The polymer flooding of the 52+3 Formation in Gudong oil field is the first large scale commercialextending test area Because of the Problems such as: intensive injection and recovery in the Process ofwater drive, varied characteristics of reservoir properties, large serious channel, the high and unevenformation Pressure, uneven injection-production of boundary well, it resulted in low efficiency inreducing water and enhancing oil in the early time of polymer injection. In view of the Problem existed inpolymer injection area and the remaining oil distribution, the paper mainly introduced the matchingtechniques and better method of polymer flooding, and gave a brief evaluation of polymer flood. It is ofpractical and guiding significance to the same type of reservoir and production block.
