岩层的声速增大时，超声波的透射系数会出现一个极大值；岩层密度对超声波的透射系数影响较大，且随岩层密度的增大超声波的透射系数随之降低。

| Abstract: | According to the wave functions and the boundary conditions,the ultrasonic transmission coefficient in oil well was deduced to study the influence of oil well parameters on the ultrasonic transmission coefficient.It was educed that the ultrasonic transmission coefficient increases on the small side with the increase of the density and the sound speed of the well liquid and the cement stratum.The ultrasonic transmission coefficient vary very small especially with the increase of the density of the cement stratum.A maximum of the ultrasonic transmission coefficient exits when the sound speed of the rock stratum increases.The ultrasonic transmission coefficient reduces obviously with the increase of the density of the rock stratum.The article discussed the effect of the density and the sound speed of the well liquid,cement stratum and the rock stratum on the ultrasonic transmission coefficient. |
