| Abstract: |
| Based on the structural interpretation and the analysis of 2D/3D seismic data，it is identified that NE-trending/ NEE-trending strike-slip fault zones are distributed in northern slope of Tazhong Uplift, and six identification marks of strike-slip fault in seismic slices and sections are summarized. Three types of strike-slip fault system which superimposed in space are developed, including compresso-shear faults(end of Middle Ordovician to Silurian)，tenso-shear faults (Late Devonian to Early Carboniferous) and thrust faults(Late Permian). It is concluded that the development of fractured reservoir and fractured-vuggy reservoir was controled by the intensity of fault deformation,and the development of high-quality fractured-vuggy reservoir was dominated by the segmentation of strike-slip faults. It is suggested that the fracture zones with strong deformation, the pull-apart structure， and the trough fault zone where superimposed reformation by later faults and with beading seismic anomalies are favorable targets for exploring large-scale natural gas reservoir of Ordovician. |
