摘要:

通过引进和自主研发相结合,建立了一套大型综合性设备,对天然气、烃源岩、储层包裹体、原油、地层水等多种类型油气地质样品中的稀有气体进行纯化、富集,同时进行He、Ne、Ar、Kr、Xe全组分含量及同位素分析。开发形成了不同类型油气地质样品中稀有气体制样技术系列,建立了完整的稀有气体He、Ne、Ar、Kr、Xe全组分及同位素分析技术。选取松辽、塔里木盆地大气田典型天然气样品,开展了稀有气体He、Ne、Ar、Kr、Xe全组分含量及同位素分析,明确了长深、徐深及克拉2气田天然气样品中稀有气体He、Ne、Ar、Kr、Xe全组分含量总体分布特征,建立完善了稀有气体He、Ne、Ar、Kr、Xe多种成因类型判识图版。对长深、徐深及克拉2气田天然气中稀有气体进行了综合成因判识,提供了有效的实验技术支持。

Abstract:

Through introduction of technologies combined with independent research and development, a set of large-scale integrated devices is constructed for purification and enrichment as well as for total components abundance and isotope analyses of noble gases (He, Ne, Ar, Kr, and Xe) in different types of geological oil-gas samples (natural gas, source rock, reservoir inclusion, crude oil, and formation water). A series of noble gas sampling techniques are developed, and a complete procedure for total components abundance and isotope analyses of He, Ne, Ar, Kr, and Xe is established. These techniques are then applied for total components abundance and isotope analyses of the five noble gases in representative natural gas samples collected from large gas fields in Songliao and Tarim Basin. The general distribution pattern of total components abundance of He, Ne, Ar, Kr, and Xe in natural gas from Changshen, Xushen, and Kela2 Gas Field are clarified, and multi-origin identification maps of these noble gases are constructed. Effective supports of experimental techniques are provided for comprehensive origin identification of noble gases in natural gas from Changshen, Xushen, and Kela2 Gas Field.

Key words: noble gases, sampling technique, total components abundance and isotope analysis, distribution pattern, comprehensive origin identification
