Authors: E.B. Topychkanova, M.V. Berbushenko, A.V. Matayev, T.V. Tomilina (Center of Geological maintenance of Surgutneftegaz OAO activity, RF, Surgut)

Key words: productive complexes, сейсмостратиграфия, ССК, литология, обстановки осадконакопления, нефтегазоносность.

A comprehensive study and the dismemberment of the Lower Middle Jurassic deposits of western areas of the West Siberian basin are carried out. A complex structure of rocks of Tyumenskaya and Gorelaya suits, defined by a variety of environments of their formation, is established. Based on the integration of seismic, well logging, core data three productive complexes, characterized by certain conditions of sediment accumulation, specific sets of traps and hydrocarbon deposits, confined to him, are selected in the Jurassic sediments. The problems of structure, formation, material composition features, seismic and geological characteristics of the productive complexes of the Jurassic, hydrocarbon traps typification are considered. Patterns of their distribution on the western periphery of the Surgut arch are shown.
