准噶尔盆地彩南油田油源研究

Study on Oil Source in Cainan Oilfield, Junggar Basin

通过对准噶尔盆地白家海凸起及其邻区原油与烃源岩饱和烃地球化学特征的研究,取得了彩南原油及烃源岩有机质在生源构成、成烃环境、演化程度和原油运移模式四个方面的认识,指出白家海凸起和阜康凹陷中、下侏罗统尤其是三工河组泥质岩系是彩南油藏的主力烃源岩,为今后进一步勘探提供了科学依据.

On the basis of study on geochemical characteristics of saturated hydrocarbon of oil and source rock in Baijiahai arch and its adjacent area in Junggar basin, understandings about component of oil source, hydrocarbon-forming environment, evolutional degree and migration model of oil are obtained. It is pointed out that Middle and Lower Jurassic (especially argillaceous rock of Sangonghe formation) in Baijiahai arch and Fukang sag are major source rock in Cainan oilfield, and these provide scientific basis for further oil/gas exploration.
