摘要
对塔里木油、哈国油和北疆油以不同比例混合后进行凝点测试,分析不同热处理温度与相同热处理温度下不同加剂量对油品凝点的影响,得到不同混油比例热处理温度及加剂量对油品凝点的影响规律,即重复热处理温度需高于40℃,加剂量控制在25mg/kg。基于实验室研究结果,在西部原油管道输送混合原油的过程中,沿线取样进行凝点测试,获得不加剂和加剂混合原油经沿线复杂热历史和剪切历史作用后凝点的变化情况,由此得出:首站一站启炉即可保证管道的安全运行,同时可结合管道特点制定安全、经济的运行方案。(表6,参6)
This paper carries out freezing point test for Tarim Oil, Kazakhstan Oil and North Xingjiang Oil mixed in different proportions, and analyzes the impact of different additive volumes on oil freezing point at different heat treatment temperatures and the same heat treatment temperature, and obtaines the influence law of different mixing proportions, heat treatment temperature and additive adding volume on the freezing point, i.e. repeating heat treatment temperature higher than 40 ℃, adding volume controlled at 25 mg/kg. Based on the results of laboratory studies, it carries out freezing point tests for the sample taken from the mixed crude oil in Western Crude Oil Pipeline, and obtaines the change situation of the freezing point of crude oil after acting by complex thermal history and shear history along the pipeline with additive and without additive. The results show that at present, just heater starting operation at the initial station alone can ensure safety operation of the pipeline, and that safe and economic operation schemes can be developed based on the characteristics of the pipeline. （6 Tables, 6 References）
