The main reservoirs of Triassic in H area of Ordos Basin are Chang 6, Chang 4+5 and Chang 2, which are typical low-permeability reservoirs. In order to obtain the regulations of flowing liquid and the characteristics of two phase flow, the water/oil displacement experiment inHarea is carried out by real sandstonemodel. Thin section analysis, physical property, scanning electronic microscope, relative permeability andmercury penetration are applied to analyze the influencing factors for the displacement efficiency in this area, which include pore structure, displacement pressure andwettability. Physical propertyhas little effect onthe displacement efficiency.
