| Abstract: | A discreted model for well completions was developed with the finite- element method. Some numerically simulated results are obtained. The effects of perforation length. damage zone. crushed zone, perforation diameter and phase angle on productivity ratio and skin coefficient are analyzed. This discreted model and numerical method have small errors and can save a lot of computation time. |
