| 摘 要： | 为搞清塔中地区中上奥陶统地质异常体属性及含油气特征,通过对异常体地球物理特征、沉积环境、层序特征分析及与已钻探证实的异常体对比等方法,初步认为异常体可能是生物礁、砂岩透镜体、海底浊积扇、火成岩体等,并认为异常体圈闭是油气聚集的有利场所,是塔中地区具有较大勘探潜力的前景区。

| Abstract: | Through comprehensive researches such as geophysical characters of the anomalous body,sedimentary environment,the characters of the sequences and correlation with other anomalous bodies which have been verified by drilling, studying the attribution and oil-and-gas-bearing character of geologic anomalous bodies of Middle-Upper Ordovician System in Tazhong Area.Preliminary conclusion is drew that anomalous bodies may be reefs,sandstone lenses,submarine turbidite fans or igneous rocks,etc..And the traps of the anomalous bodies are the favorable location for hydrocarbon accumulation,and should be the prospects of great exploration potential. |

| Keywords: | Tazhong Area anomalous body reef igneous rock sandstone lens turbidite fan |
