| 摘 要： | 准确求得声场函数的极点是声波测井波场分析的重要环节。针对流体-固体裸眼井声场模型,采用牛顿迭代法,计算了井孔声场频散方程的根。通过分析和对比,得出了该模型声场函数极点的变化规律,并给出了其极点实部的求解区域。

| Abstract: | It was important for analysis of the acoustic that the pole of acoustic funtion was calculated exactly.Aimed at the fluid-solid model,Newton iterative method was used to gain the root of the dispersion equation.With analysis and comparison,the changing law of the pole was found,and the existing region of the pole's real part was given. |
