Abstract: Abstract：Zhenwu fault zone is the main oil-bearing structural?belt in Gaoyou sag, where the trap defining is the key factor for oil exploration. The research on fault activity and evolution is the premise for the building of the interpretation model and the improvement of the interpretation accuracy. Based on researches on the regional?tectonic?background, structural style, activity velocities and cross-section balance, the authors ascertained the tectonic characteristics, fault activity and evolution of Zhenwu fault zone, which yielded good application effects, thus providing the geological?basis for accurate structure interpretation and fault?combination.
