Abstract: In the process of offshore oilfield development and production,it is necessary to maintain the formation energy in the process of oilfield development and production through formation water injection,and its effect determines the quality of offshore oilfield development and production. Water injection is carried out by continuously pressurizing water injection pump to meet the requirements of design water injection pressure. With the increase of oilfield production years,the water content and water injection volume of the oilfield also increase year by year. Therefore,it is necessary to continuously improve and optimize the water injection system to ensure that the equipment operates in the best working condition area,so as to meet the requirements for the design water injection pressure of offshore oilfields. The remote control of water injection wells in offshore oilfields is optimized through the configuration of central control system to realize the remote control of water injection wells under abnormal working conditions,thus avoiding the process shutdown caused by water injection process in offshore oilfields,improving the production efficiency of offshore oilfields,and ensuring the stable and safe operation of offshore production platforms.

Key words: water injection well, water injection pump, remote control, central control system
