| 摘要: |
| 埕岛海上油田油层多，储层平面上和纵向上物性差异大,非均质性较强，采用分层注水工艺开发不能较好地控 制整个油藏的水驱效果。针对埕岛油田采油速度低、含水上升较快等问题，提出一种新的最优油藏动态调控方法。 该方法将油藏视为一个复杂的动态系统，以油藏开发生产净现值最大化为目标，通过求解描述油藏开发生产的优化 模型，实时优化油藏的输人输出调控参数，获取该时刻最优的生产方案。利用该方法对埕岛油田6A + B典型区块进 行的实例分析结果表明，获得的最优生产方案符合油田实际。 |

| Abstract: |
| Chengdao offshore oilfield is a multi-layers reservoir with strong heterogeneity of uneven physical properties on the vertical and horizontal direction. The technology of separated layer water-flooding was used for development. However, this technology couldn ’ t control water flooding in the whole reservoir. To solve these issues such as a low production velocity and water cut increasing rapidly，a new optimal reservoir dynamic control method was proposed. It regarded reservoir as a complex dynamic system. The optimal objective was to maximize net present value of production. Through solving the optimization model of reservoir development and production，real-time control parameters of input and output for reservoir were determined and the optimal production schedule was obtained. Typical block 6A + B of Chengdao Oilfield was analyzed by the new method. The results show that the optimal production scheme agrees well with the demand of actual field. |
