摘要
本文通过岩心观察、薄片鉴定、测井资料、三维地震资料的综合分析,对徐家围子断陷营成组火山岩岩相进行了细致的划分。本区主要发育熔岩、火山碎屑岩、沉火山碎屑岩三大类火山岩,本区可以识别的火山岩相为4种岩相8种亚相,不同火山岩岩性岩相发育不同的储层,因此,研究火山岩岩性岩相对油气勘探有至关重要的意义。
Based on synthesize analysis of core observation, thin sections identification and integration of well log and 3D seismic data,we conducted a detailed divided in Yingcheng Formation in Xujiaweizi Faulting. This area mainly develop lava,athrogenie rock and sedimentary athrogenic rock 3 kinds of volcanic rock,four kinds of volcanic lithofacies and eight kinds of intrafacies are identified in this area. Different volcanic lithology and lithofacies develop different reservoir,so the analysis of volcanic lithofaeies is very important for oil and gas exploration.
