Oil-Gas Transport System in Chunfeng Oilfield in Junggar Basin

Chunfeng oilfield is characterized by far source hydrocarbon accumulation,its oil-gas transport system is the key factor of hydrocarbon accumulation.Based on the characteristics of reservoir distribution and source rocks,integrated with the comprehensive analysis of the key factor,this transport system in Chepaizi area can be divided into upper and lower conducting systems,and their effects on the reservoir-forming control have been analyzed,by which the spatial distribution and accumulation model of oil and gas in this oilfield are determined.
