摘要
本文在对天然气封盖层进行古埋藏史、古异常压力进行恢复的基础上，结合主力烃源岩的生排烃时间，对准噶尔盆地南缘西部天然气封盖层的有效性作出了评价。认为安集海河组对侏罗系烃源岩是有效的盖层。
Based on the restoration of the paleo burial history and paleo anormalous pressure of natural gas seals, the effectiveness of natural gas seals in western part of the southern fringe of the Junggar Basin has been evaluated combined with the hydrocarbon generating and hydrocarbon discharging time of major source rock. It is considered that the Anjihaihe Formation is the effective caprock for the Jurassic source rock, and the Sangonghe Formation and the Baijiantan Formations are effective for the Middle Permian one.
