摘要(Abstract):

通过实验手段 ,探索了特低渗透率岩心单相流体渗流特征。通过毛管束模型描述了流体边界层厚度随压力梯度的变化规律 ,由此建立了描述低渗透油层非达西渗流特征的经验方程。
This paper discusses the seepage flow characteristic of the single phase fluid in ultra low permeable cores using experimental method It describes the rule of fluid boundary layer thickness changing with pressure gradient using the model of bundles of capillary tubes and then constructs an empirical equation which illustrates the non Darcy seepage flow characteristic of ultra low permeable reservoirs
