滴西五彩湾地区石炭系火山岩岩相特征研究
The Lithofacies of Carboniferous Volcanic Rocks in Dixi Wucaiwan Area
摘要
Abstract
The complex volcanic rock types of carboniferous volcanic reservoir in Dixi Wucaiwan area,Junggar Basin have made further research on the volcanic rock lithology and lithofacies distribution characteristics difficult. Based on the core observation,thin section identification,logging,well logging data,and scanning electron microscopy(SEM),the responses of well logging were analyzed. The methods of lithology identification for volcanic rock were established. Furthermore,by analyzing the features of single well facies of 5 typical wells and section phase,the lithology and lithofacies distribution char-acteristics were studied. The results revealed that the north of study area is mainly tuff and sand-mudstone intermingled with intermediate volcanic rocks,basic volcanic rocks and volcanic breccia. What develops in the central part are tuff,intermediate volcanic rocks,tuffaceous sand,with crumb acidic intrusive rocks,acidic volcanic rocks and volcanic breccia. In the south-ern part,sand-mudstone and tuff are distributed ,with tuffaceous sand mudstone,basic volcanic rocks,crumby intermediate volcanic rocks and volcanic breccia. Due to the different reservoir performance of different volcanic facies,the research on the plane distribution features is of positive significance to oil and gas exploration.关键词
