METHOD FOR SWELL EFFECT AND MIS-TIE CORRECTION IN HIGH-RESOLUTION SEISMIC DATA USING MULTI-BEAM Echo SOUNDER DATA

摘要

Provided is a method for swell effect and mis-tie correction in high-resolution marine seismic data using multi-beam echo sounder data, and more particularly, a method for swell effect and mis-tie correction in high-resolution marine seismic data using multi-beam echo sounder data capable of acquiring the high-resolution marine seismic data having the swell effect and the mis-tie effectively corrected by using the multi-beam echo sounder data including water depth data of a sea-bottom having high precision.

1. A method for correcting a swell effect and an mis-tie at the intersection point of marine seismic data using multi-beam echo sounder data measured by a multi-beam sounder, comprising:
a) receiving the multi-beam echo sounder data; b) extracting water depth values corresponding to the same positions(latitude and longitude coordinate points) as shot points at the seismic data in the multi-beam echo sounder data; c) correcting the swell effect and the mis-tie at the coordinate points of the seismic data by reflecting the water depth values; and d) deriving the marine seismic data at which the swell effect and the mis-tie are corrected by performing the steps b and c on all the coordinate points at the seismic data.
