摘要：

尽管经典渗流力学提出了达西定律存在适用的速度下限，但是没有明确低速状态下非达西渗流规律。选取了四川盆地须家河组7组致密砂岩气样品进行渗流物理模拟实验，每个样品测定10~15个渗流数据点，最高注气压力为10MPa，并始终保持环压高于注入压力2~3MPa，以确保气体是沿致密砂岩孔隙流动而不会沿着岩心与加持器内壁发生串流。实验模拟了气体在致密砂岩中的完整运移过程，有效探索了致密气渗流机制，提出致密砂岩气渗流具备极低速非线性渗流、低速非线性渗流和低速线性渗流3个阶段，以及具备复合型、下凹型、上凸型和直线型4种渗流曲线模式的新认识。

Abstract:

Although the Darcy′s law with applicable speed limit was proposed in classical percolation mechanics,the non-Darcy percolation law is not clear under the low speed condition.7 groups of seepage simulation experiments of the Xujiahe tight gas reservoir in the Sichuan Basin were carried out with highest gas injection pressure of 10MPa and confining pressure higher than the injection pressure of 2-3MPa in order to ensure that the gas migrated along the tight sandstone rather than along the inner wall of the core and blessings.10-15 flow data points were determined in each experiment.The experiments of the complete process of gas migration in tight sandstone effectively explore the tight gas seepage mechanism.Results of the experiments indicate that the seepage process of tight gas has 3 stages (very low-velocity & non-linear stage,low-velocity & non-linear seepage,low-velocity & linear stage),and 4 seepage curve models (composite type,concave type,convex type,linear type).

Key words: Sichuan Basin, Tight gas sands, Physical simulation experiment, Seepage mechanism
