本文利用三维三相模拟软件对胜利油田埕岛１１断块进行了数值模拟研究，在对该区的初期开采历史进行拟合的基础上预测了未来的开发动态。着重研究了层系调整问题、自喷转抽时机、层位上（下）返对开发效果的影响等。选择了二套开发方案，方案Ⅰ：油井停喷后转抽至极限开发指标，上（下）返层位恢复自喷，停喷后转抽至极限开发指标。方案Ⅱ：油井停喷后即上（下）返层位开采，维持自喷，再停喷后合采转抽至极限开发指标。在分析对比的基础上选择最优调整方案，认为方案Ⅱ优于方案Ⅰ。 In this paper, three-dimensional three-phase simulation software was used to simulate the Chengdao 11 fault block of Shengli Oilfield. Based on the fitting of the initial mining history in this area, future developments were predicted. Focus on the adjustment of the stratification system, from the spray pumping timing, the upper and lower layers of the impact on the development of the effect. Two sets of development plans were selected. Plan Ⅰ: After the oil well stopped pumping, pumping to the limit development index, the upper and lower back layers recovered from spraying, and pumping to the limit development index after stopping spraying. Solution II: After the oil well stops spraying, the upper and lower back layers are mined to maintain the self-spraying, and then shut down to achieve the ultimate development index. Based on the analysis and comparison, we choose the optimal adjustment scheme, and consider that scheme II is superior to schemeⅠ.
