河南油田研究院和四川联合大学共同攻关完成了“九五”国家重点科技攻关专题——“高温耐盐聚合物驱油剂研制”近日通过国家级评审验收。该专题主要是针对目前我国东部主力油田已进入开发后期阶段,油井含水上升快,产量锐减,开采难度越来越大,靠聚合物驱油开采的剩余储量多属75℃以上、高矿化度资源,继续提高 Henan Oilfield Research Institute and Sichuan Union University to tackle key issues such as “95” national key scientific and technological topics - “high temperature salt polymer flooding agent” recently passed the national assessment acceptance. This topic mainly aims at the fact that the main oilfields in the eastern part of our country have entered the later stage of development and the water cut of the oil wells has risen rapidly and the output has dropped sharply. As a result, the exploitation is more and more difficult. The remaining reserves by polymer oil recovery are mostly above 75 ℃, Degree of resources, continue to improve
