Abstract
The invention belongs to the technical field of oil field production equipment, and particularly relates to an energy-saving aged oil dehydration device. The device comprises a shell, and a heating demulsification area, a settling dehydration area, a fine selection standard area and an outer oil discharge area communicated with the fine selection standard area through an overflow port are arrangedin the shell. An anti-explosion electric heating rod is arranged in the heating demulsification area, and an aged oil inlet and a water vapor outlet are formed in the top of the heating demulsification area. A water vapor conveying pipeline is arranged in the settling dehydration area, an oil inlet communicated with a first oil outlet is formed in the side wall of the lower portion, and a secondoil outlet communicated with the fine selection standard area is formed in the partition plate where the side wall of the lower portion is located. And an adjustable flow rate control valve is arranged at the oil inlet/outlet. The inlet of the water vapor conveying pipeline is communicated with a water vapor outlet, and the outlet of the water vapor conveying pipeline is connected with a drain pipe. THE explosion-proof electric heating rod is arranged in the selection standard area. A purified oil outlet is formed in the bottom of the external oil drainage area. According to the device, the energy consumption in the actual dehydration treatment process can be reduced, meanwhile, the moisture content of the aged oil is reduced to 0.5% or below, and the device is safe and environmentally friendly.
Description
Technical field:[0001]The invention belongs to the technical field of oilfield production equipment, and specifically relates to an energy-saving aging oil dehydration device.Background technique:[0002]The production of aging oil is affected by many factors. One is the emulsified particles formed by tertiary oil recovery technology; the other is the emulsified particles formed during drilling, operation and crude oil transportation; the third is the slop oil recovered from sewage treatment; the fourth is the landing of recovery. Oil; Fifth, oily suspended matter produced under the action of bacteria. The traditional treatment process of aging oil adopts the back-mixing process and is concentrated in the sedimentation tank. The circulation of aging oil occupies the effective volume of the sedimentation tank, electric dehydrator and other equipment, which greatly affects the processing efficiency of the crude oil produced liquid In addition, the existence of aging oil makes the dehydr...
