| 中文摘要:本文以江汉盆地江陵凹陷为例,利用钻井、测井、地震及分析化验等资料,通过对该凹陷构造演化与油气生成、运移与聚集、输导体系之间的控制作用研究,探讨构造演化与含油气系统的关系.指出江陵凹陷可以划分为一个完整的含油气系统,该系统形成于新沟咀组下段一荆河镇组沉积期,主要形成时期为古近纪荆河镇组沉积末期,保存期为新近纪一第四纪;总结了油气藏的形成特点,揭示油气藏形具有多层系同期成藏的规律,因此,江陵凹陷具有多套勘探层系,可以进行立体勘探,应加大原、次生油藏兼探的力度和步伐,扩大江陵凹陷的勘探成果. |

| Abstract:Through an investigation into the relationship of structure evolution to hydrocarbon generation,migration and accumulation as well as conduction system of Jiangling depression based on well drilling,logging and seismic data as well as test results,the authors studied the relationship between structure evolution and petroleum system of Jiangling depression and pointed out that there exists a whole petroleum system which was formed from Middle Jingsha Formation to Late Jinghezheng Formation(Middle Eocene to Late Pleistocene)and then entered into the preservation stage.This paper has summarized the formation characteristics of the reservoirs and revealed the regularity of contemporaneously formed reservoirs in different strata.It is thus held that the Jiangling depression has multiple exploration layers and can be explored with the aid of three-dimensional exploration strategy so as to improve exploration efficiency.The exploration for both original and secondary reservoirs should be speeded up to achieve more commercial discoveries. |
