摘要
轮南地区是塔里木盆地油气十分富集的重要地区，石炭系泥岩作为石炭系砂岩储层和奥陶系裂缝灰岩储层的区域性盖层，具有较强的物性封闭能力，并且其封闭能力形成时期与满加尔凹陷中上奥陶统源岩大量排烃期匹配关系较好。因此，石炭系泥岩盖层对封盖轮南地区奥陶系和石炭系油气聚集成藏是十分有利的。
Lunnan area is one of the most significant targets in Tarim in that of oil and gas were abundantly accumulated. The mudstone of Carboniferous,serving as the regional caprock of both carboniferous sandstone reservoir and ordovician limestone fractured reservoir,Owns strong capillarily sealing ability. Morever, the formation period of this capillarily sealing bed well matched for that in which oil and gas were signifccantly generated in the sowrce rock of mid-upper Ordovician in Manjiaer depression. therefore, the mudstonecaprock of carboniferous is favorable to accumulating the oil and gas in Carboniferous and Ordovician to formpools.
