摘要
古、中生代盆地发育受基底断裂控制,呈现由南向北迁移的特征。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,将盆地成藏单元类型划分叠合—再生型、改造—保存型、改造—再生型和改造—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 were discussed from evolution and reformation characteristics.Fundamental fault controlled development of the basin in Paleozoic and Mesozoic Era and migrated from south to north.Besides self-generation and self-reservoir type,petroleum migration is related to multi-stage territorial unconformable surface.According to difference of reformation characteristics,intensity and conservation condition,reservoir units are divided into different types as follow： superimpose-regeneration,reformation-conservation,reformation-regeneration,and reformation-destruction types,and their reservoir condition and potential petroleum exploration become worse sequentially.
