| 摘 要： | The Mazhuang gas reservoir is located in the eastern part of the Junggar Basin. Itsgas-producing pool is averagely 2000 m deep. It is a mid-shallow reservoir. The natural gasrich 2--7% of C_2-C_4 gaseous hydrocarbons is mainly composed of methane. δ~(13)C_(CH_4). valuesare--47----45‰, heavier than microbiogenic gas, and lighter than coal--type gas as well asoil--associated gas. The maternal materials of gas source rocks are primarily from the type-Ⅲ organic matter at the low--mature stage (0.5%
