Abstract:Trace interpolation technique can change 2-D grid data into 3-D seismic data suitable for migration,it also can be used in 3-D seismic exploration.In 3-D seismic exploration,first, field layout is designed in accordance with the requirement that there are at least three sampling points in the width of a smallest fault block which must be ascertwined;then,data acquisition is madet finally,in data processing,the field seismic data are interpolated according to required line spacing and CDP spacing.The paper describes the trace interpolation technique and gives the example of trace interpolation of 3-D seismic data in Wennan area,Dongpu depression.It has been proved that both the S/N ratio and the resolutian of interpolated seismic data show obvious improvement.
