【摘要】 根据含油气系统划分的基本方法,海拉尔盆地贝尔凹陷可以划出3个含油气系统,即铜钵庙组含油气系统、南屯组含油气系统、大磨拐河组含油气系统。3个含油气系统的关键时刻趋于一致,均为伊敏组末期。油气运聚单元的划分有利于认识盆地内油气的分布聚集规律,根据油气运移分隔槽及隔挡条件,可将铜钵庙组含油气系统划分为2个油气运聚单元,南屯组含油气系统划分为6个油气运聚单元,大磨拐河组含油气系统划分为3个油气运聚单元。更多还原

【Abstract】 According to the standard of the traditional petroleum system, there are three petroleum (systems) in the Beier depression, Hailar Basin, China. They are the Tongbomiao, Nantun and Damoguaihe Formation petroleum systems. Three petroleum systems have roughly the same critical moment-final-stage of the Yimin Formation. The direction and path of oil-gas migration and the advantageous reservoir are the main factors of controlling oil-gas accumulation. According to the direction of oil-gas migration, conveyer and sealing conditions, two units of oil-gas migration and accumulation can be divided in the Tongbomiao petroleum system, six in the Nantun petroleum system, and three in the Damoguaihe petroleum system.更多还原
