摘要
塔里木盆地轮南地区石炭系直接覆盖在奥陶系之上，是奥陶系裂缝型灰岩储层的区域性封盖层。不仅毛细管封闭能力强，而且具有较强的压力封闭能力。虽然其压力封闭能力形成时期晚于烃源岩火量生烃期，但对该区已聚集油气的保存是十分有利的。
The Carboniferous lay directly over the Ordovician in the Lunnan area, Tarimbasin,which acts as the regional seaiing bed for Ordovician fractured limestone reservoir,with good caplliary and pressure seal properties.Although pressure sealing process occurredlater than the period of major hydrocarbon generation,it favors the preservation of accumu-lated hydrocarbon in this area.
