Experiment Study of the Effect of Flow Improver on the Reducing Resistance of Oil-water Mixture Pipeline

摘要

Aimed at high water cut crude oil, adding new-type flow improver to oil-water mixture pipeline could obviously lower the mixture's viscosity to advance the phase transition point, and could greatly reduce the on-way resistance; meanwhile, ilow improver could reduce the cold start-up pressure, and the calculation formula of the cold start-up pressure gradient was built. Using the new-type flow improver to carry out low temperature transportation, the temperature of oil gathering decreased greatly. and economic benefit was obvious.
