The invention belongs to the technical field of oil and gas field seismic
data processing, and particularly discloses a first arrival prediction method, device and equipment under a complex mountain strong interference background and a medium. The method disclosed by the invention comprises the following steps: acquiring a
surface structure interpretation result of a
test point, the thickness of a low deceleration zone and the elevation of each detection point; thirdly,
smoothing and calculating the elevation of each arranged detection point to obtain a static correction predicted value of each detection point; then, on the basis of single-shot data, loading static correction predicted values of all detection points, and carrying out preliminary first arrival
pickup; and finally, selecting the first arrival data which can be picked up and the
offset distance of each channel, performing multi-segment
linear fitting on the left and right arrangements, and adding with the height-range static correction value of the
reference surface of each channel to obtain a final predicted first arrival value. According to the method, the predicted value of the first
arrival time of each channel is obtained by using the
linear relation function, a basis is provided for accurately picking up the first arrival, and the first arrival picking efficiency and quality are improved. The method can be widely applied to the field of
seismic exploration.
