由于胜利油田重质稠油的开发，使其原油日趋重质化、劣质化，给胜利炼油厂的生产带来很大的影响。原油的酸值、硫、钙及重金属含量均有增加，为了适应原油的变化，胜利炼油厂对装置和设备进行了改造，实施了相应的对策及措施，取得了较好的效益。 Due to the development of heavy heavy oil in Shengli Oilfield, its crude oil has become more and more heavy and poorly quality, which greatly affects the production of Shengli Refinery. In order to adapt to the change of crude oil, Shengli Refinery has reformed the plant and equipment, implemented the corresponding countermeasures and measures, and achieved good benefits.
