Characteristics of morphotypes of Neocomian clinoform formations in the north of the West Siberian lowland in connection with the peculiarities of sedimentation processes

Abstract

In the article, based on a relatively deep-water clinoform model of the Achimov strata structure based on the analysis of sedimentological processes and 3D seismic data, the characteristics of the morphological types of clinoform formations, structural features and sedimentation of the Lower Cretaceous deposits in the zone of counter clinoforms are given, a new type of hydrocarbon traps is identified within this area, their seismic images are presented. It is noted that in the zone of east-dip clinoforms (the Ural source of demolition), it is necessary to evaluate the prospects for oil and gas potential of the section based on the analysis of seismic and gravity survey and logging data, in order to predict fractured reservoirs.
