摘要: 运用油藏地球化学的理论和研究方法,对酒西坳陷进行了原油族群划分、烃源岩生烃史及石油运移方向研究。酒西坳陷6个油田的原油均属于同一石油族群,又可分为成熟、高成熟和低成熟3个石油组群;酒西坳陷3个生油次凹——青南次凹、石北次凹和大红圈次凹源岩的生烃门限深度分别为4150m、3000m和3300m;原油物性参数变化规律及含氮化合物咔唑类参数变化表明,酒西坳陷石油运移主要方向是由西向东,即青西油田——鸭儿峡油田——老君庙油田——石油沟油田,石油沟和老君庙油田原油垂向运移为自下而上,即L层—K层。

Abstract: Reservoir geochemistry theory and methods are applied to classifcation of oil family, study of source rock 's hydrocarbon-gener- ating history and analysis of petroleum migration direction in Jiuxi depression. Study shows that the crude oils from six fields in this de- pression belong to the same oil family which could further be divided into three groups of mature, high mature and low mature oils; the oil threshold depths of source rocks in its three sub-sags (Qingnan, Shibei and Dahongquan) range from4 150 m, 3000 m and 3300 m, re- spectively. The crude physical parameters and carbazole parameters in nitrogenous compounds indicate that the direction of Jiuxi petroleum migration should be from west toward east, ie, Qingxi field- →Yaerxia field-→Laojunmiao field- →Shiyougou field, while Shiy- ouhou and laojunmiao fields also have vertical petroleum migration with directions from botom to top, i.e., from L layer to K layer.
