Facies-controlled Modeling and Reserve Calculation of Petrophysical Facies for Fuyu Oil Reservoir in the North of Honggang

Fuyu oil reservoirin the north of Honggang is a lithologic reservoir,which is a typical ultra-low porosity and low permeability reservoir with the complex geological features,large variable lithology,and very poor reservoir properties,and the remaining unused reservoir is hard to further implement.Petrophysical facies can better reflect the genetic characteristics of reservoir properties,especially the capacity differences of different petrophysical facies,the research results of petrophysical facies can guide the reservoir evaluation and provide scientific basis of the measures for oil field development and scientific management of reservoir.Using sequential indicator simulation method stimulates lithofacies,and builds property model controlled by lithofacies.It can calculate reserves by using the volume model in Petrel.Because of taking full account of the reservoir heterogeneity, it greatly increases the computational accuracy.
