摘要
根据三个不同的模型.用有限差分法合成跨孔地震波的波场记录.运用这些合成记录详细分析和讨论了地震波在管道附近的波场传播特证,比较了炮点位置、接收点位置.管壁速度,管线缺口对波场的影响.模拟结果有效地指导了实际资料的处理和解释.
Based on three different models .using finite difference method the wave field record of cross-hole seismic wave is synthesized. The paper minutely analyzes and discusses the propagating characteristics of the wave field near pipelines, it compares the effect of the positions of the shot point and receiving point, the pipe wall velocity and pipeline gap upon the wave field. The results of the simulation effectively direct the processing and interpretation of the actual data.
