摘　　要：通过室内物理模拟气体驱替岩芯实验和对实验数据的分析 ,验证了气体在低渗气藏中的渗流存在滑脱现象 ,即克林肯贝尔效应 ,遵循非达西渗流规律 ;并对低渗气藏非达西渗流现象的影响因素做了定性分析 。Gas slippage phenomena existing gas flow in low permeability gas reservoir was verified through indoor physical simulation experiment of gas displacing core and analysis of the experimental data, which is the Kinkenberg effect subjected to non-Darcy seepage flow low. At the same time,factors that influenced gas Non-Darcy flow in tight gas reservoir were analyzed,and this established the stable foundation for well and truly confirming the mathematic expression of Non-Darcy factor.
