description The invention provides an oil-water separation process for high-oil-content emulsified produced water. Separated high-oil-content emulsified produced water in a gas collection station is stored in a buried sewage tank, oil-water separation of floating oil easy to separate is completed through natural sedimentation, produced water enters and exits from a produced water treatment station in an automobile transportation mode, demulsification is conducted by adding a low-temperature demulsifier, oil-water separation is completed under the cooperation of an oil-water separator and a three-phase separator, and the treated produced water enters an in-station produced water treatment system, and is treated and reinjected. The problem that oil and water are transported together without a gatheringand transportation pipe network is solved, light oil prone to floating in the gas collection station is pulled away, water is gathered and transported nearby, and the operation cost is saved. The oil-water separator and the t
