Abstract: The lateral heterogeneity of an oil reservoir is one of important factors affecting its waterflood response. Based on the time and characteristic of response and water breakthrough in an oil well following waterflood, the heterogeneous coefficients between two wells can be calculated, by which the mass production is optimized, allowing oil wells with different well spacing and core intersection in a well group to realize the minimum affect from such a lateral heterogeneity to the reservoir. This method has been applied to BZ25-1S field in performance management and the obvious effectiveness has been achieved.

Key words: water drive, heterogeneity, reservoir, optimization
