Abstract:Source condition is one of important factors in data acquisition of
high-resolution seismic exploration.Effective seismic source and shot
means must be used according to different conditions and exploration
target,so that the seismic wavelets can be generated which have wide
frequency band,strong high-frequency energy and quite good,ability
to counter noises in propagation.It has been shown experimentally
that the use of multiple shot array in which small charge,shallow
hole and short hole spacing are adopted not only improves the high-
frequency contents of effective waves and the frequency band of high
S/N seismic wave but also gives consideration to both mid refiection
energy and deep reflection energy,The use of muitipie shot array
brought fine results of seismic explorations in many areas.
