%X Only the traps developed before or at the same time of hydrocarbon migration could be charged by hydrocarbons and formed reservoirs.To determine the time and space domains of hydrocarbon migration and accumulation in the Ordovician carbonates of the Huanghua depression in the Bohaiwan basin,China,the homogenization temperature of the fluid inclusions and K/Ar isotopic ages of the autogenous illites were measured,and the structural developing history,the thermal history,hydrocarbon generation history and migration history of the depression were analyzed.Then the mathematical statistics of hydrocarbon migration times corresponding to the homogenization temperature of the fluid inclusions in the different stages of all the samples was carried out to avoid the uncertainty of the migration times.As the results show,the hydrocarbon migration and accumulation in the Huanghua depression took place in Indosinian epoch,Yanshan epoch and Himalayan epoch.The distribution areas of organic fluid inclusions showed the areas of the hydrocarbon migration and accumulation.The hydrocarbon migration area in the Indosinian epoch (T_3) was in the southwestern Huanghua depression,then expanded to the eastern boundary of the depression during the Yanshan epoch (K_1-K_2),and finally reached the northern Huanghua depression in the Himalayan epoch (E_2-N_1).The petroleum exploration of the Ordovieian carbonates should have been focused on the traps in the southwestern Huanghua depression that formed in the Indosinian epoch and haven't been destroyed by later structural movements.
