An Analysis of the Present Oil Migration Direction of Block I in Central Junggar Basin
准噶尔盆地中部Ⅰ区块现今油气运移方向研究

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.
