Abstract:Different sections in a 2-D seismic grid may be obtained under different condidons of data acquisition and data processing,so that time and waveforrn differences often occur between the same seismic horizons in two intersecting sections.Consequently,troubles arise in data interpretation arid further data processing,such as 2-D seismic data being interpolated into 3-D seismic data.A method for interactive mis-tie correction is put forward to cope with different properties of different seismic lines.In the method,correction operators of different lines are simultaneously computed to make time-depedent and space-depedent corrections of rnis-ties and waveforms at intersecting points of corresponding seismic horizons.The mis-tie distributions can be displayed at any time you want.The interactive process is easy and nimble.The final mis-tie accuracy satisfies the requirement of seismic interpretation mapping.
