摘　　要：双河油田Ⅵ油组综合含水93．4％，采油速度0．58％，多数小层强水淹，通过数值模拟等手段对双河油田Ⅵ油组强水淹层进行了潜力评价，针对剩余油分布特征及生产动态状况；利用注采结构调整、液流转向、去封、解堵打新井及对长期封堵层再利用等手段，恢复可采储量67．5×10^4t，采收率由40．68％提高到42．2％。单元递减下降，采油速度提高，开发趋势好转。Ⅵproducing section in Shuanghe oilfield is characterized by the high composite water cut as 93.4%,the production rate as 0.58%and major member being intensely water -flooded.The recovery potential of the intensely water-flooding layers is evaluated through the numerical simulation. After the measures such as adjustment of injection and recovery framework,fluid diversion,deblocking,broken down and recycling the plugged zone of long duration are used according to the distribution of residual oil and production performance,the recoverable reserves are resumed to be 67.5×10~4 t and the recovery rate is increased from 40.68% to 42.2%.Then the degression of fluid unit is contained and the production rate is enhanced,resulting in a good production condition.
