摘　　要：水驱面积波及系数是影响油藏采收率的重要因素,为了更高效的提高油藏采收率,以江苏油田复杂断块油藏为例,应用油藏数值模拟软件建立相同井网形式、不同沉积韵律的三维两相黑油模型,统计水驱面积波及系数,研究沉积韵律对水驱面积波及系数的影响以指导今后的现场生产。结果表明,不同沉积韵律油藏对应的各小层水驱面积波及系数具体变化规律不同,且复合正反韵律油藏各小层的水驱面积波及系数变化规律最为特殊。Water-flooding area sweep efficiency is an important factor which impacts the recovery or Oll reservoir. In order to improve oil recovery effectively,Jiangsu Oilfield is given as an example in this paper. Three-dimensional two-phase black oil reservoir model is used to get the sweep efficiency of reservoirs in the same well net and different sedimentary rhythms, in order to study the impact of sedimentary rhythm on the reservoir sweep efficiency to guide future on-site production. The result shows that the area sweep efficiency of different rhythm reservoirs have their own different variable orderliness, and the variable orderliness of area sweep efficiency in combined positive and negative rhythm formation is in the most peculiar.
