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,从而为准确确定非达西系数数学表达式奠定了基础。

关键词: 低渗气藏, 非达西渗流, 滑脱现象, 克林肯贝尔效应

Abstract: 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 nonDarcy 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.

Key words: low permeability gas reservoir, non-darcy flow, slippage phenomena, Klinkenberg effect
