Dalu Lake is a low permeability reservoir.Now it is during the middle period and later period of oil development. To enhance oil recovery.Numerical simulation has been implied into the paper.By means of the theory,the production of various sand reservoirs have been analised here. Based on the problems of various sand reservoirs, EOR including perfection well pattern?decreasing wells ?unsteady injection have been discussed here.Recovery percent of reserves of Ⅳ sand group is the best than the others.
