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。 Triassic in Hongche region is one of the important oil and gas-rich belts in the northwestern margin of Junggar Basin. The study of sedimentary facies is the basis of favorable zone evaluation. Through the description and analysis of cores and log and seismic data, a variety of sedimentary facies types are identified in Hongche region, including alluvial fan, braided river, delta, Lakes and so on. The braided river developed during the deposition of the Lower Karamay Formation in Hongshanzui area is favorable facies belt of lithologic reservoirs.
