Fracture Prediction Method and Its Application in Wubei Area of Hailar Basin

Based on 3D seismic data, the tectonic stress field in Wubei area of Hailar basin is simulated on the basis of establishing sequence framework and fine fault interpretation. The distribution of structural fractures is predicted by structural curvature, maximum principal strain, maximum principal stress and other parameters. The results show that there is a good correlation between the distribution of structural stress field and the structural fault system. The fracture development zone is distributed at the intersection of two groups of faults in different directions, near the hanging wall of normal fault or reverse fault. The influence factors of fracture prediction are mainly the accuracy of fault location and direction, and the large changes of horizontal thickness and density of the stratum also affect the prediction accuracy.
