Abstract

Abstract: The hydrocarbon in Mobei arch reservoir is Permian matured and over-matured oil and gas which mainly comes from the depression to the west of Well Pen 1. The sedimentary cap-rock here could be vertically divided into three structural units, namely the Permian-Triassic, Jurassic and Cretaceous-Quaternary. The hydrocarbon are mainly migrated through the faulting and better reservoir are the first to accumulate hydrocarbon to form oil-gas reservoir. The Sangonghe formation is characterized by Jurassic sand with great thickness and vast distribution, so it is difficult to form lithologic trap, and the reservoirs mainly occurred as structural trap. The deep buried Triassic- Permian traps have quite good conditions for hydrocarbon accumulation.

Key words: Junggar basin, center, depression, Jurassic, reservoir formation, condition, reservoir distribution
