介绍了 ERW石油套管的发展现状及使用情况。通过对我国近年来卷板轧制、管材制造及管加工等技术水平综合分析 ,认为 ,在我国建造 ERW石油套管生产线是必要的、可行的。文章着重介绍了宝鸡石油钢管厂从美国 PMC公司引进的套管接箍生产线的工艺技术装备情况和该厂进行 ERW石油套管的研制开发、质量检测以及在各油田下井试验等方面情况。经过一系列性能指标的检测试验和油田实际应用 ,证明生产的 ERW表层套管、油层套管以及接箍均达到美国石油学会 API标准要求 ,可满足用户相应的技术要求。
The current situation and usage of ERW oil casing was introduced. Through the comprehensive analysis of the technology level of coil rolling, pipe manufacturing and pipe processing in recent years in our country, it is considered that it is necessary and feasible to build the ERW oil casing production line in our country. The paper mainly introduces the technology and equipment of the casing coupling production line introduced by PMC Company from Baoji Petroleum Pipe Plant and the research and development of the ERW oil casing, the quality inspection and the downhole test in each oilfield. After a series of performance tests and actual field application, it is proved that the produced ERW surface casing, reservoir casing and coupling have both met API standards of the American Petroleum Institute to meet the user’s corresponding technical requirements.
