【摘要】：在详细分析前人研究成果的基础上,运用高分辨率层序地层学方法,收集岩心、测井曲线、地震剖面等资料,开展层序地层和油层细分对比等工作,将扶杨油层共划分为39个小层。本论文以砂体展布特征、重矿物和地层倾角资料的统计分析为依据,紧密结合区域构造背景展开了朝长地区物源判识研究,认为研究区内扶杨油层主要受东南和西南两个物源方向影响。沉积环境与沉积相是控制砂岩储集体发育与分布的先天性地质因素,本文基于岩心、录井和测井、和分析化验等资料对研究区沉积相及其分布进行了精细分析,指出该区块主要发育曲流河和三角洲沉积。并在研究区识别出分流河道、水下分流河道、边滩、席状砂等8种沉积微相类型,建立岩心—测井相模式,对主力油层砂体分布进行了详细研究。
[Abstract]:On the basis of the detailed analysis of the previous research results, the high resolution sequence stratigraphy method is used to collect core, log curves, seismic profiles, and to carry out the work of sequence stratigraphy and reservoir subdivision and correlation. The Fuyang reservoir is divided into 39 sublayers. Based on the distribution characteristics of sand bodies, the statistical analysis of heavy mineral and stratigraphic dip data, and in close combination with the regional tectonic background, a study on the identification of source materials in Chaokang area has been carried out in this paper. It is considered that the Fuyang reservoir in the study area is mainly affected by two source directions: southeast and southwest. Sedimentary environment and sedimentary facies are the congenital geological factors controlling the development and distribution of sandstone reservoir. Based on the data of core, logging and logging, and analysis, the sedimentary facies and their distribution in the study area are analyzed in detail. It is pointed out that the meandering river and delta deposits are mainly developed in this block. Eight types of sedimentary microfacies, such as distributary channel, underwater distributary channel, edge beach and sheet sand, are identified in the study area. The core logging facies model is established and the distribution of the main reservoir sand body is studied in detail.
