| 摘 要： | 根据石油成熟度梯度、原油中吡咯类含氮化合物丰度和异构体参数变化特征以及原油中高分子量正构烷烃的分布特征,结合车—莫古隆起的构造演化,探讨了准噶尔盆地中部Ⅰ区块油藏可能的油气运移方向。结果表明,研究区原油间运移分馏效应十分复杂,近期原油主要运移方向是由南向北,即油气是从南部的征1井区向沙1井、庄1井区运移。

| Abstract: | Based on researches on the distribution of maturity parameters,pyrrolic nitrogen compounds and high_molecular normal alkanes in oils of Block I in central Junggar basin,it is known that the oil migration directions of the study area are very complicated. Considering the evolution of Che_Mo ancient uplift,the authors hold that the migration distance of petroleum distributed in Well Zheng_1 is relatively short, while the migration distance of petroleum distributed in Well Zhuang_1 and Well Sha_1 is relatively long. Therefore, it can be concluded that the main oil migration direction has been from south to north recently. |
