| 摘 要： | 沉积盆地内的地下水是油气运移的重要载体,水文地质特征是控制或影响油气藏的边界条件。在划分盆地内含水岩系的基础上,采用水动力场与水化学场相结合的方法,对海拉尔盆地乌尔逊凹陷主要含水岩系的水文地质条件进行研究,划分出3个不同性质的水文地质区带:交替活跃—氧化区带,开启程度高,不利于油气赋存;交替缓慢—弱还原区带,较有利于油气藏形成;交替阻滞—还原区带,封闭程度高,有利于油气藏形成,是油气勘探最有利的目标区域。

| Abstract: | Groundwater is an important carrier of hydrocarbon migration in sedimentary basins.Hydrogeological characteristics can control or influence reservoir boundary.On the basis of classifying water-bearing rock series,combining hydrodynamic field with hydrochemical field,the hydrogeological conditions of main water-bearing rock series have been studied in the Wuerxun Sag of the Hailaer Basin.It is divided into 3 different types of hydrogeological zones: a)actively alternating—oxidation zone,which is highly open and is unfavorable for oil and gas accumulation;b)slowly alternating—weak reduction zone,which is more favorable for reservoir formation;c)alternation blocked—reduction zone,which is closed in high degree and is conducive for reservoir formation,hence is the most favorable target area for exploration. |
