摘　　要：在低渗介质中,流体渗流往往表现出对达西定律的一定偏离。该文对低渗透介质非达西渗流的研究进展进行了总结,内容包括:1)低渗透介质非达西渗流存在的模型;2)低渗非达西渗流是否存在;3)低渗非达西渗流的成因;4)低渗非达西渗流出现的判据;5)低渗非达西渗流的应用。并对其发展提出展望,这些工作可以为从事相关工作的科研、工程应用人员提供参考。The rule for the seepages of fluids in low permeability media deviates Darcy＇s law to some extent. This paper summarizes the research progress on the Non-Darcy seepage in low permeability media. The conclusions include such aspects： first, the models for Non-Darcy seepage in low permeability media;second, whether there is Non-Darcy seepage in low permeability media or not; third, the reason for the formation of Non-Darcy seepage in low permeability media; fourth, the criterions for the appearance of Non-Darcy seepage in low permeability media; Fifth, the applications of Non-Darcy seepage in low permeability media, this paper also gives some advices for the development of Non-Darcy seepage in low permeability media in the future. It could afford some references for the researchers and engineers engaged in related work.
