摘　　要：以塔河油田12区特稠油中的AD15、TK1225号油井原油作为研究对象,用扭矩式流变仪测定原油在不同温度下的粘度,用氧化铝柱层析法测定原油族组分及其含量,用傅立叶红外光谱法分析族组分中胶质和沥青质的主要官能团,分析原油中胶质和沥青质对原油流动性的影响。结果表明,胶质、沥青质在原油中起着主要的增稠作用,其结构对原油的流动性有明显的影响。This text selected pickup AD15 and TK1225 in the extra heavy oil of the 12th districts of Tahe oil field.The two sample were regarded as the research object.We use the method of alumina chromatography to determine the constituent,determine the viscosity of crude oil at different temperature with the torsion type theology appearance.The main functional group of colloid and asphaltene and its effect on fluidity of crude oil by FTIR.The result indicates,the colloid,asphaltene are playing main increasing thick function in the crude oil,its structure has obvious influence on flow ability of the crude oil.
