New progress in relevant technology research of oil & gas storage and transportation in China

The new progress in relevant technology research of oil & gas storage and transportation in China is systematically categorized, and some hotspots in the research needed to be more concerned are presented. In pipeline integrity and failure control technologies, the author emphasizes the conception of failure control philosophy and the necessity in combining the conception with the integrity management. In hot oil flow assurance technology, the achievements in wax deposit, rheologic behavior of crude oil and shut-down/restart-up of pipeline are given. The research progress in the thermal factors and simulation results are provided for alternating transportaton of hot and cold crude oil. In multiphase blending transportation research, results in numerical simulation on different multiphase system are described. In the facet of controlling contaminatied volume of products oil in batch transportation, the results obtained in the contaminated volume cut method, mixed mass fraction model of contaminated volume and in-line tracing of contaminated interface are introduced in detail. For corrosion control technology, numerical simulation of CP system, the stray current corrosion and flowing of oil with water are revealed. In the aspect of chemical additive technology, the composited nano material, DRA both for oil and natural gas are summarized.
