摘　　要：弱凝胶已在渤海进行矿场试验,取得了较好增油降水效果,但有关弱凝胶与油藏适应性方面的研究成果还较少。以J油田地质模型和开发模型为基础,对井组进行弱凝胶调驱注入速度对调驱效果影响的数值模拟研究。结果表明:随着注入速度增大,井组采收率增幅和“产出与投入比”呈上升趋势,单位PV弱凝胶增油量呈先升后降趋势。The weak gel has been tested in Bohai Sea Oilfield and achieved good effect of oil and water increase,but the research results about the adaptability of the weak gel to the reservoir are still relatively few.Based on the geological model and development model of J oilfield,a numerical simulation study on the effect of injection rate of weak gel on the effect of drive transfer was conducted on the well group,and it was concluded that the recovery rate increase and"output/input"of the well group showed a rising trend as the injection rate increased,and the oil increase per unit of PV weak gel showed a rising and then falling trend.
