摘　　要：利用原油中含氮化合物的组成及绝对浓度的变化,对江汉盆地西南缘油气运移特征进行了研究。结果表明,原油中含氮化合物的分布及组成特征较好的指示了油气运移效应,江汉盆地西南缘石油具有从生油凹陷(玫瑰桥-牛头岗洼陷)向邻近的构造高部位和断层上升盘发生侧向运移的趋势;石油在发生侧向运移的同时还沿断层发生向上的垂向运移。该结果与该区油气分布和勘探实践相吻合。Based on the composition and concentration changes of nitrogen compounds in the oil samples,this paper investigates and compares the oil migration of the southwest of Jianghan Basin.The results show that the distribution and composition characteristics can indicate oil fractionation effects.In the studied area,the oil has the lateral migration tendency from the oil-generating depression(Meiguiqiao-Niutougang Depression) to the construction of the nearby high-rise plate location and upper wall;at the same time the oil has migrated vertically along the fault upward.All these conclusions are also consistent with the regional oil exploration.
