Abstract: Taking the deep-water channel reservoir of Niger delta in West Africa as example, this study shows how the multi-parameter technology was applied to discriminate different flow units in deep-water turbidity channel reservoir. By selecting mud content, porosity and permeability for considering parameters and by cluster analysis, we divided four kinds of flow units (A, B, C, D) of the deep-water turbidity channel reservoir in the Neger delta. Meanwhile, we established the model of flow units in the method of cluster analysis. Based on the model analysis, we interpreted the flow units in the single well and discussed their spatial distribution of flow units. Our study shows that the reservoir quality of flow units (A and B) distributing in the middle of channels are the best. The distribution characters of flow units in single channel may be different due to different development of deep-water turbidity channel.
