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. Through the study of the geochemical characteristics of saturated hydrocarbons in the crude oil and hydrocarbon source rocks in the Baijai Sea uplift and its adjacent areas in the Junggar Basin, the organic composition of the source rocks, hydrocarbon generation environments, evolutionary stages and the migration patterns of crude oil It is pointed out that the Paleo-Lower Jurassic, especially the Sangonghe Formation, mudstone series in the Baijiahai and Fukang sags are the main source rocks of the Cainan oil reservoir, which provides a scientific basis for further exploration in the future.
