摘要
本文从柱状井内弹性波的传播理论出发,分析了位于井轴上的多极子声源激发的井内声场中反射纵波和反射横波的远场特性,从理论上指出了利用多极子声源直接进行横波测井的可能性。同时,应用分离波数技术,实际计算了单极子、偶极子和四极子声源激发时的井内远场接收波形,证实了理论分析的结论。
Follwing the theory of the elastic wave propagation,this paper analyses the far field characteristics of p-wave and s-wave excited by a multipole acoustic source in a fluid-filled borehole,and points out the possiblility to carry out the shear wave logging directly.Simultaneously,the separate wave number echnology is used to calculate the recieved waveform received from far field excited by monopole,dipole and quadripole source in a fluid-filled borehole respectively.The numerical results conform with the theoretical results exa- ctly.
