| 摘 要： | M8构造位于迈陈凹陷东部陆上部分,详细剖析该构造的油气藏特征对认识迈陈凹陷石油地质条件及指导下步勘探具有重要意义。该构造是受M3断层控制的一个含油断鼻构造,通过对该构造生、储、盖层及油气运聚条件的分析,认为油源为流沙港组烃源岩;烃源岩整体大量生排油气应在中新世以后;流二段及流三段上部的暗色泥岩与流三段砂岩形成较稳定的下储上盖的组合;圈闭具有形成早、继承发育的特点。综合分析及结合邻区油气藏的特点认为,M8块油气藏应为主要受断层控制的层状构造油气藏,进而总结出了迈陈凹陷东部的成藏模式。

| Abstract: | M8 structure is located in the eastern part of Maichen Depression.It's very important to analyses the character of this structure in detail for the purpose of guiding the next prospect work and understanding the petroleum geological condition of this depression.This structure is an oil-bearing structure which is controlled by M3 fault.Integrative analysis shows that the source rock is Liushagang formation,petroleum generated and blew out mainly after the Miocene Epoch.The mudstone of E2l2 and sandstone of E2l3 form the main association of reservoir and capping bed.Integrative analysis and comparison with the nearby area show that M8 structure was a layered reservoir controlled by fault.Based on this analysis,the reservoir pattern is summarized in this paper. |
