OIL AND GAS PROSPECTS OF ENISEI-KHATANGSKY REGIONAL TROUGH
From positions of present state of exploration, geological structure of Enisei-Khatangsky regional trough is characterized. Regional seismogeological model of clinoform complex is presented. There were outlined 18 clinoforms of northern dip with echelon-like replacement of each other and one oncoming - Taimyrskaya. Clinoforms are integrated in five megaclinoforms which with great probability appear to be separate reservoirs. Oil and gas potential prospects of the first priority exploration object - Cretaceous clinoform complex (Nizhnekhetsky and Sukhodudinsky reservoirs) with area exceeding 74000 km<sup>2</sup> are substantiated. It is given prognosis of high prospective, prospective and low prospective zones of oil and gas accumulation. Total area of prospective lands attains 35000 km<sup>2</sup> with shelf - 13000 km<sup>2</sup>, basin - more than 22000 km<sup>2</sup>. Resources of clinoform complex were evaluated by D<sub>1</sub> category (resources of HC of unassigned subsurface fund): oil - 1684,1 (recoverable - 336,8) million tons, gas - 3800,0 billion m<sup>3</sup>, condensate - 380,0 (recoverable - 190,0) million tons.
