摘要
采用气相色谱、色谱-质谱、同位素、红外光谱等方法，分析了长北油田原油的来源、母质类型的成熟度的高低。研究结果表明．本区原油具有同源性，母质为陆相沉积腐殖型，原油生成于浅湖相弱还原环境中，热演化处于低成熟-成熟过程。
Using gas chromatography, gas chromatography-mass spectrometry, carbon isotopes and infrared spectrometry to analyze the source, type and the maturity of crude oils in the Changbei oilfield. It is indicated that the crude oils came from the same source and the source materials are of the terrestrial sedimentary humid type. The crude oils were produced in shallow lake and weakly reducing environments. Their thermal evolution proceeded from low mature to mature.
