摘　　要：油田经过长期注水开发,注采井网遭到损害,油藏平面波及系数和纵向波及系数变差,水驱效果变差,储量未得到有效开发。深部调驱技术是以深部调剖为主,在"调"的基础上又结合了"驱"的效果,并具有提高波及系数和驱油效率的双重作用。介绍PI选层决策技术、调驱处理半径的确定以及现场施工常用参数的确定。After a long-term waterflooding, the injection-production well pattern encounter damage, the plane and vertical conformance efficiency of the reservoir and the water displacement effect get worse,the reserve volume can＇t be effective developed. On the basic of the ＂modification＂ ,the deep profile modification and oil displacement technology combine the effects of the ＂displacement＂.The deep profile modification and oil displacement technology have dual effect ,that it can improve the conformance efficiency of the reservoir and the efficiency of oil displacement. This paper introduces the PI decision technology of formation selection, and how to calculate the working radius and the other parameters of the deep profile modification and oil displacement operations.
