PROPERTIES AND ALTERATION OF VISCOUS OIL IN THE NORTHWEST MARGIN OF THE JUNGGAR BASIN
-
摘要: 本文研究了准噶尔盆地西北缘稠油的物理性质和地球化学性质.通过与国内外稠油类比,发现该区稠油有其殊异的特性,这些特性反映了烃类经长距离运移的地质色层效应作用.同时,根据稠油这些特征,提出该区稠油的蚀变作用可分为生物降解作用、氧化作用、水洗作用和扩散作用等.Abstract: The physical and geochemical properties of viscous oil in the northwest margin ofJunggarBasin were studied in the paper.By correlating it with viscous oils home and abroad,it isfound that the viscous oil in this region is characterized by geochromatographic effects resulted from the long distance migration of hydrocarbons,Additionally,the alteration ofviscous oil would be divided into biodegradation,oxygenation,water washing and diffu-sion respectively.
