Abstract: Research achievements on hot oil pipelines at home and abroad are analyzed and summarized, and relative technical issues existed in study of operation optimization on hot oil pipelines are concluded. The paper sets forth the research progress in operation optimization technology of hot oil pipelines, analyzes optimization model and algorithm under steady operation condition of the pipeline and summarizes research achievements in operation optimization technology of the pipelines as well as issues existed. It is proposed that research activity under unsteady state conditions, optimization algorithm and software development for hot oil pipelines should be carried out.
