摘要
目的研究东濮凹陷北部东营组不整合的类型及其对油气的输导、封隔、成藏作用。方法综合运用录井、取心、测井和地震资料,详细研究东濮凹陷古近系东营组顶不整合的类型,进而探讨每种类型的油气地质意义。结果从油气输导与成藏的角度,将研究区不整合划分为3种类型:侧向输导型、垂向泄漏型、及封隔型不整合。结论侧向输导型有利于东营组内油气侧向运移和聚集;封隔型不整合的大规模发育,阻止了东营组油气的垂向运移和泄漏,阻碍了其上更浅层的油气成藏,是馆陶组、明化镇组至今未发现大规模油气藏的主要原因之一。
Aim To study the unconformity types of Dongying Formation in the northern part of Dongpu sag,and their effect on transporting,isolating and accumulating for hydrocarbon.Methods Logging,coring and seismic data are compreheasively used to study,the unconformity type of Dongying Formation in the northern part of Dongpu Sag in detail,and its significance in petroleum geology is discussed.Results According to the study,in terms of hydrocarbon transporting and accumulation,the unconformity is classified into three types,which are lateral transporting,vertical leaking,and isolating model.Conclusion The lateral transporting unconformity has the help for the hydrocarbon migration and accumulation of the Dongying Formation;the isolating unconformity that develops in largescale resists the hydrocarbon′s vertical migration and leaking of Dongying Formation,and disturbs the hydrocarbon accumulation in the shallower strata on it,which is the main reason why the large scale hydrocarbon reservoirs have not been discovered in Guantao and Minghuazhen Formation nowadays.
