| 摘 要： | 厄瓜多尔Oriente盆地南部区块Napo组处于海陆交互沉积环境,碎屑岩和灰岩频繁互层.通过分析钻井、测井等相标志,识别出研究区存在海岸平原、潮坪、陆棚和局限台地4种沉积相.通过联井和平面相演化分析,认为研究区为缓坡型混积陆棚边缘沉积相模式,这一相模式以发育广阔的潮坪和混积陆棚为典型特征.潮坪砂岩主要出现在各段的下部,陆棚相的水下浅滩砂岩和灰岩滩出现在各段中部.潮汐水道砂体是最好的储层,灰岩滩为差储层.Wanke,Hormiguero,Horm_sur和Kupi地区为勘探的有利目标区. |

| Abstract: | Napo Formation of south block in Oriente Basin of Oriente was in sea-land alternating deposits environment, clastic rocks and limestones alternated frequently. By analyzing facies marks of well drilling and logging,four sedimentary facies of coastal plain,tidal flat ,continental shelf and restricted platform were identified. Analysis of well-connecting and plane facies evolution shows that the facies model in the studied area is of gentle-slope diamictic continental shelf edge with extensive tidal flat and ... |
