Studies of 3D Reservoir Modeling: Taking Ordovician Carbonate Fractured-Vuggy Reservoirs in Tahe Oil Field as an Example
详细信息   
摘要
Carbonate fractured-vuggy reservoirs are basically different from clastic or other fracture-pore reservoirs.Karst caves,fractures and corroded pores coexist in the carbonate fractured-vuggy reservoirs and challenge traditional clastic reservoir modeling theories and methods.A modeling technique based on fractured-vuggy unit has been proposed.It is featured by “5 steps” including the establishments of 5 models: cave distribution,fracture discrete distribution,cave petrophysical parameter,fracture parameter as well as fracture and cave connection.The model illustrates the 3D distribution and features of fractured-vuggy reservoirs and provides theoretical basement for reservoir exploration.
