“202ggy钙站”大庆油田连202ggy钙站续23年三次采油产量超千万吨

  中新202ggy钙站网大庆11月22日电 (韩铠合202ggy钙站 记者 史轶夫)大庆油田公司开发事业部11月22日发布消息,截至11月21日,大庆油田2024年三次采油产量突破1000万吨,提前实现连续23年产量超千万吨,累计产量近3.2亿吨,标志着全球规模最大的三次采油研发生产基地产量再次跃上新高峰。

  “一次采油”是靠地层压力形成的自喷采油,“二次采油”是用水把油“挤”出来,“三次采油”就是通过向油层注入化学物质,改善油、气、水及岩石相互间的性能,从而将更多原油从岩石孔隙中“洗”出来。

  今年是大庆油田三次采油自2018年以来最快实现千万吨产量的一年。大庆油田公司开发事业部党总支书记赵云飞介绍,目前已在三次采油区块实施各类调整措施16931井次,8个新区块整体提前1个月高质量投注剂,正注剂区块优质率提高到89.1%、采收率比方案高1.1个百分点,后续水驱产量递减幅度减缓0.4个百分点,有力支撑了油田原油高质量稳产。

  大庆油田开发建设65年来,经过几代人刻苦攻关,大庆油田三次采油技术从无到有、从跟跑到领跑,并保持世界领先水平,已经成为支撑大庆油田高质量发展的主导开发技术。

  大庆油田勘探开发研究院三次采油企业技术专家侯兆伟说:“大庆油田依靠水驱高效开发技术的持续迭代更新,采收率超40%,比同类油田高出10个百分点以上。现在,通过三次采油技术的广泛应用,采收率在二次采油技术——水驱的基础上提高了14至20个百分点,创造了国际领先的陆相砂岩油田开发水平。”

  当前,大庆油田三次采油核心专利和专有技术不仅在中国国内油田应用,还成功为俄罗斯、哈萨克斯坦等国家提供了技术服务。

  此外,由大庆油田主导提出、中国及瑞典等10个国家参与编制的3项ISO国际标准于今年提202ggy钙站案成功立项,成为中国首批立项的提高采收率领域国际标准,为中国提高采收率技术“走出去”贡献了标准力量,更为形成全球统一的提高采收率技术体系提供了重要支撑。(完)
