摘　　要：为改善辽河油田高18块调驱效果,开展了弱凝胶调驱提高采收率数值模拟研究.根据该区块的地质油藏条件,建立三维地质模型.在历史拟合的基础上,对弱凝胶调驱注入参数进行了优化设计,并进行指标预测.研究结果表明,弱凝胶最佳注入量为0.2 PV左右,合理注液速度为50 m^3/d左右,最佳调驱时机为综合含水率68.5%时,调驱效果最优,最终采收率为28.7%,含水率最低值为59.4%,含水率下降了9.1%.该设计方案能有效地达到降水增油和提高原油采收率的目的.In order to improve the profile control and flooding effects in Gao 18 blocks of Liaohe oilfield, we took the weak gel profile control flooding numerical simulation study to enhanced oil recovery. According to the geological conditions of the reservoir in Gao 18 block, we established a 3D geological model. Based on the history matching, we optimized the injection parameters, and predicted the development indexes. The results show that, the weak gel reasonable injection speed is about 50 m3/d, the optimum injection volume is 0.2 PV, the best opportunity to take the profile control and flooding treatment is the water cut 68.5%. The ultimate oil recovery is 28.7%, the lowest water cut rate is 59.4%, the water cut decreased by 9.1%. The optimal design can effectively realize the purposes of precipitation increasing oil and enhance oil recovery.
