摘要

鉴于蓬莱19-3地区物源存在一定的分歧,通过对蓬莱19-3地区新近系砂岩碎屑轻矿物、重矿物、粒度分析、砂岩展布特征、地震资料及动态资料的分析认为该地区物源主要来自于东边。结合物源及藻类分析认为蓬莱19-3以西存在一定的水体,明下段表现出浅水三角洲窄河道绫罗分布的特征,而馆陶组以辫状三角洲平原为主。建议在油田地质油藏研究过程中考虑物源及沉积相,完善产液结构,从而改善油田开发效果。
There is different opinions about the source of Penglai 19-3 area and through the analysis of heavy mineral,light mineral,grain size analysis,distribution of sandrocks and seismic data in Neogene of Penglai 19-3 area,it is believed that the sedimentary source is mainly from the east.Considering the analysis of resource and algal,it is believed that large water body exists in this area.Guantao stage is of braided delta with narrow channels,while Minghua stage is mainly of shallow water facies.So it is suggested that oil filed geology and reservoir study should take sedimentary source and facies into consideration and perfect the structure of fluid production so that improve the effects of oilfield development.
