Limited by lateral seismic resolution and the quality of migration imaging, the structure interpretation of high-angle strata directly affected the follow-up research of the structure, deposition and reservoir evaluation. In this paper, the HZ25-7 stratigraphic trap in the Huizhou Depression of eastern Pearl River Mouth Basin was used as an example to study the improvement of lateral seismic resolution through theoretical derivation, forward modeling, re-processing and re-acquisition of 3D seismic data. Based on the research, interpretations of paleogeomorphogloic map, combined with the geological background and drilled wells, were used to analyze the deposition system and reservoir in this area.
