摘　　要：根据宋芳屯油田芳17区块的动、静态数据,首先用Petrel软件建立相控地质模型,然后应用Eclipse软件进行数值模拟,对区块井网开发指标和井网剩余油变化进行预测分析,同时将全区及分层采出程度与含水率理论关系曲线和实际数据曲线进行对比,评价区块井网的适应性.结果表明:该区块含水率达到50%后,具有提液能力,最大提液幅度为目前的1.5倍;数值模拟预测到综合含水率达98%时,剩余油饱和度场仍有大量剩余油集中区域存在;井网适应性差,应调整该区块井网加密和注水方式.To provide a basis for the well network further optimization adjustment of Daqing Fang 17 block,and to produce theoretical guidance for actual production of other blocks according to dynamic and static data of the block,the facies controlled geologic model is built by Petrel software,then numerical simulation is progressed with Eclipse software,the development index and remaining oil variable condition of present well pattern in Fang 17 block are forecast.At the same time,the theoretical relation curves of recovery degree in the whole block and different layers and water cut are compared with real data curves,the pattern adaptability in Fang 17 block is evaluated.The results indicate that after water cut of the block reaching to 50%,the ability of enhancing liquid producing capacity is attained,and the maximum is 1.5 times the current,according to numerical simulation.When the composite water cut reaches 98%,abundant residual oil still resides in the residual oil saturation field.For the adaptability of well network is poor,the adjustment of well pattern thickening and water injection mode should be practiced.
