Abstract EN
Field evidence indicates that cavities often occur in fractured rocks, especially in a Karst region.
Once the immiscible liquid flows into the cavity, the cavity has the immiscible liquid entrapped and results in a low recovery ratio.
In this paper, the immiscible liquid transport in cavity-fractures was simulated by Lattice Boltzmann Method (LBM).
The interfacial and surface tensions were incorporated by Multicomponent Shan-Chen (MCSC) model.
Three various fracture positions were generated to investigate the influence on the irreducible nonwetting phase saturation and displacement time.
The influences of fracture aperture and wettability on the immiscible liquid transport were discussed and analyzed.
It was found that the cavity resulted in a long displacement time.
Increasing the fracture aperture with the corresponding decrease in displacement pressure led to the long displacement time.
This consequently decreased the irreducible nonwetting phase saturation.
The fracture positions had a significant effect on the displacement time and irreducible saturation.
The distribution of the irreducible nonwetting phase was strongly dependent on wettability and fracture position.
Furthermore, this study demonstrated that the LBM was very effective in simulating the immiscible two-phase flow in the cavity-fracture.
