The relevance of the research is caused by the need to expand the hydrocarbon resource base of Western Siberia by engaging carbo nates reservoirs of the Upper Paleozoic Basement in the development of oil deposits. The aim of the research is to clarify the sedimentationtectonic reasons for formation of reservoirs in the upper part of the Paleozoic basement; to forecast spatial orientation of block movements and fracture zones of basement rocks depending on the tectonic transfor mations of the territory in the miogeosyncline stage of development; to assess the possibility of identifying oilpromising zones by seis mic exploration methods. The research object is the deposits of the Paleozoic basement in NorthOstaninsk oil field area of the southeastern part of Western Siberian petroleum province. Methods: allocation of homogeneous lithological packs stratigraphy in well columns; comparison of lithological heterogeneity sequence of the basement rocks with the formational composition of miogeosyncline at various stages of its development; clarification of the causes of dolomitization of organogenic carbonates that control oil deposits in the field; paleogeographic reconstruction of the North Ostaninsk area during the formation of the productive strata M1; forecast of the output of carbonate rocks on erosiontectonic base ment surface by analyzing the values of the amplitude of the reflecting horizon F2 (basement roof). Results. The concrete material shows the correspondence of the alternation sequence of basement rocks in well sections to the existing model of formational composition of miogeosyncline at various stages of its development. The authors have revealed the relation of do lomitization of organogenic limestones – the main development object, to exogenous metasomatism and forecasted the orientation of tectonic disturbances and fracturing of the rocks at occurrence of contortion folding, block faulting and uplift deformation at the sta ges of miogeosyncline and rift development of the territory. The distribution of facial sedimentation settings for the time of formation of organogenic structure was reconstructed. According to the seismic survey data, the authors forecasted the zones of output of orga nogenic carbonates, promising for searching for oil deposits, on the surface of the base.
