摘　　要：选取胜利油田某区块的含蜡原油,对其组成进行了测定和分析,考察了原油中的矿化度、固体颗粒含量以及pH值等条件对原油析蜡点的影响。研究表明:矿化度的提高和固体颗粒的加入分别使得原油析蜡点升高了3.2℃和4.2℃;酸性条件使得原油的析蜡点升高了0.5℃;碱性条件使得原油的析蜡点下降了1.1℃。The waxy crude from a block of Shengli Oilfield was selected. Its composition was measured and analyzed to inspect the effect of salinity of crude oil, solids content, as well as conditions such as pH value on the drop out point of crude oil. Study shows that the high salinity and introduction of solid particle causes the drop out point of crude oil increasing 3.1℃ and 4.2℃ respectively, acidic condition increase 0.5℃ of the drop out point of crude oil . Alkaline decreases 1.1℃ of the drop out point of crude oil .
