Recently, the spread of new technology development, such as centrifugal winding (CW) method and GPI (Global Oil & Gas Pipe Institute) screw joint advances, application performance and research results of the FRP pipe over the long term has been accumulated. This paper described that the strength design method of new oil well pipes, required to untapped deep oil wells derived from depletion of the existing oil and gas fields, depletion oil field of play EOR mining, more than 30 year of durability of new specifications, such as the withstanding pressure 100MPa, depth 7000m, heat-resistant 250 ℃, pH2 level of corrosion resistant, was clarified.
