| | Abstract | | The amount of oil production in the world is decreasing recently and it is of importance to seek the technological development for enhancing the recovery of oil in place in the subsurface:Enhanced oil recovery(EOR). Seismic stimulation is known as one of the methods of EOR. Recently, many laboratory experiments and field tests have been performed such as water, gas, chemical, or thermal injections to attempt the enhancement of oil production. Numerous observations show that seismic stimulation of oil reservoir may alter water and oil production. We attempt to understand the mechanism of the flux increment in viscous laminar flow under oscillating boundary condition to simulate seismic EOR. We use Lattice Boltzmann method (LBM), one of the computational fluid dynamics methods. And we found the possibility of flux change by the oscillated boundary wall because of partial high pressure gradient and flow velocity difference. In this time, we start to analyze a single-phase flow in the combination of various pore shapes and scales with 2D LBM scheme. The results show the difference between each combination of pore throats is largely related with the flux change. |
