| 摘要: |
| 万利特凹陷是蒙古国东戈壁盆地的一个规模较大的凹陷,此前,因勘探程度低,凹陷内部的地层层序和构造层不清楚,含油气远景不被看好。通过近期在凹陷内的一口深探钻井,对该凹陷的石油地质情况有了新的认识:万利特凹陷与二连盆地、宗巴音凹陷具有相同的地层层序,凹陷的主体沉积为下白垩统陆相沉积,与邻近的宗巴音凹陷一样,具有较好的含油气远景。 |

| Abstract: |
| The Unegt depression is a larger depression in the Dornogobi Basin,Mongolia.The depression has long been less prospective for the oil deposits because the stratigraphic and structural sequences are less studied in this region.New results of research in this study show that like the adjacent Zuunbayan depression and Eren Basin,the main part of the Unegt depression consist of the Lower Cretaceous continental deposits,and thus may be of good oil potential. |
