    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.
