【摘要】 二甲基咔唑在惠流构造脊油藏中的分布具有规律性。在惠流构造脊西段 ,上部油藏原油中 1,3 和 1,6 二甲基咔唑的丰度相对较高 ,而下部油藏原油中 1,4 和 1,5 二甲基咔唑的丰度相对较高。这一特征不是运移分馏所致 ,可能反映惠流构造脊西段存在上、下两个相对独立的油气运聚系统。惠流构造脊东段流花油田的原油中 ,1,4 和 1,5 二甲基咔唑具有较高的丰度 ,这可能反映流花油田的原油是通过下油气运聚系统聚集成藏的。更多还原

【Abstract】 The dimethylcarbazole distribution in crude oil from Hui、Liu Structure Ridge(HLSR), the Pearl River Mouth basin, has displayed some regular changes. In the west part of HLSR, 1,3、 and 1,6、dimethylcarbazoles are relatively higher in abundance in the upper reservoirs, and 1,4、 and 1, 5、dimethylcarbazoles are relatively higher in the lower reservoirs. These patterns can not be attributed to petroleum migration, but may indicate that there are two (upper and lower) separated systems of petroleum migration and accumulation in the west part of HLSR. In Liuhua oil field in the east part of HLSR, 1,4、 and 1,5、dimethylcarbazoles are quite higher in abundance, possibly showing that the field is formed by the lower system of migration and accumulation.更多还原
