Abstract
Chemical flooding is playing an important role in stabilizing oil output in Daqing, which is the largest field in China and started its chemical floods since the last 90's. In Daqing Oilfield, the chemical flooding annual output has exceeded 17 million tons; water cut has been dropped down significantly. The success of chemical enhanced oil recovery (EOR) has encouraged the increasing of chemical flooding projects largely in recent years. As a result of investment increase and experience build up, the technology of chemical flooding has been improved, especially polymer injection. The successful experience of Daqing is valuable for the development of chemical flooding EOR in other fields and countries.
Key words: Chemical, polymer, enhanced oil recovery, Daqing.
