Phase method of crosswell profiling using coherent SH waves
Tóm tắt
The results of an experiment on crosswell profiling using the coherent downhole source of SH waves are presented. Seismic records were obtained during stationary disposal of the source and varying depths of the vector receiver position. The source coherence made it possible to accumulate signals, thus sub-stantially improving the quality of seismograms and measuring phases. These procedures allowed low-contrasting boundaries between layers to be distinguished. The performed digital modeling confirmed the measurement results.
