| The Reverse Structural Styles in the Shiwu Rift Depression, Songliao Basin, and Their Oil and Gas Exploration Significance |
| Four reverse structural zones in Shiwu rift depression were determined and their structural styles were described on the basis of interpreting typical profiles by using 3-D high resolution seismic data. The Gujiazi-Houwujiahu reverse structural zone is characterized by tyrannous faults, whereas the Xiaowujiazi-Sijiazi reverse structural zone shows a box-like anticline in shallow place and tyrannous reverse faults in depth. The Qinjiatun reverse structural zone is a tine ridge anticline developed above the early half-graben. The Pijia-Maobe-Zhangjiatun reverse structural zone assumes a small anticline or syncline. As important hydrocarbon traps, these reverse structural zones are usually distributed near the deep source depression and have favorable petroleum geological conditions. |
