摘要
Chang-2 formation of Xiasiwan area is a major petroleum reservoir.Using the homogeneous temperature of inclusion and with regards to the burial history of formation and the thermal evolution history of Ordos Basin,a study on fluid inclusions was done systematicaly in order to determine the period of hydrocarbon accumulation in Xiasiwan area. It was ultimately determined that the time of hydrocarbon accumulation was of one phase in this area,and the age of accumulation was between 110 Ma and 125 Ma,which is nearly the late Early cretaceous.
