Abstract: A mathematical model of fluid flow in low permeability gasreservoirs is developed, with gas slippage effect taken into consideration. A numerical solution for the model is provided.Analysis and computation show that the algorithm used has a high level of accuracy and consistency, and thus can serve as a theoretically reliable tool for the study of gas flow in low perme-
ability reservoirs.

Key words: low permeability, gas reservoir, slippage effect, mathematical model, differential equation
