摘　　要：针对边水驱油藏的地质及开发特点 ,提出了边水调剖技术 ,同时对调剖井点的选择、调剖剂的筛选、调剖剂用量的确定、调剖施工工艺等配套技术进行了研究。通过向优选的调剖井注入调剖剂 ,可以控制边水的侵入方向和推进速度 ,从而增大波及系数 ,提高最终采收率。 2 0 0 0年 5月到 1 1月 ,对高 1 0 4 5区块 8口井进行了边水调剖试验 ,共注入调剖剂 1 851 6m3。调剖后 ,内部井的含水率下降、产量回升 ,明显提高了区块的采收率。数值模拟预测结果表明 ,调剖增油超过 70 0 0t,投入产出比大于 1∶2。The profile control technique for a block scale has become an important means for improving oil recovery and widely used in water flooding oilfields. According to the characteristics of edge water drive reservoirs, the edge water profile control technique was presented, and the relative techniques, including choice of operation wells, selection of profile control agent and determination of agent quantity for profile control and process of profile control operation, for edge water profile control were discussed. The profile control agent was injected into the selected edge water drive wells to control the invading direction and speed of edge water. Thus the edge water displacement efficiency and ultimate recovery factor can be improved. The application of the edge water profile control technique to Gao 104 5 Block showed that the profile control agent of 18516 cubic meters was injected into eight wells in seven months in 2000, and a good effect has been achieved for interior oil wells. The water cut was declined, and the oil production rates of these wells increased. The prediction of reservoir numerical simulation shows that over 7000 tons of oil in the block will increase, and the proportion of input and output will be better than 1∶2. The efficiency of edge water drive reservoirs can be greatly enhanced by applying edge water profile control technique.
