摘要

In view of the problems, that first cycle effect is significant. The second cycle effect is worse in the cyclic water injection process. The physical simulation system of the cyclic water injection process in tight oil reservoirs together with the physical simulation method of the backflooding percolation resistance measurement were established by a high-pressure physical simulation experimental system for large-scale outcrops. Different permeability outcrop models were employed in the physical simulation, and the corresponding flow law under such conditions was analyzed. The results show that the dispersed phase of oil and water increase the flow resistance in the cyclic water injection process, which reduces the deliverability in certain conditions. It is suggested that the cycle should not be excessive in the cyclic water injection process.
