准噶尔盆地陆西地区石炭—二叠系火山岩岩性岩相特征及其对储层的控制
Lithologic and lithofacies characteristics of the Carboniferous-Permian volcanic rocks and their control actions on the reservoirs in Luxi area,Junggar Basin
【摘要】 在分析准噶尔盆地陆西地区石炭—二叠系火山岩区域构造背景、火山活动规律的基础上,通过岩心观察、薄片鉴定、全岩分析、X射线衍射分析,综合测井、地震与重磁资料,划分了岩石、岩相类型,在"优势岩相"思路的指导下,建立了岩相模式,总结了岩相平面展布规律,研究了岩性、岩相对火山岩储集层发育的控制作用及有利储层分布,对火山岩油气藏的进一步勘探有更重要的指导意义。
【Abstract】 This paper analyzes the tectonic settings and volcanic activities in the Carboniferous-Permian volcanic rocks in Luxi area,Junggar Basin through core observation,thin section identification,bulk rock analysis and X-ray diffraction by using comprehensive logging,seismic and gravity and magnetic field data;classifies rocks and lithofacies;establishes lithofacies model as guided by the concept of "dominant lithofacies";summarizes the distribution pattern of the lithofacies;and studies the control action of lithology and lithofacies on the development of volcanic reservoirs and the distribution of favorable reservoirs.The results will be of guiding significance for further exploration in volcanic reservoirs.
【Key words】 lithologic and lithofacies characteristics; lithofacies model; reservoir characteristics; volcanic rock; Luxi area; Junggar Basin;
