Abstract:

The Sikeshu Sag, located in the west of the Junggar Basin, contains large oil and gas deposits. However, the patterns of source rocks and potentials of hydrocarbon generation in the Jurassic strata are still under debates. Taking into account of TOC, maturity and other organic geochemical indexes, hydrocarbon generation differences from various source rocks are speculated with the carbon isotopes and isopach map. Besides, thermal analysis and numerical modeling were conducted to establish the evolution of source rock and to evaluate the potential exploration prospects in the research area. The results show that the hydrocarbon generated from coal is much better than that of carbonaceous mudstone in the Jurassic strata of Sikeshu Sag. In addition, the gas is transported and gathered mainly in the south of the area. The source rocks in the Sikeshu Sag show high hydrocarbon potentials and explorational values.

Key words: Source rock, Hydrocarbon generation, Sikeshu Sag, Thermal evolutional models, Organic geochemistry
