Microscopic pore structure in different types of lithofacies units of fan delta reservoir in the first member of Kongdian Group was characterized by photo lithography model and image analysis system in a block of Kongnan area, Dagang Oilfield. The distribution modes of micro-remaining oil in different types of lithofacies units during the waterflood test were analyzed quantitatively and qualitatively, thus the controlling factors for remaining oil distribution were discussed. The results show that the distribution shapes of micro-remaining oil in fan delta reservoir mainly include island remaining oil by blocking in the disconnected pore, accounting for about 75% of all remaining oil, flake remaining oil by interrupting in the small pore and throat, about 20% of all remaining oil, and the beadlike and membranous remaining oil, less than 5% of all remaining oil.oft-com:office:office" />
