Material Properties Standard of Marine Drilling Riser

With the development of deepwater oil and gas fields in china, the demand of high strength marine drilling riser augments gradually. All the riser depends on importing, so the technology of high strength riser must develop in order to sinicization. After investigation on national and foreign standards about marine riser, it was found that there was not material properties standard of marine drilling riser. This paper mainly studied and established material properties standard of marine drilling rise, combined with material test of X80 steel above 20in, and analysed existing standards. Finally the material performance index of X80 steel marine riser had been established, which pushed the localization process of high strength riser.
