摘要
对流体-流体模型的裸眼井中可能存在的声场进行理论分析与数值计算,得出井内全波是由滑行p波、简正波和漏模式波组成的.证实了简正波的存在,澄清有关流-固模型慢地层情况下不存在简正波的结论,得出广义上的慢地层概念及发现漏模式存在的范围和规律.
The present paper covers the theoretical analysis and numerical computation of the acoustic wave in the fluidmodel borehole and it cones to the significant conclusion that the full wave of the inner well consists of gliding p wave, normal wave and leaky wave. This paper demonstrates the existence of the normal mode, it has been made clear that there is not the normal mode under the situation of the fluidsolid mode of slow stratum, and the popularized conception of slow stratum has been obtained and the range and the rule of leaky mode existence have been found .
