Performance Comparison of Main Pipeline of X80 Deepwater Drilling Riser in Domestic and Overseas
摘要
Abstract
Along with the development of marine oil-gas exploration towards to the deep water field in China,the China localization development for well drilling riser is more and more important. The main pipeline of X80 grade marine well drilling riser with533.4 mm×25.4 mm produced in China was contrasted with that manufactured in overseas from several aspects,such as material composition,microstructure,tensile property,impact property,CTOD fracture toughness and geometric dimension control etc. The results showed that China manufacturer has preliminarily mastered the manufacturing technology of X80 deepwater drilling riser,but the stability of welding quality,geometric dimension precision control still need further improvement.关键词
