Downhole Survey Seismograph With 3 Channels Borehole Geophone
Downhole Survey Seismograph is a geophysical method based on borehole seismic wave acquisition. It is mainly based on vertical seismic profiling (VSP). The seismic data in the well has the advantages of high signal-to-noise ratio, wide frequency band, rich wave field, and obvious seismic wave dynamics and kinematics characteristics.
With the continuous deepening of oil and gas reservoir exploration and development research, borehole seismic technology has received more and more attention as a high-resolution seismic exploration method, because it combines the characteristics of seismic and logging, surface and well data , thus becoming a bridge and link connecting multidisciplinary oil and gas exploration methods
