METHOD FOR SWELL EFFECT CORRECTION OF MULTICHANNEL 3D STRATUM SURVEY DATA AND MARINE 3D SEISMIC SURVEY METHOD USING SAME

摘要

The present invention relates to a data processing method for correcting a swell effect from seismic survey data acquired from a marine 3D seismic survey. As a transmission time of a sound wave is affected by a change in a height between a sound source and a receiver in accordance with a swell in an actual marine survey, a water level of a survey area is measured on the basis of a sea level. Moreover, after a theoretical arrival time (standard arrival time) of a sea-bed reflection signal is calculated, difference between the standard arrival time and an actual arrival time is used to remove a swell effect of seismic survey data.;COPYRIGHT KIPO 2019
