| 摘 要： | 以井外流体声波速度小于井内流体声波速度的情况为例,对流体-流体模型裸眼井中声场函数实极点的存在范围进行讨论,计算结果表明只有当轴向波数介于井内流体波数和井外流体波数之间时,声场函数才存在实极点.

| Abstract: | A fluid-fluid model is studied.When the acoustic velocity out of a borehole is lower than the acoustic velocity in the borehole,the existence range of real poles is discussed.The results indicate that: only when the wave number along the axis is smaller than the wave number in the borehole and bigger than the wave number out of the borehole,the real poles exist. |
