When the field enters the high water content late stop stage, the remaining recoverable reserves are getting less and less, and the oil production decreases more and more seriously. The use of polymer injection for oil recovery is an important technical measure to increase recoverable reserves and improve recovery. The process technology and equipment of Maotian polymer injection exploitation are more complex than conventional exploitation, and the degree of automation control is relatively high. In recent years, many relatively mature safety management systems and operating procedures have been formed in the process of polymer injection exploitation, but they need to be further standardized and promoted. Therefore, this standard is compiled on this basis. This standard is proposed and managed by the Petroleum Industry Safety Professional Standardization Technical Committee. The drafting units of this standard are: Safety Supervision Department of Daqing Petroleum Administration Bureau, No. 1 Oil Production Plant of Daqing Petroleum Administration Bureau. The main drafters of this standard are Zhiwen, Zhao Dongliang, Wu Zhonglin, Chen Lei, He Yuehui, Sun Jiming 1 Scope
