摘要/Abstract

摘要： 针对油田停产后地下流体如何运移分布、地层能量如何恢复、产能如何变化等问题开展油田停产后油水渗流规律及地层能量恢复程度等研究。研究中综合利用了物理实验模拟、数值模拟及油藏工程等多项方法。研究表明，油田停产期间仍存在微观油水运移，油水重新分布，油藏压力逐渐回升，地层能量逐步恢复。因此油田经过较长时间的停产后，单井产能呈先升高后降低，含水先降低后上升的特征。研究结果对长期大范围停产油田的渗流机理和开发规律认识有一定的借鉴意义。

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
