准噶尔盆地夏盐南部侏罗系三工河组沉积特征及其控制因素
|
摘要
利用岩性、测井曲线、地震反射特征以及储层反演,揭示了夏盐南部下侏罗统三工河组各砂组的沉积相类型主要为湖泊、扇三角洲和重力流;物源主要来自研究区北部和东部两个方向;研究区东部发育扇三角洲前缘,中西部地区发育重力流;其中,三工河组二段上部和三工河组三段半深湖相对发育,三工河组一段上部重力流最发育;三工河组二段下部滨浅湖相对发育。整体上水体由深变浅再变深与该时期气候演化耦合,且气候是研究区沉积演化的主控因素。
Based on lithology,well logs,seismic reflections and reservoir inversion,it is revealed that the sedimentary facies distribution of the lower Jurassic Sangonghe Formation in the southern Xiayan area of Junggar Basin is mainly lake,fan delta and gravity flow.The provenances are mainly in the north and in the east of the study area.The fan delta front is developed in the eastern part of the study area,and the gravity flow is developed in the central and western regions.The semi-deep lacustrine facies is relatively developed on the top of second member and third member of Sangonghe Formation.The gravity flow mostly occurred on the top of first member of Sangonghe Formation.The shore-shallow lake mainly developed at the bottom of second member of Sangonghe Formation.In general,the water depth variation is coupled with the climate evolution of the period,which was from deep to shallow to deep,and climate is the main controlling factor of the sedimentary evolution in the study area.
