Dimension, 3-d seismic exploration and vsp logging operation are carried out respectively.Two dimension, exciting of 3-d seismic exploration and exciting again of vsp well logging
Multiple enforcement.Taking a work area operation as a example, in same work area (region), two dimension, 3-d seismic exploration are identical with vsp well logging
Shot point be about 8000 big guns.That is: one times (8000 big guns, cost at least millions of) be both repeated excites workload,
Less economical, waste the double time, efficiency is low, and motivating factor is not single again, be unfavorable for explaining correctly sentencing of contrast
Fixed.
