The present invention discloses a novel catalyst system which can selectively oligomerize olefins including ethylene, and can trimerize and tetramerize olefins, and a method using the same to prepare olefin oligomers, which is different from what has been reported so far. Catalyst systems for the oligomerization of olefins. The present invention provides a catalyst system for olefin oligomerization and a method for preparing olefin oligomer using the catalyst system, the catalyst system including a ligand compound represented by Chemical Formula 1; a chromium compound; and an alkyl metal compound. |
