摘要

摘要: 致密砂岩气藏储层岩石孔隙结构复杂,孔喉细小,气体渗流特征有别于常规气藏。采用逐级增压气驱实验和定容衰竭开采物理模拟实验相结合的方法,测试分析了气体在砂岩储层岩心中的渗流特征。研究表明:气体在致密砂岩储层岩心中有效流动的条件是需要有足够大的流动压差克服沿程摩阻,这也是致密气藏储量得到动用的门槛条件。气相渗流特征受岩心基质渗透率、含水饱和度、岩心长度、上覆压力等多种因素的影响,在致密气藏开发过程中,需要综合考虑这些因素对气井产能及稳产能力的影响。

Abstract: Properties of gas flow in tight gas reservoirs are different from those in conventional gas reservoirs due to complex pore structure and tiny pore throat. Gas drive experiment by increasing pressure progressively and constant depletion physical simulation experiment were used in this paper so as to analyze gas flow characteristics in sandstone reservoir cores. The results indicated that, flow pressure difference enough big was required to overcome friction. This is the threshold for tight gas reservoir development. Gas flow properties are influenced by many factors such as basis permeability, water saturation, core length and overburden pressure. They may influence gas well productivity and rate maintenance capability and should be paid attention to before tight gas reservoir development.
