摘　　要：针对胜利油田边底水超稠油油藏水侵后含水率增加、产油量降低、大量剩余油未能采出等问题,以郑411区块1砂体为例,提出通过在油水边界处的水平井注入化学堵剂建立封堵隔板以遏制边底水入侵的措施。通过油藏数值模拟研究,优化了冻胶的注入层位、注入量以及注入方式。模拟封堵结果表明,超稠油油藏水平井冻胶控水稳油的效果明显,区块整体含水下降,产油上升,调堵效果显著。In view of the problems of increased water cut,declined oil production,and a large number of unproduced remaining oil after water invasion,by taking sandbody-1 of Zheng411 block as an example,the injection of chemical plugging agent in the oil-water boundary of horizontal well was put forward so as to build block partition measures to curb side bottom water invasion.Through reservoir numerical simulation,the injection layer,injection volume and injection mode of gel were optimized.Simulation plugging results show the water control and stabilizing oil effect is obvious,with decreased overall water cut,increased oil production and remarkable plugging effect.
