Concentrated zones assessment of tight oil reservoir
Liu (2018) described the concentrated zone evaluation of the tight oil reservoir in " Concentrated zones assessment of tight oil reservoir on discriminant analysis in China".
With the progress of science and technology, the research and development of unconventional oil and gas resources in the world have 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 characteristics of tight oil, tight oil has different development methods and reservoir evaluation with traditional petroleum, which increases the difficulty of development. To improve economic development, the evaluation zone of tight oil reservoirs should be appreciated. In this paper, based on the virtual data of the tight oil reservoir zone and that of the concentrated zone, which is given by random numbers whose ranges are taken from actual data, and previous studies, we conducted a discriminant analysis to evaluate the concentration zone of the tight oil reservoir in China. The evaluation method is rational and the results based on the virtual data were consistent with the actual tendency. The proposed method is expected to play an important role when actual data are accumulated and become available.
