| Zusammenfassung: | The invention discloses a flow simulation and transient well analysis method based on generalized pipe flow seepage coupling. The flow simulation and transient well analysis method comprises the following steps of S1, introducing generalized fluidity, and establishing a fluid motion equation of generalized pipe flow-seepage coupling; S2, substituting the established fluid motion equation into a mass conservation equation, and establishing a corresponding reservoir control equation according to the specific shape of the reservoir; S3, establishing different flow simulation and transient well analysis models according to a pipe flow and seepage coupling system formed by the combination relation of different structural reservoirs and the combination relation of different wells and different reservoirs; and S4, forming corresponding application software by using the established different flow simulation and transient well analysis models. The method plays an important role in solving the problems of flow simulati |
