川西地区龙门山前带侏罗系物源与沉积体系演化
|
摘要
前陆盆地山前带近源体系是近几年沉积学领域的研究热点与难点。侏罗系沉积期,川西地区龙门山前带发育了一套近源粗粒沉积体系。笔者充分利用全区覆盖的三维连片地震数据、测录井、岩心及野外露头资料,分析了不同时期物源特征和沉积体系演化过程。研究结果表明:(1)侏罗系沉积期,龙门山前带共发育来自短轴和近长轴2个方向的5套物源体系;(2)下侏罗统主要发育冲积扇-曲流河三角洲-滨浅湖-半深湖沉积体系,中、上侏罗统主要发育冲积扇-辫状河三角洲-滨浅湖沉积体系;(3)龙门山前带可以划分3种沉积模式,分别为早侏罗世、中侏罗世和晚侏罗世沉积模式。通过研究,不仅能够为龙门山前带侏罗系致密砂岩气藏的勘探提供理论依据和数据支撑,而且可以完善对近源冲积体系粗粒储层的认识。
Proximal sedimentary system in foothill belt of foreland basin has become a hot and hard topic in sedimentology in recent years. During the Jurassic depositional period,a set of proximalcoarse-grained sedimentary systemwas developed in the foothill belt of Longmen Mountain in the western Sichuan Basin. We analyzed the provenance features and sedimentary system evolution in different periods using an integrated dataset of seismic,well logging,core and outcrop data. The results show that:( 1) during the Jurassic,there were 5 provenances in the minor axis and near-major axis directions in the foothill belt of Longmen Mountain;( 2) in the Early Jurassic,alluvial fan-meandering river delta-shore-shallow lakesemi-deep lake system dominated this area,while in the Middle and Late Jurassic,alluvial fan-braided river delta-shoreshallow lake system were developed well here;( 3) three types of sedimentary models can be identified in the foothill belt of Longmen Mountain,namely the Early,Middle,and Late Jurassic sedimentary models. This study canprovide theoretical guidance and data support for the exploration of the tight sand gas reservoirs in the foothill belt of Longmen Mountain,and deepen our understanding of the proximal coarse-grained alluvial reservoirs.
