The shallow-buried natural gas is a hot topic in the exploration and basic study of natural gas,and has become a new important petroleum-exploration field in the Junggar Basin.Based on a case study of the central Junggar Basin,the multiple origins of the gas are revealed in this study.The results show that the shallow-buried gases in the study area have multiple origins,mainly including oil degradation gas,oil-type gas and coal-type gas with different sources.
