Abstract
Through natural partition and clustering analysis, four kinds of flow units were distinguished in Pu53 block, Pucheng Oilfield. Taking the short-term cycle as studying unit, the two-dimensional distribution of each type of flow units was forecasted and the short-term cycle was classified into four types based on the two-dimensional characteristics of the flow units. The remaining oil was predicted by conceptual simulation, qualitative analysis and quantitative modeling. The results showed obvious control of the characteristics of reservoir flow units to the remaining oil. E and G units in type I and type II short-term cycles which are distributed continuously in large areas are mostly flooded, while the uncontrolled small isolated G flow unit in type III short-term cycles which were mainly made of F flow unit and F flow unit with continuous distribution become the accumulating place for remaining oil. Thus the development adjustment strategy should optimize the development of small-scale E and G units, strengthen the development of type III short-term cycles, and block out type I short-term cycles. This strategy improves the development of Pu53 block obviously.
