Recently, the Zhongyuan Oilfield Petroleum Engineering Technology Research Institute has carried out polymer flooding technology in the 16th block of Wenming Zhaiming
.
The polymer flooding project is a subtopic of the "130+2" cost reduction and efficiency enhancement project in the Dongpu Old Area of Zhongyuan Oilfield
.
Since the establishment of the project, the research personnel of the Petroleum Engineering Technology Research Institute have carried out detailed research on the high-salt characteristics of the Zhongyuan Oilfield, and developed a temperature-resistant and salt-resistant polymer composite system whose thermal stability is 30% higher than that of conventional polymers.
Up to now, polymer flooding has been implemented in 2 well groups, and a total of 10,675 cubic meters of polymer solution has been injected.
