Many problems must be solved such as partial non-perfect injection-production, low degree of reserve control, under - injection in water wells and too many shutdown wells in Es4. Based on 3 -D seismic data with high precision of this block, some additional wells were drilled in the area with abundant remaining oil, and then the producing degree of reserves was increased. Converting some oil wells to injection wells pertinently enhanced ratio of injection-production correspondence. Through the research on plugging mechanism of oil -and -water well, the acidizing fluid formula and acidization technology were optimized. The effect of augmented injection capacity in water wells and broken down in oil wells is obvious. Raising liquid production after the production pressure differential was magnified in optimized partial oil wells, the productivity was improved. After a series of integrated adjusting measures were carried out, cumulative incremental oil production was 7.0×104t in three years, and the calibrated recovery efficiency was improved 3% .</em></p><p
