The method development of hydrocarbon filling periods is discussed at different study stages. At an early stage, hydrocarbon filling periods and process are derived according to the relationship and efficiency of generation, reservoir, seal, migration, accumulation and preservation. These methods, which are called "forward methods" based on the history of structural evolution, trap evolution and hydrocarbon generation and expulsion, have been developed in more details in recent years. At the same time, hydrocarbon filling periods and process can be "traced" based on fossil records of petroleum migration and accumulation in the reservoirs, such as differentiation of hydrocarbon, fluid inclusions, reservoir bitumen, isotopic dating of authigenic minerals. In the paper, the overall approach of hydrocarbon filling periods and process are displayed by elucidating the filling process of Kela-2, in the base of differentiation of hydrocarbon, fluid inclusions, reservoir bitumen and isotopic dating of authigenic minerals combined with the history of structural evolution, trap evolution, hydrocarbon generation and expulsion and the relationship and efficiency of every geological condition.
