中文摘要：

为解决福山凹陷中特低渗透储量比例大、注水开发矛盾突出的问题，利用岩芯、测井、录井等资料，探讨花场地区流一段储层的岩石类型、构造特征，分析储层的岩相特征，明确储层的沉积环境。利用测井曲线和岩屑描述建立沉积微相的测井相模式，探究砂体的分布规律。结果表明：花场北部流一段储层发育两点物源，主要发育辫状河三角洲前缘亚相沉积；微相类型包括水下分流河道、河口坝、席状砂等5种类型；流一段储层沉积的砂体以水下分流河道为主，砂体分布具有明显规律性和方向性，水下分流河道的砂体宽度较大，由南至北呈叶状展布。该研究可为福山凹陷进一步的勘探与开发提供一定的理论依据。

英文摘要：

To solve Fushan Depression with ultra -low permeability reserves proportion in water flooding problem, we try to use the core and logging data, including rock types and structural features of a flow of reservoir area. This article makes a petrographic analysis of reservoir sedimentary environment and clear reservoir. The author is using logging data in a sedimentary microfaeies logging facies model to investigate the distribution of sand bodies. The results show the fault block reservoirs in a braided fiver delta of front sub - facies. Micro facies are divided into subaqueous distributary channel, including mouth bar, sheet sand and other five types of sand body. A flow of reservoir in underwater distributary channel and sand body distribution will have the obvious regularity and direction of underwater distributary in large channel width. From south to north, it is of phyllodes distribution. The study can provide a theoretical reference for further exploration and evaluation of Fushan sag.
