Description

technical field [0001] The invention relates to the technical field of high voltage and insulation, in particular to a method for preparing dehydrated crude oil with a dynamic visualization simulation device for electric dehydration of crude oil. Background technique [0002] Electric dehydration of crude oil is an indispensable link in the process of crude oil processing. With the widespread application of tertiary oil recovery technology and the gradual entry into the middle and late stages of oilfield exploitation, the produced crude oil has a high degree of emulsification and high viscosity, which makes electric dehydrators appear frequently. The "collapse" phenomenon of the electric field, the water content of the treated oil and the oil content in the water have exceeded the standard for many times. The electric dehydration equipment of the electric field adopts the method of improving the power supply parameters of the dehydration power supply and changing the distanc...
