准噶尔盆地风城地区稠油特征及其成因探讨

Heavy oil characteristics and origin discussion in Fengcheng of Junggar Basin

对准噶尔盆地风城地区稠油物性特征及地球化学特征分析研究认为,该区稠油具有粘度高、密度大、胶质含量高等特征,原油物性随着埋藏深度的增加逐渐变好,侏罗系八道湾组原油的物性好于侏罗系齐古组。从生物降解作用、氧化作用、水洗作用等次生变化作用对该区稠油成因进行了探讨,对该区进行下一步勘探开发具有一定的指导意义。

Analytical study of the physical and geochemical characteristics of the heavy oil in Fengcheng area of Junggar Basin shows that the heavy oil in this area has high viscosity,high density and high colloid content.The physical property of crude oil becomes better as depth increases.The physical property of Jurassic Badaowan formation is better than Qigu formation.The origin of the heavy oil in this area is discussed in respects of biodegradation,oxidation and water washing effect.This may guide further exploration and development in this area.
