Description

technical field [0001] The invention relates to a deep-sea petroleum transportation pipeline, in particular to a high-temperature-resistant and corrosion-resistant deep-sea petroleum transportation pipeline inner lining material and a preparation method thereof. Background technique [0002] In my country's oil and gas resources, H 2 S / CO 2 The sour natural gas fields account for about 20% of the proven reserves. In recent years, the service environment of domestic oil fields has become increasingly harsh, with gradually rising water cut and temperature, and high content of Cl — , CO 2 、H 2 S and other corrosive media bring great risks to the application of steel pipes. In order to reduce the loss caused by corrosion, researchers use non-metallic pipes instead of steel pipes. At present, there are mainly steel skeleton plastic pipes, glass steel pipes, and plastic alloy composite pipes. Non-metallic pipelines can slow down the internal corrosion of pipelines when transp...
