摘要
A kind of process, to determine description in VSP-WD (vertical seismic profiling (VSP)-while drilling preliminary wave absolute time). By combining seismic plane source and having fired complicated earthquake pattern unique temporal (with pinpoint accuracy face-underground time reference system), automatic underground process preliminary wave detects downhole data, or even (low signal-to-noise ratio) is established under severe conditions.
