Description

technical field [0001] The present invention relates to an optimization control system and method for the control parameters of a crude oil dehydration power supply, in particular to a variable step size with self-learning function for demulsification and dehydration of water-in-oil emulsions relying on the action of electric field force Self-optimizing control system and method thereof. Background technique [0002] The principle of electric demulsification and dehydration is to establish a high-voltage electric field inside the water-containing crude oil, and the water droplets collide due to the force of the electric field, and multiple small water droplets coalesce into large water droplets, which are separated from the oil under the action of gravity. According to different power supply methods, electric dehydration can be divided into DC electric field dehydration, AC electric field dehydration, AC and DC electric field dehydration, pulse electric field dehydration, et...

Problems solved by technology

Before the 1960s, it was in the exploration stage. Because some oilfields had just been developed and constructed, the dehydration effect of oilfield crude oil was unstable, which had a great impact on production.

At present, although there are many power supply methods for electric dehydration of crude oil in oilfields, they are all sinusoidal AC or approximately sinusoidal AC, which belongs to a slowly changing electric field, and the impact on the emulsified film is not strong.
