[57] Abstract: The invention comprises a process for prerefining and hydroconversion of a heavy crude oil, topped or not, for producing a prerefined synthetic crude, in which said feed passes into a hydrodemetallization section comprising at least two switchable reactors, then at least a proportion of the demetallized effluent is hydrocracked in a hydrocracking section, then at least a proportion of the hydrocracked effluent is optionally hydrodesulphurized, then at least a proportion of the effluent is fractionated. At least a proportion of the heavy fraction thus obtained is subjected to a deasphalting. The deasphalted fraction is recycled to the process.
