3D reservoir geologic modeling and potential tapping in glutenite reservoir: A case study from conglomerate reservoirs in Karamay Oilfield

The heterogeneity of conglomerate reservoir is studied by 3D geologic modeling.The main potential tapping and potential zone are illustrated.The 3D geologic modeling includes reservoir structure modeling,sedimentary microfacies modeling and reservoir parameter modeling.The structure modeling achieves the intercalibration process of fault-point data and individual layer data derived from seismic interpretation and drilling.Sedimentary microfacies modeling displays the reservoir volume,geometric shape and 3D distribution.Reservoir parameter modeling carries out the reservoir parameter model constrained by facies belt distribution range,original reservoir data and 3D geologic interpretation.The result shows that the modeling overcomes the disadvantage caused by various data with different resolution,optimizes the geologic modeling for heterogeneity conglomerate reservoir suitable for practical production,and indicates the potential zone and reservoir range controlled by favorable sedimentary facies belt.
