鄂尔多斯盆地延长组长7段与威利斯顿盆地Bakken组致密油形成条件的对比及其意义
Comparison of Chang 7 Member of Yanchang Formation in Ordos Basin with Bakken Formation in Williston Basin and Its Significance
摘要
Abstract
Since the tight oil of Bakken Formation in north America developed successfully in industry,the tight oil has become a hot spot in the exploration and development of unconventional oil and gas resources,and the Chang 7 Member of Yanchang Formation in Ordos Basin has already got a great breakthrough to some extent in this hot area.Based on geological background,lithofacies features,oil-generating conditions and reservoir characteristics,this paper compared the mechanism of petroleum accumulation and the rule of enrichment of the tight oil in Bakken Formation with that in the Chang 7 Member of Yanchang Formation.The results show that the two formations are quite similar in geological background,disposition of source and reservoir rock,charac-teristics of source rock and reservoir.The only difference is that the average thickness of the shale in Yanchang Formation is thicker than that in the Bakken Formation.The comparison results indicate that the Yanchang For-mation in Ordos Basin has a good exploration prospect.关键词
