摘要
为了探索碳酸盐岩油藏后期开发方案,进行注氮气提高采收率试验。本文介绍了用DDL-Ⅲ生产测井为注氮气前的密封性评价测井和注氮气后的油气、油水界面监测提供深度标准。在雁翎油田见到了较好的效果。
In order to find out a better late-time development plan for carbonate reservoirs, nitrogen injection experiment is conducted for improving recovery ratio. This paper elaborates on cement bond evaluation with DDL-Ⅲ system, and oil-water and gas-oil contacts monitor before and after nitrogen injection. Satisfactory results have been obtained in Yanlin Oilfield.
