摘要
Based on the studies on the faults system in the central part of Junggar Basin such as the 2D and 3D seismic faults structural style interpretation, deep and shallow layer fault growth index, fault activity rate calculation, and maximum principle stress test in various tectonic events analyzed from acoustic emission data, as well as study on the regional structural evolution and hydrocarbon migration and accumulation, the faults system formation, evolution, basic characteristics and hydrocarbon-controlling model are studied through experiments. The results show that central part of Junggar Basin experienced compression and strike-slip resulted from collision by Peripheral plates, leading to well-developed faults. This experiment result proves to be correct by the fluid geochemical analytical data of both sides of the fault, which is significant for understanding the oil migration and accumulation in the fault system in the central part of Junggar Basin, and is useful for guiding oil exploration and development.
