摘要
Abstract
Complex geological structures and various sedimentary facies are typical characteristics of the 3rd-1st members of Shahejie Formation in Zhuangxi Area,Zhanhua Sag.Based on observations and descriptions of cores from 17 wells in combination with seismic data and logging data,this paper systematically studies the sedimentary characteristics of fan deltas and turbidite fans and bar in these members of Shahejie Formation in the region.This study mapped and analysed the sedimentary facies distribution of different stratigraphic section in the Zhuangxi area based on the research of sedimentary facies and the single factor analysis with multifactor comprehensive mapping method.The single factors include sandstone thickness,sandstone strata thickness ratio,carbonate thickness and biological limestone percentage.The results show that fan deltas dominate the edge of the lake basin,close to Changdi fault of the 3rd member of Shahejie Formation.Turbidite fan dominates the declining of growth fault in the lake-basin center.While fan deltas exist in the edge of lake basin,next to Changdi fault in the 2nd member of Shahejie Formation.Sandy beach and life-form shoal are developed in the far northwest corner and around the Zhuangxi Buried Hill.Life-form shoal and lacustrine carbonate depositions are the main sedimentary facies in the 1st member of Shahejie Formation,while mudstone and oil shale deposit is found in the lake basin center.关键词
