Description

technical field [0001] The invention relates to the technical field of crude oil dehydration equipment, in particular to a visual dynamic electric dehydration simulation device for crude oil with high water content. Background technique [0002] In order to meet the requirements of crude oil transportation, oilfield well fluid usually needs to be dehydrated after production. The conventional process includes three steps: self-sedimentation dehydration, thermochemical dehydration, and electrical dehydration. However, as oilfield exploitation enters the middle and late stage, the water content of the well fluid increases greatly. In some oilfields, the water content of the well fluid is even as high as 90%, which can easily cause the electric dehydration equipment to have a super high current or even trip, making oil-water separation difficult. [0003] At present, in the existing electric dehydration simulation device, in order to increase the working performance parameters o...
