摘要
综合运用钻井、岩心化验分析、测井等资料,对高升探区的沉积体系进行了分析,并对沉积相及沉积微相进行划分。结果认为:该区下第三系属于断陷湖盆沉积体系,主要发育有扇三角洲沉积、深湖浊流沉积和粒屑灰岩沉积,早期还发育冲积扇沉积;各时期形成的砂岩和粒屑灰岩储集体,为油气储集提供了有利的场所。其研究成果对该区的进一步勘探开发提供了依据。
This paper analyzes the sedimentary system and gives a division to sedimentary facies in Caosheng exploration area by using drilling , core analysis and logging data. The result indicates that the Palaeogene of this area belongs to faulted lake - basin sedimentary system. Mainly developed are fan - delta, deep lake turbidite and calcirudite deposit, and also alluvial fan deposit in early period. Sandstone and calcimdite reservoirs formed in various stages provided favorable places for oil and gas accumulation. This study provides basis for further exploration and development in this area.
