The present invention relates to a process for the oligomerization of C2 to C4 olefin(s) in a gas/liquid or all-liquid oligomerization reactor (c) using a solvent, an oligomerization catalyst and olefin(s), in which compression and premixing are performed between a liquid phase comprising the solvent and a gaseous phase comprising said gaseous olefin(s) by a multiphase pump (b), with partial or total dissolution of the olefin(s) of the gaseous phase in the liquid phase and/or premixing between the two phases, before introduction of the premix obtained into said reactor.
