摘要
智能水驱提高采收率技术是一种有效的剩余油挖潜措施,智能水驱能够大幅度提高采收率而且经济效益好,并且该技术能够利用现有注采井网,减少投资,不需要大量化学剂和复杂的地面处理,是一项经济、环保、易操作、潜力巨大的油田开发新技术。通过对江苏油田梁垛区块进行四种无机盐驱油实验、注入水与产出水驱油效率实验、不同比例的注入水与产出水配比驱油实验、智能水驱油效率的研究,在现有的注水开发的基础上优化注入水的矿化度,从而提高原油采收率。
Smart water flooding enhanced oil recovery technology is an effective remaining oil tapping measure, smart water flooding can significantly improve oil recovery to obtain good economic return, and the technology can make use of the existing injection-production well pattern to reduce investment cost. The technology does not require a large number of chemical agents and complex ground handling process, so it is economic, environmentally friendly, easy to operate, and has great application potential in oil field development. In this paper, four kinds of inorganic salt flooding experiments in Liangtu block of Jiangsu oilfield were carried out as well as experiments on flooding efficiency of injected water and output water, experiments on proportioning ratio of injection water to output water in water flooding, study on the efficiency of smart water flooding. The degree of mineralization of injected water was optimized for enhancing oil recovery.
