SEDIMENTARY FACIESES OF THE UPPER SHA 3 SUBMEMBER IN SHAHEJIE FORMATION IN YANGWUZHAI AREA OF RAOYANG SAG
饶阳凹陷杨武寨地区古近系沙河街组沙三上亚段的沉积相类型及平面分布特征研究缺乏,直接影响下一步勘探目标选择.利用测井、岩心等资料,对沙三上亚段沉积相进行了分析,划分出辫状河三角洲和湖泊2种沉积相类型.辫状河三角洲以辫状河三角洲前缘亚相沉积为主,包括水下分流河道、水下分流河道间、河口坝、席状砂等沉积微相；湖泊相以滨浅湖亚相发育为主,深湖—半深湖亚相发育面积较小.根据层序地层学研究结果,沙三上亚段划分为低位域、湖侵域和高位域3个体系域.低位域、高位域时…查看全部>>
For lack of the researches of the sedimentary facies type and planar distributary characteristics for the Sha 3 Upper Submember of Shahejie Formation of Eogene system in Yangwuzhai area in Raoyang Sag, the choice of further explorationa target is directly affected. Through virtue of the data of well logging, cores and so on, the sedimentary facies are analyzed and finally two kinds of types including braided river delta and lacustrine facies are identified. …查看全部>>
