Experimental study on wettability of crude oil on the surface of plastic alloy pipe in an oilfield field

Non-metallic pipe is widely used in oilfield development in recent years because of its excellent corrosion resistance. In this paper, the wetting properties of the plastic alloy tube surface based on the contact angle of crude oil in some oil fields in Xinjiang Oilfield were experimentally studied. The wettability of the plastic alloy tube surface and its influence on the flow resistance were discussed. The wettability of metal surfaces was compared. This experimental study is helpful for the oilfield to make reasonable pipe selection.
