A Study on Reservoir Numerical Simulation Restricted by Fluid Flow Unit

Reservoir numerical simulation plays a very important role in oil production scheme compiling,adjusting and optimizing of production measures,remaining oil study and enhancing oil recovery.The result precision of the reservoir numerical simulation is influenced mainly by the geologic model and the software itself.In order to improve reservoir numerical simulation precision,several methods are used,such as subdividing simulation layers by using fluid flow unit and selecting typical relative permeability curve for different flow units.The result of the simulation indicates that the reservoir numerical simulation restricted by fluid flow unit has many advantages in history matching and precision of remaining oil prediction.
