摘　　要：根据河南古城油田B12 5区地层结构疏松及注水温度高于地层温度的特点 ,将聚丙烯酰胺 (HPAM) -酚醛树脂凝胶用于稠油调剖 ,并合理地控制成胶时间 ,保证施工过程中在地面不交联、在地下能够充分交联 ,确保施工的有效性和安全性。在该区调剖施工 6井次 ,施工后增油效果显著。According to the geological conditions of loose strata character and high temperature of injected water of block B125 heavy oil reservoir in Henan Gucheng Oilfield,the gel of HPAM-phenolaldehyde resin was used in profile modification of heavy oil block.By controlling the gelation time reasonably,we ensured profile modification system crosslinking only underground, and efficiency and safety of work. The gel had been applied to six wells in this block.The oil yield was significantly increased.
