| 摘 要： | 进一步了解王古1潜山的构造特征及成藏条件,利用渤海湾盆地济阳坳陷东营凹陷王家岗地区的大量三维地震剖面和一些钻井资料,并结合东营凹陷南坡缓坡带区域构造背景及成藏条件分析认为,王古1潜山初始发育于印支期,后经燕山期拉张断陷,切割为断块并抬升,最后于燕山期定型,为典型的缓坡盆倾残丘潜山。该潜山被NW向和NE向断裂切割,潜山高部位侵蚀风化严重,上覆孔店组盖层及沙河街组烃源岩,油气通过断层和不整合面运移至潜山顶部形成侵蚀残丘型油气藏。 |

| Abstract: | This paper mainly analyzes 3D seismic profiles and logging data for the Wangjiagang structural belt in the Dongying sag of the Jiyang depression,the Bohai Gulf basin.Combined with regional tectonic setting and reservoir-forming conditions,we propose that the Wanggu 1 buried hill developed initially during the Indosinian period.Then,the faulted block formed and uplifted during the Yanshanian extension and depression.The present-day geometry was produced in the Yanshanian period.The Wanggu 1 buried hill is a typical basindipping residual-hill in the gentle southern slope of the Dongying sag.The buried hill was cut by two fault sets,one NW-striking and the other NE-striking. Fractures,solution cavities and pores developed well in the structural culmination.The Shahejie Formation is the hydrocarbon source rock and the Kongdian Formation is the regional cap rock.The oil and gas migrated along the fault and unconformity surfaces into the crest of the buried hill and accumulated to form the erosional residual-hill reservoir. |
| Keywords: | Dongying Sag gentle slope belt buried hill basin-dipping faults reservoir forming conditions |
