Abstract: The steady-state flow mathematical model for anisotropic reservoir with impermeable barrier is developed. The pressure equation of arbitrary point of formation is obtained by using boundary element method (BEM) to the model solution, and streamline field generating technique is then proposed, including the streamline distribution diagram with anisotropic flow field, complex boundary and impermeable area effects as well as streamline feature analysis. The study shows that the streamline distribution is sensitive to the existing anisotropic flow field and impermeable area. Hence, the plotted diagram could more visually reflect the flowing tracks of reservoir fluid between injector and producer, providing an important basis for optimization of well pattern and injection strategy.
