【摘要】 海拉尔盆地为中 -新生代的断陷坳陷型盆地 ,其发育演化主要经历了地壳隆起、断陷、坳陷、萎缩四个阶段。根据对成藏要素分析 ,确定出以凹陷为单元的三类含油气系统 ,各含油气系统都有各自的形成和分布规律。按其空间展布 ,又可划分为同期并列式、同期交叉式、异期叠合式三种组合形式。这些形式的有效组合 ,构成了海拉尔盆地内有利的油气聚集带。更多还原

【Abstract】 Hailaer basin is a fault depression basin of Mesozoic-Cenozoic era. The tectonic evolution of Hailaer basin can be divided into four stages: crust uplift stage, fault depression stage, depression stage, and shrink stage. Based on analysis the factors of forming oil gas accumulation, three oil gas bearing systems are recognized in Hailaer basin. Every oil gas bearing system have own formation and distribution regularity. According to their space distribution, three assemblage types were classified: synchronous parallel type, synchronous cross type and asynchronous overlap type. Their proper combination formed the favorable oil gas gathering belt in Hailaer basin.更多还原
