In this paper, the features of the tectonic development of the North-West Caspian Sea are considered. The selection of two main productive horizons - the Middle Jurassic and the Lower Cretaceous - is substantiated. Correlation links between the structures of the Jurassic and Lower Cretaceous deposition time are revealed. The descriptions of the main structural elements (Astrakhan arch, the zone of the South-Astrakhan uplifts, the Sarpi trough and the northern slope of the Karpinsky ridge) are given. This will allow us to further substantiate the most effective areas of geological exploration in this complex of deposits in the North-West Caspian Sea.
