摘　　要：孤岛油田中一区馆３层聚合物驱是在多油层开采、常规开发井网、污水配注条件下开展的先导试验，本文简要介绍了试验区的地质概况及试验条件，重点运用实际测试化验资料对油井的见效情况、增油效果、油井动态变化的特点进行了分析，同时对注聚井的井口压力变化、聚合物在注入井底后的滤积情况、吸水能力变化、地层流动系数变化、吸水剖面的调整、聚合物溶液的剪切情况及检测井采出聚合物溶液粘度的损失情况进行了详细的分析。Polymer flooding in the 3rd member of Guantao formation in mid No. 1 area in Gudao oilfield was a pilot test which was conducted under the conditions of commingle production,conventional developmental well pattern and injection allocation of produced water. The au-thors sketch the geological setting and test conditions in the test area. The mended situa-tion, oil increment effect and dynamic characteristics of oil wells are carefully analysed on thebasis of test and assay data. What is more,in this article they also analyse carefully the fol-lowing parameters:the variation of the wellhead pressure of polymer injection well,filteringdepoxition of polymer injected to well bottom,the variation of water-intake capacity, vari-able flow coefficient in formation,the modification of water-intake profile,the shearing ofpolymer solution,and the viscosity loss of the polymer solution taken,from monitoringwell。
