Abstract: From viewpoint of systematology and complexity theory, the petroleum system is an open complex dynamic one. The system is characterized by the overall function greater than the sum of partial functions, diversity and indeterminacy of its physical makeup, diversity of structure and reservoir types, diversity and relevancy of reservoir formation processes, special stages, non-linearity and dynamics of its evolution, and the multiple disciplines involved in it. It is also an open and dissipative system and has the features of self-organization and orderliness of hydrocarbon distribution. The study of complex system calls for new methodology. The integrated modeling method, which combines the scientific theory,expert system and computation technology as a whole,is an important way to understand the complexity of petroleum system. Its scientific thinking embodies the four unities of opposites including qualitative and quantitative, static and dynamic, reductionism and holism, deterrninacy and randomness. Five development trends of the modeling technique for petroleum system are described in this paper.
