根据我国原油的物理性质，为降低输送成本，石油储运界人士研究成功并大力推广原油长输管道常温输送工艺，取得了显著经济和社会效益。阐述该工艺包括采用物理化学的方法对原油实施改性的4项内涵。提出今后对该工艺技术的发展应列入战略研究的重点课题。 According to the physical properties of crude oil in our country, in order to reduce the transportation cost, the oil storage and transportation circles have successfully researched and promoted the transportation technology of crude oil long-distance pipeline at room temperature, and achieved remarkable economic and social benefits. Explain the process includes the use of physical and chemical methods to modify the four connotations of crude oil. Put forward the future development of the technology should be included in the strategic research of key issues.
