| titleOfInvention | A kind of method measuring the optimal miscible pressure of carbon dioxide between injection-production well and mixed phase region |
| abstract | The invention discloses a kind of method measuring the optimal miscible pressure of carbon dioxide between injection-production well and mixed phase region, solve the problem that the minimum miscibility pressure that back-up sand method records does not conforms to the actual conditions.First make carbon dioxide gradually contact under the conditions of different pore throats with crude oil containing natural gas to reach mixed phase and test the minimum miscibility pressure under the conditions of different pore throats, then well is injected to the plane heterogeneity between extraction well according to actual reservoir, test carbon dioxide under the natural core pore throat of different permeabilities for this reservoir and the actual minimum miscibility pressure Pm of crude oil containing natural gas, obtain optimal miscible pressure P of this reservoir.The inventive method can obtain the minimum miscibility pressure of actual heterogeneous reservoir, can simulate actual heterogeneous reservoir and carry out carbon dioxide mixed phase and drive, and draw carbon dioxide mixed phase according to experimental result and drive distribution situation figure, beneficially numerical simulation popularization and application. |
