摘要
高强度油井管的强韧性不匹配是深部地层油气资源勘探开发面临的难题。通过性能参数比较,综述了高强高韧油井管的品种及在研究、生产中存在的问题和强韧化方法。在高端油井管产品技术领域,中国和发达国家之间仍然存在一定的差距,应加快高强高韧油井管国产化进程。
The mismatch of strength and toughness of high strength OCTG is a dilemma for exploration and development in deep oil and gasfields. By performance parameter comparison, the grades, critical issues and strengthening-toughening for the high strength and high toughnessOCTG were discussed. There is still a technology gap between China and developed countries in the field of high-end OCTG product,and the localization process of high strength and high toughness OCTG should be accelerated.
