The oil reservoir chemical engineering has been developed in the cross fields of the related disciplines of oil reservoir engineering and chemistry based on the tertiary oil recovery. It is a discipline of the study of the transport phenomenon and chemical reactions happened in the oil reservoir environment，the principles and regulations affecting the dynamics of the oil reservoir. The applications of a series of new methods，thoughts and theories of chemical engineering will play an important driving role in the formation of oil reservoir chemical engineering. Meanwhile，the develompent of chemical engineering，combined with the unique natural resources and the social economics in China will promote oil reservoir chemical engineering more and more. The complicated environment and the rich content of the discipline of oil reservoir chemical engineering provide a wide range to the development of the frontiers of chemical engineering. Some relative works still need to be strengthened in China are proposed.
