| 摘 要： | 鄂尔多斯盆地镇北油田原油中含有丰富的吡咯类含氮化合物,不同层系或相同层系原油中吡咯类含氮化合物总体分布型式相似,原油中吡咯类含氮化合物以烷基咔唑为主,烷基苯并咔唑次之,未检测到二苯并咔唑。但含氮化合物绝对质量分数与相对分布差异明显,显示出明显的油气运移分馏效应。随着运移作用的加强,含氮化合物绝对浓度下降,"屏蔽"型与"暴露"型或"半屏蔽"型化合物的比值增加。根据原油中含氮化合物参数的平面分布规律可知,镇北地区原油运移方向是:镇53井区和镇221井区为自东北向西南,镇218井区为自西北向东南。

| Abstract: | There are abundant pyrrolic nitrogenous compounds in oil of Zhenbei Oilfield in Ordos Basin and these compounds are generally of similar distribution in the same formation or different formations. The pyrrolic compounds contain mainly alkycarbazoles and a little bensocarbozoles. The dibenzocarbazoles are not detected. But there are obvious differences between the absolute concentration and relative distribution of the nitrogenous compounds showing the significant fractionation effects of hydrocarbon migrati... |
