In recent years, non-metallic pipes have been widely used in oilfield development due to their excellent corrosion resistance. In this paper, the wettability of flexible composite pipe and plastic alloy pipe surface was studied for some crude oil in Xinjiang oilfield. The wettability of the surface of the flexible composite pipe and the surface of the plastic alloy pipe and its influence on the flow resistance were discussed, and the wettability of the crude oil on the metal surface was compared. This experimental study has certain guiding significance for the judgment of pressure drop of crude oil conveyed by flexible composite pipe and plastic alloy pipe.
