The research on a new technology for improving the fluidity of the crude oil at normal temperature or even low temperature and the application of the technology in pipeline transportation have very important significance for ensuring the safe operation of the pipeline and realizing the energy conservation and consumption reduction of the pipeline.
At present, the techniques used in the transportation of highly viscous crude oil are: heating viscosity-reducing conveying, diluting viscosity-reducing conveying, emulsifying viscosity-reducing conveying, modifying viscosity-reducing conveying and the like, but the technologies have certain defects and shortcomings. For example, heat detackifying has the following disadvantages: the oil transportation energy consumption is high, and the economic loss is large; the heating station is arranged, so that the investment of pipeline construction and the operation management cost are increased; the stop of transportation and the restart of transportation are difficult, and the long stop of transportation can cause the disastrous consequence of the blockage of the coagulation tube; if the crude oil in the pipeline is replaced by the substituted oil product under the working conditions of starting and stopping, the process is slightly complicated.
In order to explore a new technology for improving the flowability of crude oil, researchers have proposed a new method for improving the flowability of crude oil by high-voltage electric field treatment according to the mechanism of electrorheological fluid. The technology has the advantages of obvious characteristics, safety, high efficiency, simple operation and low energy consumption. The high-voltage electric field viscosity reduction technology can also be applied to the aspects of pipeline high-viscosity crude oil transportation, ocean deepwater pipeline oil transportation, engine efficiency improvement and the like.
