Application of Coherent Cube and Surface Slice Technologies in Seismic Interpretation in Benbutu Area in Yanqi Basin

Application of coherent cube and surface slice technologies in seismic interpretation can reduce errors resulted from visual correlation and horizon automatic picking, rapidly identifies the overall features of fault system, directly displays the spatial combination of complex fault blocks, and shows interpretation results in 3-D visualized diagrames. These technologies are utilized in fine 3-D seismic interpretation in the Benbutu area in Yanqi basin, leading to much higher processing efficiency and accuracy. Deviation of the predicted target depth from its real drilled depth is below 10m in the appraisal well positioned according to the final research results.
