摘　　要：目前渤海油田已经逐步进入高含水期,其中Q油田存在高含水、高采出程度,储层非均质性强,存在水流优势通道等问题,迫切需要对储层进行降水增油。通过实验研究和现场实例描述了聚铬交联PPG预交联组合调驱技术在Q油田的实际应用情况,实际证明,此项技术对海上油田适应性较好、效果较为明显。为海上油田降水增油提供了宝贵的实践经验和实验数据,可以指导未来海上油田调剖调驱技术的广泛应用。At present,Bohai oilfield has gradually entered the high water cut stage.Among them,Q oilfield has some problems,such as high water cut,high recovery degree,strong reservoir heterogeneity and dominant water flow channel.It is urgent to reduce water cut and increase oil production in the reservoir.In this paper,the practical application of polychrome crosslinked PPG pre-crosslinked combined profile control and flooding technology in Q oilfield was described through experimental research and field examples.The practice showed that this technology had good adaptability and obvious effect on offshore oil fields.It provides valuable practical experience and experimental data for precipitation and oil increase in offshore oil fields,and can guide the wide application of profile control and flooding technology in offshore oil fields in the future.
