Abstract

Abstract: The seepage characteristics of underground fluid and the formation energy of an oilfield shutdown for over 15 months were studied focusing on underground fluid distribution,formation energy recovery and field production after shutdown period. Physical modeling experiment and numerical simulation were synthesized and applied in this study. The results indicates that the micro movement and redistribution of oil and water were observed, and the reservoir pressure gradually rose again with the gradual recovery of formation energy under the shutdown. Therefore, the well production first increases and then decreases, and the water cut first decreases and then increases after long-term shutdown. It is provided a new angle for studying the seepage characteristics and development laws of long time wide-range shutdown oilfields.

Key words: long-term shutdown, oil and water migration and distribution, seepage flow discipline, reservoir pressure recovery, production performance
