Abstract

The invention relates to an electromagnetic field emulsion breaker which comprises an electric field generating part, wherein a magnetic field generating part is arranged on the periphery or in the electric field generating part; the electric field generating part comprises a metal pipe section with a flange; an electrode is arranged in the metal pipe section with the flange and the electrode is fixed at the top of the metal pipe section with the flange through an insulating hanger; the electrode is connected to a supply transformer through an electrode bar; the metal pipe section with the flange is grounded; the magnetic field generating part is an annular magnet. By applying an electric field to a magnetic field, the electromagnetic field emulsion breaker disclosed by the invention enhances an emulsion breaking effect through a collaborative action of the electric field and the magnetic field; the emulsion breaker is mainly applicable to crude oil and finished oil, and mounted before crude oil electric desalting or electric dehydration, can reduce electric desalting or electric dehydration current, so as to reduce energy consumption and to improve adaptability and stability of the device. The emulsion breaker can also serve before a crude oil three-phase separator to improve separation efficiency, as well as in various two-phase separation places.

Description

technical field [0001] The invention relates to a magnetic field demulsifier, which is a strengthened demulsifier used for crude oil electric desalination or electric dehydration and separator. Background technique [0002] As the oilfield development enters the late stage, the continuous development of the production technology, such as the application of technologies such as tertiary oil recovery water injection, polymer injection, ASP flooding, planing, and plugging removal, has added a large amount of chemical liquid to emulsify the crude oil produced in the oilfield The degree is getting more and more serious, the crude oil emulsion becomes more stable, and the conductivity is enhanced. When a high-voltage electric field is applied, the current will increase, or even short-circuit, and the dehydration will become more and more difficult. It is difficult for conventional electrochemical second-stage dehydration to achieve Requirements for export indicators. [0003] Wit...
