Progress of Research and Development of Patented Technologies on Corrosion-Resistant Steels for Oil Country Tubular Goods

Abstract

Abstract: Based on published patented manufactured technologies of corrosion-resistant steels for oil country tubular goods ( OCTG) in the world from 1994, the characteristics of research and development of corrosion-resistant steels for OCTG at manufacturing enterprises and the chemical composition, key manufacturing technologies and properties of corrosion-resistant steels for OCTG including martensite, austenite, dual phase and complex phase stainless steels, low alloy steels and Cr alloy steels are summarized. The key points of research and development at OCTG manufacturing enterprises are development of the OCTG with low cost and corrosion resistance in various conditions.

Key words: Steel for Oil Country Tubular Goods, Corrosion Resistance, Patent, Research and Development

摘要： 根据1994年至今全世界公开的耐腐蚀油井管用钢专利技术,概述了耐腐蚀油井管用钢制造企业的研发特点,以及马氏体、奥氏体、双相、复合相不锈钢,低合金钢和Cr合金钢等耐腐蚀油井管用钢的化学成分,关键技术和性能。低成本、耐各种条件腐蚀的油井管开发是油井管生产企业的研发重点。
