| 摘 要： | 准噶尔盆地阜东斜坡侏罗系头屯河组油藏是最近几年发现的新油藏，原油横向运移研究极少.在对阜东斜坡侏罗系地层特征和储层物性特征分析的基础之上，结合油源对比和油油对比地化研究，综合分析了原油的二次运移.结果表明:阜东斜坡侏罗系头屯河组原油主要来自西部阜康凹陷的中-下侏罗统和中二叠统烃源岩的混源，原油自西向东对侏罗系头屯河组储层进行充注.头屯河二段的地层厚度、砂地比、孔隙度和渗透率条件均好于头屯河三段和头屯河一段，可能为主要的油气横向运移的输导层.

Lateral Migration of Jurassic Toutunhe Formation in Fudong Slope,Junggar Basin |
| |
| Abstract: | Few studies have been done on the petroleum lateral migration in the newly discovered oil reservoirs in the Jurassic Toutunhe Formation in the Fudong slope, Junggar basin. The process and mechanisms of the petroleum lateral migration of Jurassic in the Fudong slope were investigated based on the geological analysis of the strata, porosity and permeability of the reservoir rocks and geochemical study on oil-source correlation and oil-oil correlation in this study. The results indicate that hydrocarbons of the Jurassic Toutunhe Formation in Fudong slope were primarily derived from the mixing of the Middle-Lower Jurassic and Middle Permian source rocks of the western Fukang depression and migrated along the axis from west to east. The thickness, sand/strata ratio, porosity and permeability of Toutunhe 2 member are all better than those of Toutunhe 1 member, which makes it the main carrier beds of hydrocarbons lateral migration. |
