摘要
低渗透气田在我国分布极广，开发此类气田具有重要的现实意义。在考虑低渗透气藏气体渗流的滑脱效应下，建立了低渗透气藏气体渗流数学模型，提出了一种数值求解方法。通过分析与计算，结果表明：该算法具有高精度、稳定性好、适应性强等特点，为低渗透气体渗流研究提供了理论依据。
A mathematical
model of fluid flow in low permeability gas reservoirs 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 permeability reservoirs.
