The low permeability petroleum reservoir, which is controlled by depositional environment, is characterized as low permeability and bad connectivity between sand bodies, associated with big resistance of fluid. The petroleum product pattern for the low permeability reservoir is different with normal permeability reservoir, causing the difficult prediction of petroleum production. In this paper, we introduced 5 predicted production patterns (i.e. double log predict, Weibull, Yuqitai, gray system and fluxionary simulation) to predict the petroleum production in the Gao 5 block. The comparative results suggest that the grey system would have an ability to predict the simple change of petroleum product whereas others provide the complex change. But, there is big error of petroleum product production by using of these five patterns. So we developed a linear pattern of petroleum production prediction that can provide the better prediction of petroleum production.
