1. A plant for oligomerizing C2 to C4 olefins to produce oligomerized alpha-olefins, with production of a fouling by-product in the form of a deposit, said plant comprising a reaction section comprising:
a reactor for two-phase gas/liquid or single-phase all-liquid oligomerization of C2 to C4 olefins in the presence of a homogeneous oligomerization catalyst and an optional solvent, and
cooling means associated with said reactor in the form of at least one cooling circuit external to the reactor and/or in the form of a jacket of the walls of the reactor,
wherein packings are disposed in the reaction section in order to increase the contact surface area per unit volume that is accessible to the deposition of the fouling by-product.
