摘　　要：在调研有关低渗透渗流影响因素的基础上,对影响低渗气藏渗流的主要因素进行了归纳与总结。结果表明影响低渗气藏的主要因素有应力作用、启动压力梯度、渗透率、滑脱效应、水锁效应等。并在此基础上分析了造成这些主要影响因素的原因。这些因素对低渗气藏渗流影响各有不同,但最终均引起低渗气藏渗流的非线性化。Based on the investigation and study for percolation influencing factors of low permeability, main factors affecting percolation of low permeability gas reservoir are concluded and summarized. It is indicated that the main factors affecting low permeability gas reservoir are stress action, start - up pressure gradient, permeability, slippage effect, and water blocking effect etc.. Based on the results, the causes of the main influencing factors are analyzed. These factors have different effects on percolation of low permeability gas reservoir, but finally lead to percolation nonlinear for low permeability gas reservoir.
