摘要
通过岩心观察,结合测井、录井资料及相关测试资料综合分析,对正宁地区长6油层组沉积相进行了系统分析。结果表明,该区主要发育重力流-三角洲-湖泊沉积体系,识别出了砂质碎屑流沉积、浊积体、三角洲前缘、(半)深湖四种亚相。研究区仅西南角发育三角洲前缘亚相,其余地区发育大量的砂质碎屑流和浊流等重力流沉积和(半)深湖泥。
Through core observation, combined with logging data integrated analysis as well as lots of data analysis, Chang 6 reservoir sedimentary facies in Zhengning area were analyzed. The result shows that the study area mainly developed gravity flow-delta-lake deposit system. Four subfacies including sandy debris flow, turbidity current,delta-front and deep lake mud can be identified. Delta-front subfacies only developed in southwestern corner of the study area. Gravity flow including sandy debris flow and turbidity current and deeo lake mud develoned in remaininc, Darts of the study area.
