摘　　要：本文从盆地演化与改造特征出发，探讨了巴彦浩特盆地的油气赋存条件及油气远景。该盆地为一叠合盆地，后期改造强烈。改造残留盆地的主要勘探目的层为石炭系海相和海陆过渡相地层，地面和井下油气显示较普遍；在南部拗陷，侏罗系可能有一定勘探远景。除自生自储类型以外，油气运移聚集主要与多期区域性不整合面有关。根据不同地区的改造特点、强度和保存条件等方面的差异，将盆地成藏单元划分为：东部拗陷西北部的叠合一再生型，南部拗陷中、东部的改造一保存型，东部拗陷西南部和东部的改造一再生型，南部拗陷西部的改造一破坏型。其成藏条件和油气勘探远景依次变差。Hydrocarbon occurrence condition and potential in Bayanhaote basin was researched from evolution and reformation characteristics. It is a superimposed basin and underwent strong later reformation. The main exploration targets are carboniferous marine facies and transitional facies strata and evidences of oil and gas are general in ground and downhole in the reformation remnant basin, but the Jurassic strata have definite exploration prospect in the north of the basin. Beside self-generation and self-reservoir type, petroleum migration relate to mult-stages territorial uncomformable surface. According to difference of reformation characteristics, intensity and conservation condition, reservoir units are divided into different types as follow： superimpose- regeneration types in northwest of the eastern depression, reformation-conservation type in middle and east of the southern depression, reformation-regeneration destruction in west of the southern depression and sequentially become variation. in southwest, east of the east depression and reformation- their reservoir condition and petroleum exploration potential
