中文摘要: 致密岩石介质中的气体渗流有别于液体渗流,其中滑脱效应是影响致密岩石介质中气体渗流规律的一个重要因素。通过分析国内外学者在气体滑脱效应方面的研究进展,总结了滑脱效应的产生机理和产生条件,认为气体分子在孔壁附近的运动状态是产生滑脱效应的根本原因。同时围绕孔隙气体压力、围压、含水饱和度、气体性质等因素对气体滑脱效应的影响及实质进行综合分析。分析结果对研究低渗透多孔介质中气体渗流规律和测定低渗气田开发中气体渗透率参数等方面具有较大的参考意义。
Abstract:The gas seepage in compact rock media is different from fluid seepage. The gas slippage effect is an important factor affecting gas flow in compact porous media. This paper summarizes the research progress on the gas slippage effect and synthetically analyzes the production mechanism and conditions of slippage effect, considering that the motion state of gas molecules near the pore wall contributes to the slippage effect of the gas. In addition, the effect of pore gas pressure, confining pressure, water saturation, gas properties, and other factors on the effect of gas slippage and its essence are studied and analyzed. It is of great reference for studying gas flow law in low permeability medium and measuring the gas permeability parameters in the development of low-permeability gas fields,etc.
