【摘要】：南泥湾油区和大多数油田一样都采用了注水保持压力的开发方式,出现了油井含水上升快和高含水井,急需进行治理和研究。因此本文对南泥湾采油厂选择一个高含水区块进行注水开发效果分析的研究。本论文主要研究内容如下:1在油藏基础地质的基础上,利用已有的动静态资料,对油藏特征做出新的认识和评价;2进行油田开发动态分析;3对开发效果和现注水开发方案进行分析评价,找出影响油井含水快速上升的因素和油田开发效果的主要问题;4合理调整注采关系,确定相应的调整方案和治理措施,提高油田最终采收率。通过一系列的研究,油藏综合治理方案需要完善注采井网、调整注采对应关系、优化注水技术政策和严格控制注入水水质。高含水井的综合治理对策主要有:注水调整、周期注水、堵水调剖和线状注水。因此科学合理的评价注水开发效果,不仅对南泥湾高含水井的有效治理具有重要意义,更为进一步搞好油藏注水开发以及提高最终采收率具有重要的意义。同时,为类似南泥湾油田的其它油区的高效注水开发提供借鉴和示范作用。
[Abstract]:The Nanniwan oil area, like most oilfields, has adopted the development method of water injection maintenance pressure, and the oil wells have a rapid rise in water cut and a high water cut. Therefore, this paper studies the selection of a high water-cut block to analyze the effect of waterflooding development. The main contents of this paper are as follows: 1 on the basis of reservoir basic geology. Based on the existing static and static data, a new understanding and evaluation of reservoir characteristics are made. To find out the factors that affect the rapid rise of water cut in oil wells and the main problems of oilfield development effect: to rationally adjust the relationship between injection and production, to determine the corresponding adjustment scheme and treatment measures, and to improve the final oil recovery of the oil field. Through a series of studies, The comprehensive control plan of reservoir needs to perfect injection-production well pattern, adjust injection-production corresponding relation, optimize water injection technology policy and strictly control injected water quality. The comprehensive treatment countermeasures of high water cut well include: water injection adjustment, periodic water injection, etc. Therefore, scientific and reasonable evaluation of water injection development effect is not only of great significance to the effective treatment of high water cut wells in Nanniwan. It is of great significance to further improve the reservoir water injection development and to improve the final recovery. At the same time, it provides reference and demonstration for the development of high efficiency water injection in other oil areas similar to Nanniwan Oilfield.
