Distinctive features of tectonic structure and oil-gas bearing capacity of Tengi-Beshbarmag anticlinorium
G.A. SuleymanovThe paper reviews distinctive features of Tengi-Beshbarmag geological structure presenting a complex tectonic unit complicated by Siazan, Klit-Ugakh and Gulakh regional faults and Siazan monocline. Siazan and Klit-Ugakh faults are the branches-apophyse of single Siazan deep fault. Upper-fault character of Hulakh overfault and formed above it same-name uplift is justified, north-west half of which is related to Khizi zone and south-east to Tengi-Beshbarmag anticlinorium. Siazan fault in the central part is presented with a failure, and in north-west and south-east parts as a cragged throw, along with which Paleogene and Upper Cretaceous sediments of Siazan monocline are overturned or fall sharply in the north-east, herewith by the extension zone of mentioned sediments do not always coincide with fault extension. The prospects of oil-gas bearing capacity of Tengi-Beshbarmag anticlinorium are connected with tectonically screened and lithologic traps of Middle Jurassic and Neocomian, and with Upper Cretaceous and Paleogene sediments with lithologic-stratigraphic and partially tectonically screened traps.
