| 摘 要： | 通过对海拉尔盆地乌东斜坡带南屯组一段油富集规律的分析,揭示了该区南一段油富集的主控因素。研究表明,乌东斜坡带南一段发育的优质烃源岩,为南一段油的富集提供了重要来源;南一段发育辫状河三角洲沉积体系,其中有利的沉积相带和砂体分布区控制着油的丰富程度;研究区从洼槽到断裂坡折带到缓坡带,总体表现为水—油—水的关系,控圈断裂的侧向封闭能力决定着圈闭的有效范围和油水边界。下一步南一段油的勘探和开发应以断圈封闭的油水界限内有利沉积相带和渗透性砂体区域为主要目标。 |

| Abstract: | The analysis on the features of oil enrichment law in first sector of Nantun group(NI) revealed the dominative factors on the NI reservoir in the Wudong slope zone in Hailar basin.Results showed that the excellent source rocks in the NI provided the main source for the oil enrichment in NI reservoir.The braided stream delta sedimentary system was developed in the NI reservoir,in which the favorable sedimentary facies zone and permeable sand body controlled the oil enrichment degree.In the study area,from the subsag to the fault slope break,then,to the gentle slope,it appears the relationship from water to oil to water.Lateral sealing abilities of the faults determine the oil/water interfaces and limits of the traps.The next oil exploration and development objective should be in the favorable sedimentary facies and sandstones within the boundaries limited by the sealed faults. |
