The optimization method of control precision of injection system in well metering

Based on the analysis of the current situation of single well metering, data acquisition and control mode of oilfield injection system, the data acquisition and control mode of polymer injection volume and dilution water injection volume of single well were optimized and improved respectively. The automatic control of injection volume of single well was realized, the injection accuracy and time effect of metering and control were enhanced, and the work intensity of employees was reduced. Meanwhile, the polymer and dilution water injection volume and the abnormal alarm function of water metering regulation were increased. These make the operation of flow regulator, pump and other equipment in injection station more reasonable, and improve the operation life and efficiency of system equipment.
