摘　　要：超稠油Ⅲ类油藏已成为风城油田SAGD开发的主力接替区块,历经3年的攻关归纳形成了适用于超稠油Ⅲ类油藏SAGD的改善开发效果技术对策。通过储层分类评价方法,明确了Ⅲ类油藏SAGD主要影响指标,运用汽腔监测手段准确描述汽腔发育动态,揭示汽腔发育规律。同时结合井组生产动态,实施形成了“暂堵调剖”“复合吞吐”等针对性增产提效措施,水平段动用程度增幅达到21%,提升了井组产油水平及开发效益。为该类油藏开发指明了方向,同时也为SAGD后续接替产能方案部署提供了技术保障。Ultra-heavy oil reservoir has become the main replacement block of SAGD development in Fengcheng oilf ield.After three years of research,the technical countermeasures to improve the development effect of SAGD suitable for ultra-heavy oil reservoir has been formed.Through the method of reservoir classif ication and evaluation,the main influence index of SAGD in the oil reservoir is def ined,and the means of steam cavity monitoring is used to accurately describe the development dynamics of steam cavity and reveal the development law of steam cavity.At the same time,according to the production dynamics of the well group,targeted measures to increase production and improve eff icien,which improved the oil production level and development benef it of the well group.It points out the direction for the development of this reservoir and provides technical support for the deployment of SAGD replacement capacity scheme.
