By numerical simulation method Blocklis taken for example to evaluate the well pattern infilling effect in the process of waterfooding at the low permeability oilfield to give a reasonable injection-production ratio and to improve correlations between the corresponding injection and production. After well pattern infilling, along with the injection-production ratio increases, the composite development effects change from a good to bad with he best injection-production ratio of 2.5. The effective driving pressure system could be built-up after well infilling measures which can overcome the difficulties caused by low permeability and can increase producing level of the geological reserve effectually. The results of the study will be useful to guide the next adjustment of oilfields and the scientific development of similar oilfields.
