Abstract: This paper introduces the site experiment on the oil pipeline running with DRA for LinPu Oil Pipeline to verify the feasibility of oil pipeline running with DRA after oil throughput increasing and to determine the relationship between the injection volume of DRA and oil throughput (Reynolds Number). The experiment results show that the operation pressure lowers greatly after different concentration DRA injects, which increases the safety factor of pipeline operation and provides the technological base on the DRA's application for LinPu Oil Pipeline.
