Application of graph theoretic model to design of reservoir simulation software based on grid

The selection of the oil well models has a direct effect on the whole calculation results in the simulation of reservoir. A new type of oil well model in accordance with the law of seepage was constructed in full consideration of seepage features nearby the oil well. The graph theory, which is a main tool for the network analysis, was applied to the design of the reservoir simulation software, in order to realize the management of grid with the complex configuration. The completion of the reservoir simulation software using the IMPES and Full-Implication methods is on the grid management system. The simulation result of a simple example shows that the reservoir simulation software designed with the new oil well model can describe the changes of the flow pressure at the bottom hole better than the traditional simulation software.
