Chapter

Abstract

Pour point depression and drag reduction are two important issues in crude oil gathering and transportation to improve the flow conditions of crude oil in long-distance pipeline transportation. Pour point depression transportation of crude oil refers to the transportation of crude oil treated by pour point depression methods. In this chapter, main ways for the depression of pour points including physical methods, chemical methods, and chemical–physical methods are introduced. Drag reduction transportation of crude oil refers to the transportation of crude oil in turbulent flow state added with drag reducing agent. Factors affecting the drag reduction effect of drag reducing agent including the property of crude oil, the structure of drag reducing agent, and the conditions of pipeline transportation are introduced.
