A Segmented Electromagnetic Coupled Separator for Treating Oilfield Produced Fluid

Abstract

A segmented electromagnetic coupling separator for treating oilfield produced fluid, including a separator tank, a gas-liquid separation module, a high water content electromagnetic synergy dehydration module, a low water content electric dehydration module, a power supply system, a liquid level controller, a gas Outlet, skimmer and water outlet. The separator tank is placed horizontally, and the gas-liquid separation module, high-water electromagnetic synergy dehydration module, low-water electric dehydration module and liquid level controller are placed inside the separator body in sequence. The gas-liquid separation module is composed of an inlet rectifier tube and a baffle, the high-water electromagnetic synergy dehydration module is composed of magnets and electrodes, and the low-water electric dehydration module is composed of several vertical electrode plates placed in parallel. The present invention realizes the four-stage separation design of oil, gas and water through the above three modules and the gravity settling module in the horizontal cylinder, and has the advantages of compact structure, high separation efficiency and thorough separation. In addition, it can also handle oil-water emulsions with a wide range of water content, greatly improving the dehydration rate of crude oil.

Description

technical field [0001] The invention belongs to the technical field of multiphase separation of oil and gas gathering and transportation systems, and in particular relates to a segmented electromagnetic coupling separator for processing oilfield production fluid. Background technique [0002] At present, most oil fields in my country mainly use the combination of gravity three-phase separator and electric dehydrator for gas-liquid separation and crude oil demulsification. However, as the oilfield gradually enters the middle and late stage of development, the water content of the produced fluid rises sharply, and the content of asphaltene, colloid, and paraffin in the produced fluid is high; The emulsification of oil and water has brought great challenges to the separation of oil and water. The traditional three-phase separator based on the principle of gravity sedimentation and electric dehydration is difficult to effectively break and separate the highly emulsified crude o...

AI Technical Summary

Problems solved by technology

[0007] In summary, the traditional three-phase separator has low oil-gas-water separation efficiency, easy breakdown of electrodes, inability to efficiently treat high-water-containing crude oil emulsion, no accurate water layer monitoring system, and the entrance is critical to the harmful flow pattern of slug flow. It is necessary to invent a high-efficiency separator with remarkable dehydration effect and high dehydration efficiency for high water content and high emulsification crude oil emulsion.
