Kinetics of the Oil and Gas Generation from Kerogen and Its Application to the Turpan-Hami Basin

摘要: 本文利用热解气相色谱仪(Py-GC),对我国吐哈盆地烃源岩样品进行了热解模拟实验,采用等温一级反应动力学模型,求得了烃源岩热解生成油和气的动力学参数,结合地温梯度等地质参数,计算出了吐哈盆地具有代表性的井位,在不同地质时期的油、气生成率和生成强度。该方法基于化学反应动力学理论,与以往使用的资源评价方法相比,将更为科学,更符合实际情况。Abstract: In this paper, the thermal simulation experiments on the koregen degradation of sauce rocks werecarried out by using pyrolysis gas chromatography. The isothermal experimental data were used to de-velop a kinetic model of oil and gas generation. A new method based on the kinetic reaction theory wasproposed which offers a quantitative approach to the evaluation of natural gas and petroleum. As an ex-ample, the fraction and intensity of the natural gas and petroleum generation were calculated for the dif-ferent burial units of the typical wells in the Turpan-Hamibasin.
