Application and performance analysis of carbon fibber composites in deep sea oil and gas development

Abstract

With the drastic reduction of China's land and shallow sea oil and natural gas resources, offshore oil and gas field exploration has gradually developed into the deep sea of 1500-300 m. Traditional steel materials are no longer applicable, and fibre composite materials have become the most exploited in subsea oilfields. One of the good materials is widely used in all aspects of deep-sea oil field equipment, providing a reliable guarantee for the development of deep-sea oil and gas fields. Based on this research background, the paper discusses the characteristics of carbon fibre composite materials (light weight, high specific strength, high specific modulus, fatigue resistance, corrosion resistance, and small thermal expansion coefficient), and discusses its application in the field of subsea oilfields.
