|Tabulata lones as a base of separation and correlation of ordovician – devonian oil-gas bearing strata of southeast part of West-Sibirian plate|
|Coralls biostratigraphic succession is determined on the basis of monographics Tabulata’s description of the Paleozoic southeast part of the West-Siberian plate. 11 coral biostratons are described, which cover a stratigraphic range from the Upper Ordovician up to the Upper Devonian (Frasnian). The regional biostratigraphical zonality, which reflects evolutionary stages of biota development, was established on the basis of detailed investigation of morphological variability of Tabulata’s species and subspecies. The succession of Tabulata lones in the Paleozoic allows us to differentiate the Paleozoic producing strata. Tracing of these lones in other regions allows us to correlate not only discovered oil and gas deposits, but also to identify new industrially significant fields.
Key words: zonality, Tabulata, lone, strata, oil and gas deposits, West Siberian plate.

|New data on the geology and petroleum potential of the Maloichsky field Paleozoic of Western Siberia|
|Stratigraphic and facies regularities of fracture reservoirs’ developing of the Maloichsky field are revealed. Morphology of petroleum deposits as well as morphology of fluid-tectonic processes within reef massifs is substantiated by focal hydrocarbon generation on depth. Peculiarities of distribution of fracture reservoirs of reef type allow us to forecast high debit areas and optimize network of producing boreholes.
Key words: oil, fracture reservoir, focal generation, forecast, reef.
