摘　　要：面12区沙三上亚段属于稠油油藏,综合含水高达97.6%,采出程度高,为21.2%,采油速度低,为0.15%,常规措施挖潜难度大、效果差。通过开展沉积微相研究,细分流动单元,并结合油藏监测资料,分析剩余油分布规律,实施水平井整体挖潜,采油速度提高至0.58%,提高采收率2.7%。The Esupper3 reservoirs in Block Mian 12 belonged to heavy oil reservoirs with integral water-cut as high as 97.6% and high degree of recovery of 21.2%,oil production rate was as low as 0.15%,it was difficult for tapping the potential with conventional measures,thus production effect was poor.Through micro-facies study,subdivision of flow units,and in combination with reservoir monitoring data,the rules of residual oil distribution are analyzed,horizontal wells are used for tapping the potential,oil production rate is raised to 0.58%,2.7% of oil recovery is enhanced.
