Abstract: During the production process of offshore oil platforms,a large amount of chemical agents need to be injected,which are mainly used to improve the oil-water separation effect,the production sewage treatment effect,slow down the scaling and corrosion of pipelines,prevent the solidification of wellbore crude oil,prevent the false liquid level in containers from causing safety production accidents,and reduce the resistance of offshore pipelines. When the chemical agent inventory is insufficient,the mobile chemical agent tank with chemical agent will be transported to the offshore oil platform by shuttle ships,and the on-site operators will transfer the chemical agent in the mobile chemical agent tank to the fixed chemical agent tank by gravity flow method or air pump liquid transfer method,which has the disadvantages of slow liquid transfer speed,heavy workload,high noise and easy failure of the air pump. In order to improve this situation,a liquid transfer device for chemical agent tank driven by compressed gas was developed. The device has the advantages of low labor intensity,high operation efficiency,flexible movement,simple structure,wide application range,strong adaptability,etc. It has a good promotion and reference significance for offshore oil platforms with insufficient deck space.

Key words: chemical agents, mobile chemical agent tank, gas-driven fluid transfer device
