胜利油田桩52块油藏优化调整措施的效果预测

Outcome Prediction of Optimal Adjustments in Zhuang 52 Reserviors

用数值模拟方法对桩５２块油藏的开发调整方案进行了研究．在建立地质模型和模拟模型基础之上进行历史拟合，区块压力拟合的最大误差为１ＭＰａ，采出程度小于１％，区块动态含水拟合相对误差８０％以上的点都小于５％．并对所设计的６个调整方案进行动态指标预测，给出了产油、含水、采出程度随时间的变化规律，从指标对比看出，综合调整方案为最佳，其最终采收率可以提高３５％。

The development adjustment project in Zhuang 52 reservoirs has been studied by the numerical simulation. Historical regressing on the basis of establishing geological and simulating models, the biggest error of pressure regress in the area is 1 MPa, recovery is less than 1%, more than 80% of all the points of relative error are less than 5% for performance regressing in the area. We predicted the performance index for the six adjustment designs, pointed out the rule of production, cut, recovery with time. From contrast to the performance index, the optimal project is integrating regulation, and the ultimately recovery could be enhanced 3.5 %, and the best cycle of injection is 20 days.
