%X By the technique of CT scanned image,the micro-structure,the distribution of water saturation,water absorbing capacity and the effect on oil-displacement efficiency by the micro-pore structure were studied dynamically,quantitatively,visually.The research shows that the distribution of CT value is from 1819 to 1961,which is 15% above that of the Berea sandstone.It belongs to the representative ultra-low permeability sandstone reservoir.The micro-pore structure is the essential factor for the distribution of oil and water.The water free recovery factor should be emphasized in the development of the ultra-low permeability sandstone reservoir.The compact texture and the discrepancy of the micro-fracture are the primary reasons for the low efficieney of oil displacement.
