lnfill well location optimizing method in Sapu oil reservoirs of Daqing peripheral oilfields

In viewpoint of the following problems in Sapu oil layers of peripheral oilfields:scattered distribution of sand body,low control degree of water flooding under the condition of current well pattern and stray residual oil distribution in the medium and late stages of development and so on,on the basis of the studies of different pattern' s residual oil distribution type and reasonable infill mode,the paper deeply studies well location optimizing method on the basis of the results of fine oil reservoir characterization and taking adjustable thickness as infill limit and furthermore taking the produced degree and water cut of adjacent producers as parameters.The set of methods can guide the infill adjustment of Sapu oil layers with medium and high water cut of Daqing peripheral oilfields and increases the infill effects and economic benefits of these oilfields.
