With the advancement of tight oil resource exploration and development， the research of the porosity and permeability cutoffs for tight sandstone reservoir becomes important, which can be used to predict favorable areas for exploration. Based on the study of other’s work, the determination method for the porosity and permeability cutoffs can be divided into three categories， (1)Positive method， to calculate the porosity and permeability cutoffs through various experiments on cores， including capillary pressure analysis， the simulation of filling， the irreducible water saturation， minimum flow pore throat radius and the adsorption of water film thickness;(2) Reverse method，to calculate porosity and permeability cutoffs according to actual production data， including oil testing data statistics， φ-K crossplot， oil bearing condition of the tight sandstone， the distribution function curve method;(3) Comprehensive study method， to calculate the porosity and permeability cutoffs with combined methods. Through the comparison of the three methods, it is found that the results of positive study are less than that of reverse method, however, the process is complicated relatively. And the reverse method is limited by current economic and technical conditions and the results are larger than the positive method with greater significance to guide production. Thus, integrated application shall be conducted to identify the porosity and permeability cutoffs.
