Abstract: Xingliudong Block, having been developed for more than 40 years, finished its third infilling in 2007. Aiming at the problems of excessive layers, interlayer heterogeneity and great discrepancy of each layer’s producing extent, the waterflooding experiment of different permeability contrast combinations was carried out. Combining the adjustment research of layer series and well pattern, this reservoir is divided into three layer series which have a permeability contrast less than 6. Three corresponding well patterns are designed, which are significantfor the development of oil layers, especially the poor layers. With the numerical simulation technology, the best scheme is selected. According to the results, scheme 2, raising the oil recovery to 49.18%, is the best solution.
