Abstract：Enhancing oil recovery by study of remaining oil distribution is the subject of oil-field development in east region,the fine reservoir modeling study on the basis of fine geologic model-building is key tool of effectively determining the abundance zone of remaining oil in the reservoir.The main oil-fields of Shengli oil-region have come into high watercut period successively,the reservoir has been waterflooded in large scale and the waterflooded area and volume have been further enlarged,so looking for remaining oil and enhancing recovery become the key and difficult points in development of oilfield and are also the key of stable production at the same time.On the basis of summing up former 5 rounds of fine reservoir simulation in Shengli oilfield,the paper try to systematically analyze and study the fine reservoir simulation.Starting from geologic model-building technique assuring the simulation precision, the paper analyzed relevant techniques that have a impact on precision of struc-tural model and reservoir model,hopping to guide geologic model-building of reservoir and study of reservoir simulation for other oilfield in the later stage of development.
