Description

Technical Field

[0001] The utility model relates to the technical field of aged oil treatment, in particular to a separation device for treating aged oil in oil fields. Background Art

[0002] During the production process of oil fields, along with the production and treatment of crude oil, aged oil will be produced under the action of mechanical impurities, bacteria or chemicals, especially in sewage tanks and drying pools, where a considerable amount of aged oil is accumulated. The aged oil is seriously emulsified with water and is difficult to handle, and occupies a large amount of crude oil storage space in sewage tanks and drying pools, so it is necessary to recycle the aged oil in a timely manner.

[0003] In the prior art, when the aged oil is directly separated by a centrifugal device, the aged oil is directly added to a centrifugal separator for separation without pretreatment, and the separation efficiency of the aged oil is slow, and the separation is not evacuated. Publication No. CN221626148U discloses a separation device for treating aged oil in oil fields, which belongs to the field of oil field technology. The key points of the technical solution include a preheating tank, a device body is arranged inside the preheating tank, a separator body is arranged on the right side of the device body, and conveying racks are arranged on both sides of the top of the preheating tank.

However, it only performs preheating, has limited effect on reducing the viscosity of aged oil, and has limited separation and improvement efficiency.
