【摘要】：为了系统认识榆树林油田尚9区块扶杨油层主力砂体发育及分布特征,本文利用钻井资料、测井资料、三维地震资料以及开发试油资料,首先通过地层精细划分对比和井震结合的方法划分了研究区扶杨油层沉积时间单元,建立了成因单砂体级的地层格架;其次在取心井相分析及测井微相模式建立等基础上,勾绘了各沉积时间单元的平面沉积微相,并分析了其垂向沉积相演化特征;最后,通过构型参数的精细选取,建立了研究区典型沉积单元FⅠ71砂体内部建筑结构,并利用沉积微相控的多参数综合法,勾绘了研究区9各重点层位储层流动单元。认为研究区扶杨油层可划分为75个沉积单元;发育三角洲分流平原亚相和前缘亚相,分流平原亚相主要分为河道主体、分流河道、废弃河道、一类溢岸砂、二类溢岸砂及分流间湾微相,三角洲前缘亚相主要分为水下分流河道、席状砂主体、席状砂、席内缘、席外缘及水下分流间微相;划分出A、B、C、D、E1、E2等6类流动单元,其中A类是储集性能最好的流动单元。通过本文的研究为研究区扶杨油层主力油层后续的开发部署和剩余油挖潜提供可靠依据。
[Abstract]:In order to systematically understand the development and distribution characteristics of the main sand bodies of Fuyang reservoir in Shang9 block of Yushulin Oilfield, this paper uses drilling data, logging data, 3D seismic data and development test data. Firstly, the sedimentary time unit of Fuyang oil layer in the study area is divided by the method of fine stratigraphic division and correlation with well shock, and the stratigraphic framework of single sand body level is established, secondly, on the basis of coring well facies analysis and logging microfacies model, etc. The planar sedimentary microfacies of each sedimentary time unit are plotted, and the evolution characteristics of vertical sedimentary facies are analyzed. Finally, through the fine selection of configuration parameters, the building structure of the typical sedimentary unit F 鈪，
