| Abstract: |
| Abundant CO2 and N2 gas reservoirs and other N2-bearing gas reservoirs are discovered in the Neogene and Quarternary shallow beds of Central Mud diapir Zone in Yinggehai Basin, South China Sea during recent 20 years’oil and gas exploration. According to geological and geochemical characteristics of N2, the N2 gas in this area can be divided into three types in genesis, i.e. the atmosphere genesis, the crust organic genesis and the crust-derived organic-inorganic-mixed genesis. Combined with results from the nitrogen-producing experiments under T- and P-controlled thermal simulation and the characteristics of partial enrichment in plane and layering and zoning enrichment in vertical, it is |
