Research on Coupled Flow in Deformation Medium Reservoir with Cave

Abstract:

For the geological features of deformation medium reservoir containing cave, both Darcy seepage process in deformation medium reservoir and Navier-Stokes free flow process in cave are considered. Researching seepage flow in reservoir and free flow in cave as a whole through coupled conditions on the interface, the mathematical model of the coupled flow in the deformation medium reservoir with cave is established. For the flow characteristic of Darcy seepage and Navier-Stokes free flow, the coupling simulation is completed through balance condition of flux and pressure on the interface. The numerical solution is gained, and the chart of pressure and saturation distribution is drawn. The dynamic variation of pressure and saturation is discussed, which could describe dynamic characteristics of the coupled flow in the deformation medium reservoir with cave.
