Abstract The geology on the western edge of the Ordos Basin is complex，and the interpretation of complex underground structures and the prediction results of deep stratigraphic distribution based on existing seismic data are inconsistent with the actual drilling results.To this end，the technical idea of non-seismic interpretation is proposed.In other words，based on conventional non-seismic processing，the specific processing and interpretation focusing on geologic requirements will be reinforced.In view of the strike-slip fault development feature，the enhancement of gravity and magnetic anomaly and body display techniques are used to highlight weak anomalies，and then lighting analysis is carried out in different orientations to extract non-seismic anomalies that can reflect the strike-slip fault.The results can be used to explain the horizontal distribution of the strike-slip fault.In the case of the ‘continuous axis but breaking layer’ phenomenon on the seismic reflection layer，or in other words，the same reflective layer reflects different strata，the time-frequency electromagnetic interpretive processing technology is used to identify the strata attributes after the precise inversion of the target layer，and the result of comprehensive analysis of various information makes the stratigraphic attribution more accurate.For the deep strata where seismic reflective imaging is difficult to realize，gravity–seismic combined stripping can be applied to Lower Paleozoic strata，and the results can be used to predict the deep source rocks of the Changchengian system.
