摘要

应用层序地层学方法,通过不整合面、地震反射特征、测井等识别标志将厄瓜多尔Oriente盆地南部区块Napo组划分为5个三级层序,以地层叠置样式、岩性、岩相的变化细分出陆架边缘、海侵和高位体系域。在等时层序地层格架下,对Oriente盆地南部区块的油气地质条件综合分析,认为南部区块烃源条件较好、储集条件优越、生储盖组合有利,具有较大的勘探潜力,并指出Wanke、Horm、Horm-sur和Shripuno地区为南部区块最有利的含油气区带。
With the application of sequence stratigraphy method and based on the identification marks,such as unconformity,seismic reflection features and logging,Napo Formation in south block of Oriente basin is divided into 5 3rd order sequences.Shelf margin system,transgressive system and highstand system are subdivided according to stacking patterns of stratigraphy,and changes of lithology and facies.Under isochronal lithologic sequence,the hydrocarbon geologic characteristics of the south block in Oriente basin is analyzed comprehensively.According to the analysis,the south block has great exploration potential with better hydrocarbon source conditions,accumulation conditions and good generation-accumulation-seal assemblage,and Wanke,Horm,Horm-sur and Shripuno are the most favorable hydrocarbon bearing zones in this block.
