Improvement of the Method for Predicting Minimum Miscible Pressure |
| |
Abstract: | The method for predicting minimum miscible pressure by equation of state is introduced. And by means of slim-tube test results and the concept of "miscible function", the method is improved. The improved method overcomes the shortcoming of the original method that the critical value of plus fraction is difficult to determine, and it also improves the sensitivity of the calculated minimum miscible pressure to temperature. The validity of the improved method is proven by the results of some examples. |
