摘　　要：运用色谱、质谱和碳同位素等分析技术对准噶尔盆地霍尔果斯油气田进行油气特征和油气源对比分析认为,该油气田原油来源于白垩系烃源岩,天然气来源于侏罗系煤系烃源岩。利用干酪根裂解气动力学和同位素动力学对霍尔果斯油气田生气史和碳同位素演化特征进行了模拟。模拟结果表明,该油气田的天然气不是白垩系原油裂解形成的,而是源于侏罗系煤系烃源岩干酪根裂解形成的,烃源岩大量生气开始于12 Ma或10 Ma左右,天然气成藏时期约为6 Ma。研究结果对准噶尔盆地南缘天然气勘探具有重要的指导意义。Oil and gas characteristics,oil/gas and source rock correlation are analyzed for Huo' erguosi oil and gas field of Junggar Basin by using chromatograph,mass spectrum and carbon isotope analysis techniques.It is believed that the crude oil originates from the Cretaceous source rock,and the natural gas originates from the Ju- rassic coal- measure source rock.Gas generation history and carbon isotope evolution are simulated by using kerogen pyrolysis gas dynamics and isotope dynamics.The simulation result shows that the natural gas in this field is not derived from Cretaceous oil cracking,but from kerogen decomposition of Jurassic coal - measure source rock;massive gas generation started from about 12Ma or 10Ma,natural gas accumulated during about 6Ma.The result of this study is of guiding significance to gas exploration in the south of Junggar Basin.
