| 摘 要： | 分析了新疆焉耆盆地侏罗系原油的物性、含氮化合物含量和储层自生伊利石的同位素年龄在纵向和横向上的变化规律,探讨了焉耆盆地侏罗系油气运移方向。由上述分析可知,该区原油密度、含氮化合物含量和自生伊利石K-Ar年龄在平面上和垂向上均呈现出规律性的变化,即:平面上自南而北这些参数逐渐降低,垂向上同一构造带内随埋深减小这些参数逐渐变小。由此表明焉耆盆地侏罗系油气运移方向在平面上是从南向北,即油气先充注宝南储层,然后依次注入宝中和宝北储层;在纵向上是从深层向浅层运移,从八道湾组向三工河组和西山窑组储层中运移聚集。 |

| Abstract: | This paper analyzes some geochemical information of Jurassic reservoir in the Yanqi basin,which includes crude oil physical property,pyrrolic nitrogen compounds and isotopic age of autogenetic illite,and also discusses the oil and gas migration direction.The result indicates that these geochemical parameters show a regular variation decreasing gradually from south to north in plane and from deep to shallow in the vertical.Based on this analysis,it is concluded that Jurassic oil and gas migrated from south to north in the lateral and from deep to shallow in the vertical: Oil and gas injected firstly into Baonan reservoir,secondly into Baozhong and Baobei reservoirs laterally,and migrated from Badaowan Formation to the reservoirs of Sangonghe Formation and Xishanyao Formation vertically. |
| Keywords: | Yanqi basin crude oil physical property nitrogen compound isotopic dating of autogenetic(illite) oil and gas migration |
