Abstract: The upper Karamay Formation in eastern block Wu 2, Karamay Oilfield, is sandy conglomerate reservoir of fan delta, which is characterized by complex sand body distribution, strong heterogeneity and poor effect of water injection and oil production. The data of core, laboratory analysis and well logging were used to study the heterogeneity of reservoir distribution and quality. The data of practical production and the results of qualitative analysis, fine quantitative characterization and synthesis evaluation obtained by entropy method, were adopted to analyze the effects of the distribution and quality heterogeneity on the performance of actual development measure. The result shows that the inter-layer heterogeneity is generally medium. The permeability of layer is dominated by positive rhythm, compound positive rhythm and homogeneous rhythm, and the reservoir quality heterogeneity is strong. In the same sand-body controlled by facies constraints, the reservoir quality heterogeneity is medium to strong. Vertically, the S5 and S1 sand layers are consist of medium-thick sand bodies and can be divided into many layers, with other layers showing isolated single sand body form. The sand body distribution on the plane is controlled by sedimentary microfacies. The heterogeneity of reservoir distribution leads to inefficiency of injection and production. The heterogeneity of reservoir quality leads to poor effect of injection production. This conclusion is of great significance for adjusting the injection production well pattern and measures.

Key words: remaining oil distribution, numerical simulation, interlayer, reservoir architecture, Bohai Sea
