High pressure reciprocating plunger pumps are the main oil production equipment to guarantee the stable production and high yield of oilfields,and improve crude oil recovery.They are characterized with constant flow rate,high pressure and strong adaptability to the transmitted mediums(liquids).At present,there is an increase in both the difficulty in crude oil production and the demands for low running costs of water injection pump stations,the higher requirements for high reliability,high viscosity stabilizing and intelligent diagnosis control for remote operations of plunger pumps are put forward.CNPC Bohai Petroleum Equipment Manufacturing Co.Ltd.developed special technology for longer service life,higher viscosity stabilizing and intelligence through continuous digestion and innovation.The paper introduced the structure,functions,technical parameters and innovation points in high reliability plunger pumps,high viscosity-stabilizing polymer injection pumps,and intelligence diagnosis control system for plunger pumps operations.Field applications have proven that the maintenance cycles of the plunger pumps are greatly extended,the crude oil recovery is improved and the operation costs of water injection pump stations are reduced.And the digitization,standardization and normalization management level for water injection pump stations are overall improved.
