摘　　要：“2+3”调驱技术是将调剖与驱油有机结合,充分发挥驱油、调剖的协同效应,依靠前期调剖,扩大了后续驱油剂在油层中的波及体积,最大限度发挥驱油剂的驱油效率。通过筛选适合濮城油田Es_2~上(2+3)油藏地层条件的驱油剂和调剖剂用于现场试验,提高了油井产油量,取得了良好效果。2 + 3'profile control and displacement technique is to combine the profile control with oil displacement to make full use of co-effect of displacement and profile control, rely on early profile control , expand sweeping volume in reservoir of consequent oil displacement agent, thus to make full use of displacement efficiency of the agent. The displacement agent and profile control agent suitable to geologic conditions are selected for field test in (2 + 3) reservoir in the upper menber of Es2 in Pucheng Oilfield, by which oil production is raised, good result is achieved in the Oilfield.
