【摘要】 红车地区三叠系是准噶尔盆地西北缘重要的油气富集带之一。沉积相的研究是有利区带评价的基础,通过岩心描述和分析,并结合测井、地震等资料,在红车地区识别出多种沉积相类型,主要包括冲积扇、辫状河、三角洲、湖泊等。红山嘴地区下克拉玛依亚组沉积时期发育的辫状河沉积为岩性油气藏有利相带。更多还原

【Abstract】 The Triassic in Hongshanzui-Chepaizi area is one of the important petroleum enrichment zones in northwestern margin of Junggar basin.The favorable exploration play assessment is primarily based on the studies of the sedimentary facies of the Triassic.This study identifies multiple sedimentary facies types in this area through core description and analysis,integrated with the log information and seismic data,including alluvial fan,braided river,delta,lake,etc.The braided river deposit in Lower Karamay formation in Hongshanzui area is the favorable facies belt for lithologic reservoir exploration.更多还原
