It is the main fault controlling the basins of Dongpu depression and Linqing sag.

In present structural unit classification scheme, Dongpu Depression belongs to Linqing Sag as a third class negative element in the southmost of Bohai Gulf Basin.

The Study on Tectonic Evolution History of Western Depression Belt in Bayanhot Basin;

Gas exploration has achieved a great success in the western depression of Sichuan Basin, but difficulty of exploration and development also has been increasing.

The deposita of shallow marine-littoral, lacustrine and fluvial facies of Upper Triassic in west Sichuan depression occur with abundant oil-gas resources, which form a petroleum system dominated by natural gas.

Based on new theories and methods of petroleum system and organicgeochemistry, the author studied and discussed hydrocarbon-source rock of lowerTertiary in Yucheng area in several aspects, such as sedimentary organic facies,abundant of organic matter, organic type, maturity, reservoir property, andclassification of oil-gas system and their characteristics.
