【摘要】 通过对金湖凹陷王龙庄油田杨村断裂带附近的构造特征、岩石学特征、岩芯和测井等相关资料的分析,认为研究区戴南组发育一般的河流三角洲主要为三角洲前缘亚相,并识别出了水下分流河道、河口坝、前缘砂席及分流河道间等4种微相。根据河道沉积在地震剖面上的反射特征和地震属性特征,采用优化的均方根振幅属性进行地震属性分析,并将岩芯-测井-地震属性相结合,识别了砂体的发育位置,精细控制了沉积微相的发育范围,提高了沉积微相平面图的精度,对研究区生产和实践工作具有重要意义。更多还原

【Abstract】 It is considered that the Dainan formation in the study area is a typical river delta with frontal subfacies,by analyzing the tectonic characteristics,petrological characteristics,core and logging data of Yangcun fault zone in the Wanglongzhuang oilfield in the Jinhu Sag.And four types of microfacies are identified,including distributary channels,mouth bar,sand sheet,and interdistributary bay,respectively.According to the reflection characteristics and seismic attribute of the channel sediments on the seismic section,the development position of the sand body and the sedimentary microfacies are identified by optimizing root mean square for seismic attribute analysis and using the combination of core-logging-seismic attributes.It improves the accuracy of the sedimentary microfacies plan and is of great significance for the oil and gas exploration and development work in the study area.更多还原
