南堡凹陷高柳构造带馆陶组辫状河沉积特征研究

本文对冀东油田南堡凹陷高尚堡-柳赞构造带馆陶组储层进行整体分析,运用层序地层学观点建立层序格架,然后在层序格架的控制下划分出河道、溢岸及河道间亚相。进而通过岩心观察,测井相分析以及对岩心取样进行化学分析,细化了馆陶组沉积相,划分出河道、废弃河道、心滩、决口扇等沉积微相。分析了沉积相对油气运移聚集成藏的决定性作用,有力地影响了冀东油田陆上乃至滩海的勘探进程。

In this paper, Jidong Oilfield NANPU depression Gaoshangpu--Liu zan Guantao Formation reservoir structure with an overall analysis, the use of point of view of sequence stratigraphy to establish sequence framework, and then in the framework sequence under the control of the division of the river, overflow between the river shore and subfacies. And then through the core observation, analysis and logging of core samples for chemical analysis, refinement of the Guantao Formation sedimentary facies, delineation of the river, abandoned channels, cardiac Beach, crevasse splay, such as sedimentary microfacies. Analysis of the relative sediment accumulation of oil and gas migration and accumulation of the decisive role, the impact of a strong land Jidong oil field exploration and even the process of the sea beach.
