摘　　要：侏罗系是鄂尔多斯盆地石油开采最早的层系之一。规模开采已历40余年，大多数侏罗系油藏已进入开发后期，具有高含水、高采出程度的特点，常规的注水开发提高采收率难度大。2008年优选H201区开展先导试验，通过优选注聚体系。优化注采参数、注聚参数等取得了良好的效果。主要针对该区聚合物驱油现场实践与认识进行剖析，为后期侏罗系双高油藏提高采收率做好技术储备。As one of the earliest developed series of resercoirs in Ordos Basin, the Jurassic System has been commercially recovered over 40 years. Most Jurassie reservoirs have entered the later stage of development with characteristics of high watercut and high reeovery percent of reserves. Therefore, it is so difficult to EOR with tonventional waterflooding. The H201 wellbloek was preferal）ly selected for pilot test in 2008. Good resuhs are obtained by selecting the besl polymer injection system, optimizing injettion and production parameters and polymer injection parameters. The field practice and understanding of polymer flooding in the block were mainly dissecled, in order to provide good technical reserves for later EOR of Jurassic reservoirs with high water-cut and high recovery percent of reserves.
