摘　　要：国内稠油分类标准于20世纪80年代末由刘文章教授提出并建立起来。该标准以原油粘度作为主要分类指标,以原油密度作为辅助分类指标。准噶尔盆地浅层稠油开发实践表明,不同类型储层的稠油油藏开发方式及效果差异很大,除原油粘度外,储层岩性是影响稠油开发效果的另一重要因素。在国内稠油分类标准的基础上,根据新疆准噶尔盆地西北缘油区4个油田22个稠油主力层块分析结果,采用地面脱气原油粘度为主要指标,储层岩性作为辅助指标,结合开发难易程度,将准噶尔盆地浅层稠油分为3大类4亚类12级,以期为今后的稠油开发研究和油藏管理提供借鉴。The internal classification standard of heavy oil was proposed and established by Professor Liu Wenzhang in the late 1980s.The standard used the heavy oil viscosity as the classification index and its density as the auxiliary classification index.The exploitation practice of the shallow reservoirs in Xinjiang Oilfield shows that different types of heavy oil reservoirs have different development ways and effect,the reservoir lithology is another important factor influencing the development effect.Based on the internal heavy oil classification standard and according to the analysis results of 22 heavy oil blocks in 4 oilfields in northwest of Xinjiang Oilfield,surface degassing oil viscosity is used as main index,reservoir lithology is used as second index,in combination with difficulty degree of its development,shallow heavy oil in Xinjiang Oilfield is classified into,and 12 grades of 4 subclasses of 3 classes,for the purpose of providing some references for heavy oil development and reservoir management in the future.
