塔里木盆地巴楚组层序地层及沉积演化
|
摘要
为了揭示塔里木盆地巴楚组层序地层样式和沉积演化规律,运用沉积学原理和层序地层学原理,通过对录井、测井和地震资料的分析,建立了巴楚组层序地层格架并对沉积演化规律进行了研究.结果表明:巴楚组发育了SQb1和SQb2两个层序,每个层序均可划分出海侵体系域(TST)和高位体系域(HST),各层序的地层分布范围逐层扩展超覆.沉积环境主要为浅海、临滨、前滨、后滨、滨岸沙丘及碳酸盐浅滩,从巴楚组沉积早期至晚期持续存在陆源碎屑与内源沉积物混积的沉积特征,总体具有由早期陆源碎屑沉积体系为主向晚期碳酸盐岩台地占优势的相带演化趋势.陆表海的古地貌和总体海侵的背景控制了巴楚组层序发育和沉积演化.
In order to reveal the sequence stratigraphic pattern and sedimentary evolution of Bachu formation in Tarim basin based on the principle of sedimentary and sequence stratigraphy and analyses of mud logging,well logging and seismic data,the sequence stratigraphy frame of Bachu was established and the sedimentary evolution was studied.The results show that Bachu formation can be divided into two sequences:SQb1 and SQb2,both of which can be divided into transgression systems tract(TST) and highstand systems tract(HST).Stratigraphic distribution range of both sequences extends further layer by layer and individual sequence overlaps the former.The sedimentary environment includes mainly shallow sea,shoreface,foreshore,backshore,coastal dune and carbonate shoal.From early to late stage of Bachu formation deposition,terrigenous detritus mixed with authigenic deposition continuously.In the mass,sedimentary facies evolution tendency turned from major terrigenous detrital depositional system into major carbonate platform.The palaeogeomorphology of Epicontinental Sea and the background of general transgression controlled the sequence development and sedimentary evolution of Bachu formation.
