摘要： 通过对天然气地化特征、碳同位素、轻烃组成资料研究认为,准噶尔盆地腹部陆梁隆起古生界天然气具有高氮特征。其中陆南凸起石炭系和三叠系天然气为含氮天然气;石南凹陷石炭系天然气为富氮天然气。成因研究认为,这类天然气可能与岩浆岩侵人体有关。在此研究基础上,结合地质条件,推测气源为石南凹陷石炭系。

Abstract: It is shown that natural gas of the Palaeozoic exhibits high contents of nitrogen in Lu-liang uplift in the hinterland of Junggar basin, based on the analysis of geochemistry,carbon isotope and light hydrocarbon composition data. Nitrogen is present in the natural gas of the Carboniferous and Triassic in Lunan arch, and rich in the gas of the Carboniferous in Shinan sag. Origin study suggested that this type of natural gas is probably associated with magmatic intrusion, and originated from the Carboniferous in the Shinan sag.
