【 摘 要 】

Considered questions of structure and formation conditions of the Berrias-Lower Aptian deposits of the Gydan Peninsula of Western Siberia. Their seismogeological characteristics are given. Recognized eight seismic sequences, most of which have a wedge shape and correspond to third-order sequences. The main prospects for the search for hydrocarbon traps are associated with the Achimov petroleum complex, lenticular sandy-aleuritic beds of which have deep-water genesis. Two types of promising zones are identified for the search for lithological traps in the deposits of the Achimov Formation. One of them is associated with depocenters accumulation of clinoforms, the second - with the regional wedging distal Achimov strata in the direction of the Taimyr paleolandmass.
