摘　　要：基于埕岛油田的油藏特征及海上条件限制,依据PI决策理论,选用酚醛树脂交联体系冻胶,高黏的聚合物乳液为过顶替液,通过分轮次注入对4口井进行了深部堵水调剖。堵水调剖后,油藏水驱效果明显改善。通过对堵水调剖效果的分析研究,对深度调剖技术实施过程中堵剂的用量、冻胶凝固时间及施工轮次进行了总结和探索,对其他海上油田开展堵水调剖具有指导意义。Based on the restrictions of the stratigraphic characteristics of Chengdao oilfield and sea conditions, according to the PI decision theory, water plugging and profile adjusting was implemented in four wells using phonemic resin as gel type plugging agents, and polymer solution of high viscosity as displacing fluid. Through analysis of water-plugging and profile-adjusting effects, and summarizing the existing problems and the measures of the next step, a helpful research on stabilizing oil output and controlling water content was proceeded, which has practical significance for water shut-offand profile control in other offshore oilfield.
