摘要： 分析了鄂尔多斯盆地神木地区神3等7口井的流体包裹体，结合构造发育史、沉积埋藏史、热史和生烃史等,探讨了该区上古生界上石盒子组、石千峰组气藏形成过程中天然气的运移相态、运移通道以及成藏时间。研究结果表明,神木地区上石盒子组、石千峰组天然气共发生三次运移,其中晚侏罗世末期一早白垩世早期发生的第二次天然气运移和早白垩世末期一晚白垩世早期发生的第三次天然气运移对该区成藏起关键作用，运移相态以混合相为主。

Abstract: The analysis of fuid inclusions from 7 wells (e.g. Shen-3 Well) in Shenmu area, Ordos basin and the discussion about the phase state and passage of gas migration during the formation of Neopaleozoic Upper Shihezi and Shiqianfeng gas pools and the accumu-lated time in this area are made, according to the structural history, deposition and buried history, thermal evolution history and hydrocar-bon-generating story. Study shows that three times of gas migration from Farly Jurassic to Late Cretaceous take place in Upper Shihezi and Shiqianfeng formations, of which the second migration of end of Late Jurassic- -start of Early Cretaceous and the third migration of end of Early Cretaceous-start of Late Cretaceous play great significant roles in the gas accumulations here. The phase state of migration is dominated by the mixed phases.

Key words: Ordos basin, inclusion, homogenization temperature, natural gas, hydrocarbon migration
