流体-流体模型裸眼井的声场理论分析与数值计算

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.

Acoustic Wave Theory and Numerical Computation of Fluid Fluid Model Borehole

The present paper covers the theoretical analysis and numerical computation of the acoustic wave in the fluid-model bore-hole 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 fluid-solid 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.
