Abstract
Interlayer is one of the major factors which results in the heterogeneity of reservoir, and it is the important content of reservoir fine characterization. In this paper, taking WZ oilfield as an example, the object-based simulation method is used to characterize the spatial distribution regularity of calcareous intercalation and sand-stone, design the experiment scheme through the orthogonal experiment design method and analysis the factors that influence the distribution of interlayer. Results showed that the object-based simulation method can characterize the shape of calcareous intercalation very well, and the orthogonal experiment design can distinguish the influence of various factors.
