摘要：

中国北方中生代盆地的发育具明显阶段性。按主要构造幕可划为六个沉积实体,其展布格局、沉积旋回、沉积体系、改造变形、油气赋存等差异显著。多数中生代盆地,属多层次结构的叠置盆地。从生、储油层的配置关系,可分出三种类型十二种型式的油气赋存类式。新疆三大盆地的"古生中储"是今后增储增产的主要类型。"二连"、"酒西"式是松辽-华北,海拉尔-二连-巴丹吉林,以及河西走廊油气的主要赋存型式。

Abstract:

The tectonic evolution and basin development of the Mesozoic in North China are characterized by stages.Accordingly,the Mesozoic Erathem can be divided into six sedi-mentary entities:1.P22-T1 or T1+2;2.T2+3 or T3;3.J1+2;4.J3-K1;5.K2;6.K3-E1.Most of the Meso-Cenozoic basins in North China have vertically multilayer texture;different sedimentary entities are separated by uncomformities,disconformities or para-conformities.This kind of multilayer textures,named as superimposed basins,were result-ed by the superimposition of sedimentary formations formed in different basin-forming stages.The superimposition of the basins could be divided into three types,that is intra-overlapping,lateral overlapping and drape and five styles such as composite,mosaic-like,cross,single-basin and multi-basin drapes.Hydrocarbons usually occur in complecated su-perimposed basins.Through the comparison of hydrocarbon occurrences,it is suggested that the Paleozoic-generated Mesozoic reservoirs will be the main type within three marjor basins in Xinjiang,and Erlian and Jiuxi types will be the main types in Songliao-North China,Hailar-Erlian-Badan Jaran and the Hexi corridor region for hydrocarbon exploration.
