摘要
海拉尔盆地位于中国北部边陲，是中国板块与西伯利亚板块在海西期缝合带上发育起来的中新生代断－拗盆地．从侏罗纪开始，由于地幔隆起诱发拉张，在区域内首先形成断拗；白垩纪后期由于岩石圈冷却，地壳沉陷而形成拗陷．盆地演化经历两大时期、六个阶段，发育多套生储盖组合，油气资源丰富，主要聚集在北西向的传递断层带，形成多种圈闭类型．
The Hailar Basin which consists of a faultdown and a depression is a Meso-Cenozoicbasin located in the frontier of north China,developed on the Hercynian sutured zone be-tween Chinese and Siberian plates.The faultdown occurred in the beginning of the JurassicPeriod due to mantle rising and crustal extension,then in the Late Cretaceous Period,thedepression developed because of lithosphere cooling and crustal subsidence,Therefore,it is suggested that the basin must have experienced two major periods composed of six geo-logical stages with several source rock,reservoir and cap assemblages developed.More-over,oil/gas source is abundant in the basin and the oil/gas predominantly accumulated ina NW trending progressive fault belt with various trap types.
