For a great number of sandstone reservoirs with low porosity and permeability, it is more difficult to implement a quantitative evaluation because of various influencing factors. However, a multiple-parameter weight quantitative method is just to have a match between each parameter and production rate during a well testing at first, and then to choose many evaluation parameters according to their correlation, thirdly to determine a weight coefficient among parameters in order to make the primary and secondary relations clear, and finally to finish a quantitative evaluation on these sandstone reservoirs. In this study, the Shihezi₈ Member in Sulige gasfield, a low-porosity and low-permeability sandstone reservoir, is taken as an example. Five quantitative parameters （containing effective thickness, porosity, gas saturation, thickness, and permeability）and two qualitative parameters （including sedimentary facies and diagenetic facies）are selected as evaluation parameters. And, this method has been applied to reservoir evaluation. Results show that both I- and II-type stacked favorable belts have an area of 2687.2 km²; a higher drilling success ratio can be gained for the optimized favorable belts; and the drilling rate reaches 94.3 %. All results further prove that this method is reasonable and practical.
