摘　　要：稠油热采小断块边水油藏在蒸汽吞吐生产过程中受边水侵入影响很大,研究应用整体治理技术,按照油藏特点和水侵特征将边水侵入划分为构造部位水淹型、区域差异水淹型、条带状不规则水淹型等三种类型,分别采取立体抑水技术、分区抑水技术、节点抑水技术,优化应用多段塞组合抑水技术,优化热化学组合注汽参数,改善了小断块边水油藏控水稳油开发效果。The edge water reservoir in small fault block of heavy oil thermal recovery is greatly affected by edge water intrusion in the process of steam huff and puff production. The overall treatment technology is studied and applied. According to the reservoir characteristics and water intrusion characteristics,the edge water intrusion is divided into three types: structural water flooding type,regional differential water flooding type and strip irregular water flooding type. Three-dimensional water suppression technology,zoning water suppression technology and Node water suppression technology,optimized application of multi slug combined water suppression technology,optimized thermochemical combined steam injection parameters,and improved the development effect of water control and oil stabilization in small fault block edge water reservoir.
