【摘要】 徐家围子断陷是松辽盆地北部深层最重要的生气断陷,文章以层序地层学为指导,以最新三维连片处理地震资料为基础,以传统的组段界面分层特征为标准,从地震和钻井上对徐家围子南部断陷登娄库组各层序底界面特征进行了分析。同时,从控制油气运移、对储集层物性的改善,有利于圈闭的形成等方面,分析了沉积演化过程中形成的不整合面对油气的地质意义。更多还原

【Abstract】 Xujiaweizi is important depression that can produce gas.With the theory of sequence stratigraphy,on the base of seismic data and on the standard of characteristic of typical sequence formation,characteristic of every sequence formation of Denglouku group in the southern depression of Xujiaweizi is analyzed.At the meantime,the significance of oil geology of unconformity formed in deposition process influencing on oil and gas is analyzed further from the respectives of controlling oil and gas transportion,improving physical property of reservoir and being good at forming traps.更多还原
