With the progress of science and technology, the research and development of unconventional oil and gas resources in the world has developed rapidly. In particular, the successful development of shale gas and tight oil in the United States has brought a wide and far-reaching impact on the world. In China, after shale gas,the success of conventional oil and gas in the United States has affected the research and development of tight oil becoming quite active. However, because of the special

... teristics of the tight oil, tight oil has different development methods and reservoir evaluation with traditional petroleum, which increasing difficulty of development. In order to improve economic development, evaluation zone of tight oil reservoir should be appreciated. In this paper, based on the virtual data of the tight oil reservoir zone and that of concentrated zone, which are given by random numbers whose ranges are taken from actual data, and previous studies, we conducted discriminant analysis to evaluate concentration zone of tight oil reservoir in China. The evaluation method is rational and the results based on the virtual data were consistent with the actual tendency. Proposed method is expected to play important role when actual data are accumulated and become available.
