报告内容摘要：

Secondary oil recovery led by water flood accounts for one half of the oil recovered in the United States. Furthermore, streamline simulation is becoming more and more popular these days due to its higher speed compared with finite-difference method. In this project, a streamline simulator is developed for water flood and gas injection. Oil recovery and water cut from the streamline simulator are compared with their counterparts from a finite-difference simulator. In addition, a practical method to implement an extremely large time step in streamline simulation is introduced. Results show that numerical dispersions decrease from finite difference method, to numerical streamline method, and to analytical streamline method. For numerical method, numerical dispersions decrease with increased time step size. By using the practical method, streamline simulations have greatly been sped up.
