沈84-安12块沙三段高凝油油藏储层特征研究

沈84-安12块沙三段高凝油油藏具有储层认识不清、油藏开发动用难度大的问题,开展储层特征研究,对于该类油藏转驱开发、提高效益化具有重要意义。针对该类油藏的储层特点,从储层岩石学特征、储层储集空间类型、储层物性等方面,系统分析了该区块的储层发育特征,并对其进行分类评价分析储层主控因素,为下一步区块转换开发方式,提高油藏采收率奠定基础。

Study on reservoir characteristics of high pour point oil reservoir in Sha 3 member of Shen 84-An 12 block

the high pour point oil reservoir in the third member of Shahejie formation of shen84-an12 block has the problems of unclear reservoir understanding and difficult reservoir development and utilization. It is of great significance to carry out the research on reservoir characteristics for the development of this kind of reservoir and to improve the efficiency. According to the reservoir characteristics of this kind of reservoir, this paper systematically analyzes the reservoir development characteristics of this block from the aspects of reservoir petrology characteristics, reservoir space type, reservoir physical properties, etc.,and makes classification evaluation and analysis of the main control factors of the reservoir, so as to lay a foundation for the next block to change the development mode and improve the recovery rate of the reservoir.
