Let 1 -> N -> H -> H' -> 1 be an exact sequence of algebraic groups over Q_p^alg and F be a number field. Given a Galois representation r' : Gal_F -> H', we are interested in its lifts with values in H through the morphism H -> H'. We say a lift r : Gal_F -> H is minimal, if it is unramied at places where r' is unramified and is de Rham/semi-stable/crystalline at p-adic places if r' is so. In this thesis, we prove the existence of such minimal lifts in some cases.Soient 1 -> N -> H -> H' -> 1 une suite exacte centrale de groupes algébriques sur Q_p^alg et F un corps de nombres. Etant donnée une représentation Galoisienne r' : Gal_F -> H', on s'intéresse à ses relèvements à valeurs dans H à travers le morphisme H -> H'. Un relèvement r : Gal...
