| 摘 要： | 东湾背斜位于准噶尔盆地南缘,采用多种地球物理及地质方法,通过多次论证,证明构造是落实的,且其烃源岩、储集层以及盖层条件都较好,但2003年完钻的东湾1井钻探结果却无任何油气显示。在深入了解准噶尔盆地南缘区域构造背景的基础上,探讨了东湾背斜的构造特征、构造演化过程及油气成藏条件,总结出东湾背斜的油气聚集规律,指出在东湾地区可能存在的两种油气藏模式,最后提出下步有利勘探目标区。

| Abstract: | It is proved by geophysical and geological means that the Dongwan anticline located in the southern fringe of the Junggar Basin does exist. Here there are better hydrocarbon source rocks and the conditions are favorable for formation of reservoir and cap rocks. But, results from drilling of Dongwan 1 well, finished in 2003, show no indication of oil and gas occurrences. Based on a comprehensive analysis of regional tectonic background of the southern fringe of the Junggar Basin, the structural characteristics, the process of tectonic evolution and conditions of petroleum geology of Dongwan anticline were fully discussed, and the rules for oil and gas accumulation were summarized in this paper. Two types of potential reservoir-forming models were proposed for the Dongwan area. Finally, the favorable targets for next stage exploration in this area were pointed out. |
