| 摘要: |
| 成藏组合体的研究是地学领域的一大热点,笔者利用钻井、测井、地震及分析化验等资料,以输导系统为重点,通过对构成成藏组合体的地质要素、地质作用的时空配置研究,将江陵凹陷划分为一个完整的成藏组合体,指出该成藏组合体油气成藏发生于荆沙中期-荆河镇晚期(始新世中期-渐新世晚期),具有不同层位同期成藏的特征。江陵凹陷具有多套勘探层系,可以进行多层系立体勘探,提高勘探效益。 |

| Abstract: |
| The term play is in common use in oil exploration. An exploration play is a family of hydrocarbon pools and prospects within a specified area which share a common geological history and have a commonality of trapping mechanisms, whether determined by structure or facies. The exploration plays in the Jiangling depression are examined herein on the basis of spatio-temporal arrangement of geological elements and processes in combination with cores, well logs, seismic and chemical analytical data. The hydrocarbon accumulation occurred mostly in the middle part of the Jingsha Formation and the upper part of the Jinghezhen Formation (middle Eocene to late Pleistocene) as multiple exploration horizons, and thus may be explored with the aid of three-dimensional exploration strategy in order to improve the exploration efficiency. |
